Lincoln Attends Laying of Cornerstone for the Washington Monument

  By

Washington MonumentThe fourth of July, our annual anniversary of the signing of the Declaration of Independence, has always a day of commemoration. Throughout his life, Abraham Lincoln attended many of these celebrations. But July 4, 1848, was even more special than usual. On that date, Lincoln watched the cornerstone of the new Washington Monument being laid.

Lincoln was serving his single term as a U.S. congressman at that time. It would be a busy 1848 year for him. He had given his “spot resolution” speech on the floor of the House of Representatives a few months earlier and would give another speech on internal improvements in another month or so. By September, he would be stumping across Massachusetts in support of Zachary Taylor’s Whig candidacy for president. But Lincoln was not about miss the groundbreaking for a monument for the father of our country.

That monument was a long time coming. George Washington had completed his second term as president in 1897, after which he moved back to Virginia to live out life on his Mount Vernon estate. He died in December 1899. While plans to erect some sort of monument had started even before his death, but disagreement about its form and cost kept the idea in stasis until it began again in earnest in the 1830s. Funding and design disagreements continued until the idea of a simple, but giant, obelisk began construction in 1848.

As might be expected, a large ceremony accompanied the symbolic laying of the cornerstone. Executive officials, congressmen (including Lincoln), various fire companies, school children, and fraternal organizations. This latter group included the Freemasons, the “secret” society of which Washington had been a member. Originally seen as part of Pierre Charles L’Enfant’s grand design for the city, the Monument again ran into funding problems. The core of the monument is made of bluestone gneiss for the foundation and granite for the construction. But that’s just the inside. The outer facing consists of three different kinds of white marble.

Why three kinds of marble? That’s because the lack of funding stopped building progress for many years. The bottom third of the Monument has marble from Baltimore County, constructed from 1848 to 1854. The Monument stump then sat unfinished at a height of 152 feet. And that is what Abraham Lincoln could see every day from the White House as he fought to save the nation during the Civil War. Following the war, Congress eventually appropriated more money, but by this time people were second-guessing the simple design and more embellished plans were submitted. By the time this played out (with the original simple design intact, albeit with some modifications to the foundation to withstand the weight of the additional height) it was 1879. Construction then ran from 1879 to its final completion date in 1888. Initially, marble from Sheffield, Berkshire County, Massachusetts was used, but only for a narrow zone just above the original base. The rest of the obelisk was finished using Cockeysville marble coming from the same quarry town as the original.

Lincoln never got to see the Washington Monument completed, but he not only saw the building of the Smithsonian castle, he also spent a lot of time there during the Civil War. The design of the Castle, the first and only building at the time of what is now a vast Smithsonian Institution complex, had been completed prior to Lincoln’s arrival for his single term in Congress. Construction began just as he arrived and was ongoing throughout his term. The East Wing of the Castle was completed about the time Lincoln left Congress, and Joseph Henry, the first Secretary of the Smithsonian, moved in with his family while construction continued. The West Wing was completed later that year (1849). The exterior took a few more years, finally being completed in 1852 while Lincoln toiled away at his legal practice back in Illinois.

Then came the Civil War and Lincoln came back to Washington as the nation’s president. Joseph Henry became an informal science adviser to Lincoln and several events and signal light tests were done in the Castle. Then tragedy struck just as the four years of horrible war came to a close – the Castle was on fire (read my account of the fire here). One tower was destroyed, along with some of Joseph Henry’s belongings and virtually all of James Smithson’s papers, instruments, and mineral collection.

On the Fourth of July a few years ago, I sat on the hillock at the foot of the Washington Monument. I had spent the day at the Smithsonian Folk Life Festival and was now watching the annual fireworks display bursting across the sky between the Washington Monument and the Lincoln Memorial. Both structures had taken some time to complete, but now, with “bombs bursting in air” above them, it was impossible not to be inspired.

Happy 4th of July!

Rocket Man Abraham Lincoln

  By

It is no secret to anyone who has read Lincoln: The Fire of Genius that Abraham Lincoln was a fan of advanced weaponry during the Civil War. He would routinely entertain inventors promoting their new device “that would surely end the war tomorrow.” Some of those devices were rockets, and one of them almost killed Lincoln.

On this date in 1864, Lincoln was joined by Assistant Secretary of the Navy Gustavus Fox and Senator Orville H. Browning on an excursion from the White House to the Washington Navy Yard. Lincoln frequently visited the Washington Navy Yard to discuss weapons and strategy with Commander John Dahlgren, a like-minded acolyte of technology. On this occasion, according to Browning’s diary, the three men witnessed the “throwing of rockets and signal from six- and twelve-pound guns.” The demonstration went off as planned and no unexpected dangers to the president were evident.

The same cannot be said for another rocket test in late 1862, where Lincoln was perhaps more closely involved than anticipated. This time Lincoln had been joined by Secretary of State William Seward and Secretary of the Treasury Salmon P. Chase on the trip to the Navy Yard, where Dahlgren had planned for them to observe the testing of a Hyde rocket. The Hyde was an improvement of the Congreve rockets that had been used for many decades. It was “red glare” of the Congreve rocket and “bombs bursting in air” that had allowed Francis Scott Key to see “proof through the night that our flag was still there” during the British attack on Fort McHenry in 1814. But the Congreve was little more than a bottle rocket on a stick and unsuitable for the current Civil War. Since then, English inventor William Hale had created a much more advanced rocket using side vents allowing the release of propulsion gases, which caused the rocket to rotate in flight, thus improving its stability, distance, and precision. Hale’s rocket had been introduced in the United States by Joshua Burrows Hyde and received limited use during the Mexican American War of the 1840s. It was an improved version of this newly renamed Hyde rocket that Lincoln and companions were at the Navy Yard to observe.

Hyde rocket patent

The initial launching of the Hyde rocket didn’t go as planned. Rather than arcing across the Anacostia River, the rocket exploded in a fury of fire and smoke. Luckily for all present, the rocket had exploded without even leaving the launcher, thus containing most of the shrapnel and no one was injured. Lincoln would return to the White House while the operator, Lt. Commander William Mitchell, investigated the incident. Two days later, Mitchell was ready to try again. This time, Lincoln, Seward, and Chase remained safely ensconced in the White House, which turned out to be a good decision. The Hyde rocket managed to leave the launcher without exploding, but rather than hitting its intended target it flew out of control and landed on the roof of a nearby blacksmith shop, where again luckily it caused no further damage.

At this point the idea was mothballed and Hyde, although patenting it the following year, gave up on the idea. He did, however, contribute to the war effort in other ways, focusing his later efforts on improving smaller guns and cannons with much better success.

Abraham Lincoln would continue to encourage the development of new weapons throughout the war, which I discuss in more depth in Lincoln: The Fire of Genius. As for rockets, they played only a small role in the Civil War and would have to wait for future wars to be further developed into the weapons of mass destruction we use today.

What Does the Juneteenth Flag Mean?

  By

June 19th – Juneteenth – represents the end of slavery. But how did that come to be so? And what does the Juneteenth flag mean?

Juneteenth flag meaning

As the graphic above notes, Juneteenth is based on the date June 19, 1865, which is the date that Major General Gordon Granger arrived in Galveston, Texas. As the Civil War was ending, Granger had been assigned to command the District of Texas. Upon arrival, he realized that word of emancipation had not filtered down to Texans, and white Texans continued to enslave African Americans. Granger issued General Order No. 3, which began:

The people of Texas are informed that in accordance with a Proclamation from the Executive of the United States, all slaves are free. This involves an absolute equality of rights and rights of property between former masters and slaves, and the connection therefore existing between them becomes that between employer and hired laborer.

The Proclamation to which he was referring was the Emancipation Proclamation, which Abraham Lincoln had issued on January 1, 1863. The Proclamation declared that all people held in slavery in states in rebellion were “thenceforward and forever free.” As one of the states of the Confederacy, Texas was included in the Proclamation and thus all enslaved people were free. White slaveholders kept that information to themselves and hoped to continue to enslave other Americans. Granger’s General Order No. 3 ended that practice.

Technically, the Emancipation Proclamation was a wartime measure, and its authority was in question at that point in time. However, the 13th Amendment to the Constitution had already been passed by Congress (and signed by Lincoln to show his support even though there is no requirement for the president to sign amendments). Several states had ratified it, but officially the 13th Amendment permanently ending slavery in the United States was fully ratified and went into force on December 6, 1865. This is the official end of slavery.

But African Americans have for many decades celebrated June 19th – Juneteenth – as Freedom Day, a day representative of achieving freedom from slavery. Some states had made it a state holiday. In 2021, President Joe Biden made Juneteenth a federal holiday.

Each portion of the Juneteenth flag carries a specific meaning. The red, white, and blue colors remind us that African Americans were, and are, Americans (most of those enslaved by the Civil War had been born in the United States, some tracing family lines back several generations). The arc represents a new horizon, the opportunities and promise that lay ahead for Black Americans. Think of Martin Luther King’s “The arc of the moral universe is long, but it bends toward justice.” The white star in the center symbolizes both Texas (the Lone Star State) and the freedom of African Americans in all fifty states. The starburst reflects the new beginning offered by freedom. And, of course, the date of General Order No. 3.

Enjoy your federal holiday, but also remember the deep meaning behind the date.

The Two “Republican” Conventions of 1864

  By

Abraham LincolnThings were not looking good for Abraham Lincoln and the Republican Party in 1864. The populace was fatigued from over three years of bloody war with no end in sight. Lincoln had finally found a general “who fights” in Ulysses S. Grant, but even Grant was bogged down with a series of inconclusive – and horribly bloody – battles in the Wilderness, Petersburg, the Crater, Cold Harbor. And where the heck was William Tecumseh Sherman, who had gone radio-silent in his march across the South.

Then there was the Republican in-fighting. Treasury Secretary Salmon P. Chase was intriguing behind the scenes to undermine Lincoln’s nomination for reelection. And the Radical Republicans thought Lincoln was too moderate on slavery and racial equality and may not win a second term. Even Lincoln was having doubts. The uncertainty led to a splitting of the party, at least temporarily, and two conventions that were each Republican but called something else.

While Chase backed down, the Radicals in the party sought an alternative candidate. Coming together in Cleveland in May 1864, the Radical Republicans rebranded as the Radical Democracy Party. They nominated the Republican Party’s 1856 presidential nominee, John C. Fremont for president and War Democrat John Cochrane for vice president. Their platform called for a continuation of the war without compromise, a constitutional amendment banning slavery and authorizing equal rights, confiscation of rebel property, congressional control of reconstruction, and a one-term limit on the presidency.

A week later, the rest of the Republican Party, especially those who supported Lincoln for a second term, met on June 7-8, 1864, in Baltimore. Feeling pressured by the split in their own party (with memories of how the Democrats had split in 1860 into Northern and Southern factions, thus ensuring their loss), the Lincoln Republicans sought to broaden their appeal and reflect the national character of the war while providing a place for War Democrats. Like the other Republican faction, this one rebranded itself into the National Union Party. They nominated Abraham Lincoln for president and Democrat Andrew Johnson as vice president. The party platform made many of the same points as the Radical Republicans had, including winning the war, destruction of the Confederacy, and a constitutional amendment ending slavery (although not equal rights or a one-term limit). All parts of the Republican Party agreed on the basic principles, if not some of the more contentious details.

The change in vice presidents was driven by the perceived need to present a more inclusive party. Baltimore convention delegates felt that Hannibal Hamlin, Lincoln’s first vice president, was superfluous. Vice presidents had little to do anyway, but by 1864 the state of Maine was firmly for the union, meaning Hamlin would not bring any substantive new voting cohort to the ticket. Hamlin had leaned more radical, yet had been, and no doubt would have continued to be, loyal to the Lincoln administration. But the delegates felt outreach to the Democrats necessary to assure reelection. Andrew Johnson, at least on paper, seemed a perfect fit. A senator from Tennessee when the war started, he was the only southern senator to remain loyal to the United States when his state seceded. Lincoln would make him the territorial governor of Tennessee during the war, at least that part that had been recaptured by Union forces. Johnson also talked a good game when it came to being hard on the Southern elite he despised (mostly because he had been a poor tailor, and they were rich landowners). He seemed a textbook companion candidate, especially since he likely would not have much of a role for the next four years. That choice would come back to haunt the party and the nation.

So now the Republicans/National Union Party had Lincoln in place to run for a second term. That still left John C. Fremont out there as a potential spoiler. Fremont was not all that happy with Lincoln, who had unceremoniously rescinded Fremont’s emancipation order early in the war and removed him from service. But as the summer progressed, the Radical Republicans/Radical Democracy Party failed to get much traction. None of the Republican newspapers supported Fremont and most Republicans continued to back Lincoln for reelection. Then on September 2, 1864, General Sherman resurfaced to announce he had captured Atlanta on his “march to the sea.” Realizing their lack of support, and that being a spoiler would be disastrous, Fremont and Cochrane withdrew from the race on September 21, 1864. Fremont remained critical of Lincoln, and, behind the scenes, his withdrawal may have been part of a deal with Lincoln in which Radical Republicans forced the removal of Postmaster General Montgomery Blair from the cabinet.

Meanwhile, the Democratic Party, now driven entirely by Southern slave interests, managed to shoot itself in the foot (so to speak). They fervently backed a party platform calling for an end of the war at all costs, most likely by a negotiated peace with no end to slavery and recognition of the Confederacy as a separate country. They then nominated Lincoln’s former General-in-Chief, George B. McClellan for president. McClellan immediately disavowed his own party’s platform to avoid looking like the Democrats were ready to dismiss the sacrifices all who gave their lives in the war (some 750,000 combined). McClellan’s renunciation was effectively negated by the Democrats’ choice of George H. Pendleton as the vice-presidential nominee. Pendleton was a protégé of Clement Vallandigham, leader of the Copperhead faction of the Democratic Party, a faction seen by many as traitorous to the Union.

By early fall, Lincoln’s chances started to seem much better.

Still, the election is never over until the votes are cast. The people still had to vote, and many of them were out in the trenches fighting a war.

[NOTE: On October 15th, join the Lincoln Group of DC as David J. Kent and Ed Epstein lead a discussion of the critical election of 1864. As discussed above, just getting the candidates straight was a complicated chore, but there is much more to the election story. You won’t want to miss it!]

Join Me for the White House Historical Association History Happy Hour, June 6, 2024

  By

History Happy Hour logo

Join me on Thursday, June 6, 2024, for the White House Historical Association’s History Happy Hour. The program is free and begins at 6 pm ET. Register Here to receive the Zoom link.

The White House Historical Association (WHHA) is “a private, nonprofit, educational organization with a mission to enhance the understanding and appreciation of the Executive Mansion.” One of their many initiatives is History Happy Hour, which enables experts to present topics related to the White House and the presidency. True to its name, the Happy Hour begins with a cocktail created by Fernando Sousa on behalf of the program’s sponsor, Diageo North America, from their headquarters in New York City.

My program riffs off my most recent book, Lincoln: The Fire of Genius. I will talk about how Abraham Lincoln helped institutionalize science and modernized America. Lincoln had a lifelong fascination with science and technology and was the only president with a patent. He advocated for technological advancement as a legislator in Illinois and Washington D.C. and became the “go-to” Western lawyer on technology and patent cases during his legal career. For this presentation, I’ll focus on how, during the Civil War, Lincoln drew upon his commitment to science and personally encouraged inventors while taking dramatic steps to institutionalize science via the Smithsonian Institution, the National Academy of Sciences, and the Department of Agriculture.

My guest moderator for the program is John O’Brien, who, like me, is a past president of the Lincoln Group of DC. John will introduce me and then feed me questions from the audience after my presentation. The entire program will take only about 50 minutes, during which we are sure to have a little fun (especially if the audience pours themselves a little “happy hour” refreshment along with Fernando Sousa).

The program is presented virtually via Zoom so pre-registration is required to receive the Zoom link. There is no charge for the program. Register Here.

I hope you will join me. Normally there are around 400 participants in these programs, so I am asking for all Lincoln and science aficionados to sign up!

Register Here!

Out with the Old, In with the New

  By ,

David J Kent Lincoln Memorial centennial

On Tuesday evening, May 21, 2024, I officially became “the old.” At that time, I relinquished the role of Lincoln Group of DC president, handing the gavel (figuratively, since we do not have an actual gavel) to “the new,” President Ed Epstein. In keeping with our long history, we had a peaceful transition.

I get to stay around as the Immediate Past President of LGDC. Lincoln, as you may recall, had the misfortune of being unceremoniously assassinated less than six weeks into his second term. He never got to see the organization carry on after his tenure was completed. Luckily, I will.

I walk away from the presidency after serving three years in that role. Previously, I had served two non-consecutive terms as VP of Education and Outreach sandwiched around one term as VP of Programs. I was fortunate that during my tenure the Lincoln Forum recognized with their Wendy Allen Award the Lincoln Group of DC’s eight+ decades of contributions to Lincoln scholarship. LGDC also organized, and I had the privilege to emcee, the 2022 Lincoln Memorial Centennial celebration on the National Mall. There have been tours, picnics, special programs, and many dozens of superb presentations – both at dinners and via Zoom. I have also had the opportunity to contribute articles to the Lincolnian newsletter in addition to my regular book review column for the last ten years. I have written many posts for the current website news blog and moderated or presented dozens of LGDC programs. And then there was the privilege of sharing one Saturday morning a month for the last ten years with the members of LGDC’s Study Forum as we dug deep into twenty different Lincoln books (and counting).

In short, it has been a wonderful experience.

You can read more about the Lincoln Group and the new board in an article I wrote for Lincolnian.org, from which this piece is derived.

So, what’s next for me?

To begin with, I’ll still be around the Lincoln Group as Immediate Past President. One task going forward is taking on the role of Historian. I’ll also continue to write for the website and newsletter, as well as other Lincoln organizations’ newsletters and journals. I’ll dig into the Lincoln Group’s files and write a full history. Lincoln is still my main focus for the time being.

But I’ll also be exploring the other aspects of my life that need greater attention. As I wrote in my end of year 2023 Travel Post, I will continue to travel the world. Next up is southern Africa. Next year will likely be South America. The following year, Antarctica. I’m also looking at some domestic trips. One area that I’ve been overlooking is the idea of short “excursions,” day trips to local sites or overnighter trips for slightly less local sites. Knowing me, I’m sure there will be more road trips (like the one to Maine coming up).

Then there is the writing. I mentioned in my 2023 end of year Writing Post that I was working on a book proposal, and that work in progress continues. I’ll also be putting out expanded and updated second editions of my earlier e-books as softcover print books – complete with a ton of new material. With more time, I’ll focus on getting the other partial books completed and out the door. And I already have new ideas for the next books, plus some articles for both Lincoln academic journals and popular media.

With so much more to do, I don’t expect to get bored anytime soon.

Abraham Lincoln: The Only President with a Patent

  By

Lincoln Patent ModelAbraham Lincoln is the only U.S. president to own a patent. His idea for “an improved method of lifting vessels over shoals” was given Patent No. 6369 on May 22, 1849. The development of the patent stemmed from his personal experience getting his flatboat hung up on the New Salem mill dam and his observation of a steamship run aground in the shallows of the Detroit River passing Fighting Island. He watched as the captain of the steamship Canada ordered his crew to collect “all the loose planks, empty barrels, boxes, and the like which could be had” and force them under her hull to buoy the ship higher in the water. Ever the inquisitive one, Lincoln was enthralled with the ongoing operation. The incident got him thinking seriously about how to solve this particular kind of problem.

Combining his own experiences and some self-study, Lincoln settled on the physics concept of displacement. He probably picked up the basic idea of displacement in his early studies of geometry when preparing to be a surveyor. Displacement in geometric terms is simply the straight-line distance from one position to another. When applied to ships, this translates into the distance a vessel sinks into the water before its weight equalizes with the pressure of the water pushing up. A ship is said to have a certain degree of buoyancy, defined simply as the ability of something to float in a liquid, usually water.

To raise a ship that has run aground, another concept of physics is employed—the Archimedes principle. Archimedes was an ancient Greek mathematician and physicist who lived in the third century BCE. Among his many discoveries, besides deriving an accurate approximation of π (pi), was the principle of buoyancy that bears his name. In his treatise On Floating Bodies, Archimedes states: “Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object.” He supposedly discovered this principle after noticing that the level of water in his tub rose as he got in to take a bath, realizing this effect could be used to determine the volume of any irregularly shaped object. In practice, displacement is the occupation of a submerged body (like the hull of a ship) that would otherwise be occupied by a liquid, or the weight of fluid that would fill the volume displaced by a floating ship. This is measured in tons, which is why a ship’s size is usually referred to in tonnage.

According to Herndon, Lincoln had watched intently how the Canada’s captain used the power of displacement to buoy up the stranded vessel. Empty casks contain air, much lighter than the displacement of water. As additional lighter-than-water materials were placed under the hull, the ship gradually lifted until it was clear of the sandbar. Lincoln recognized intuitively the application of the Archimedes principle, that the objective of underwater vehicle flotation systems was to counteract the weight of the vessel pushing down with some additional buoyancy pushing up. The wooden planks, boxes, barrels, and casks would provide that buoyancy. As Lincoln continued on his way, he undoubtedly pondered deeply the problem of getting stranded vessels afloat. There had to be a better way. Obsessed with the idea, Lincoln decided to invent that better way.

For his design to lift stranded vessels, Lincoln decided on “expansible buoyant chambers placed at the sides of a vessel . . . in such a manner that . . . the buoyant chambers will be forced downwards into the water and at the same time expanded and filled with air for buoying up the vessel by the displacement of water.” Fleshing out his idea to get the design in line with the physics, Lincoln worked with a Springfield mechanic named Walter Davis to build a working model of the device. How much of the model Lincoln himself manufactured is uncertain, but at the very least he fashioned the central pillars. When it was finished, Lincoln showed off the model in “the big water trough at the corner opposite” his office in downtown Springfield. One witness noted that the four-foot model was set afloat in the trough, then forced downward with bricks to simulate a grounding. Lincoln “then applied the air pumps modeled like the old fire bellows, four in number, two on each side that were beneath the lower or first deck and in a few moments, it slowly rose above the water about six inches.” The gathered crowd, although much impressed, was not entirely convinced the device would help open up the Sangamon River for navigation, but they gave him three cheers for the entertainment value.

When Lincoln returned to Washington for another session of Congress, he sought out Zenas C. Robbins, an experienced patent agent, to help navigate the cumbersome patent process. “He walked into my office one morning with a model of a western steamboat under his arm,” reported Robbins. “After a friendly greeting he placed his model on my office-table and proceeded to explain the principles embodied therein and what he believed was his own invention, and which, if new, he desired to secure by letters patent.” Robbins helped Lincoln create the necessary drawings and paperwork, and the patent application was submitted on March 10, 1849.

While the theoretical concept of the invention was simple, the actual mechanism to achieve buoyancy was somewhat unwieldy, as was the ninety-six-word opening sentence of his application:

Be it known that I, Abraham Lincoln, of Springfield, in the county of Sangamon, in the state of Illinois, have invented a new and improved manner of combining adjustable buoyant air chambers with a steam boat or other vessel for the purpose of enabling their draught of water to be readily lessened to enable them to pass over bars, or through shallow water, without discharging their cargoes; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being made to the accompanying drawings making a part of this specification.

His astounding grasp of both the necessary physics and the intricacy of the design is demonstrated in three accompanying figures—a side elevation, a transverse section, and a longitudinal vertical section—that show the placement of the buoyant chambers on the sides of the vessel.

“Each buoyant chamber,” he explains, “is composed of plank or metal, of suitable strength and stiffness, and the flexible sides and ends of the chambers, are composed of India-rubber cloth, or other suitable waterproof fabric, securely united to the edges and ends of the top and bottom of the chambers.” These are in effect inflatable rubber bellows held in place within a strong collapsible frame that can be raised or lowered as needed. “A suitable number of vertical shafts or spars” would be secured to the bottom part of the bellows and to a main shaft passing horizontally through the center of the vessel. Ropes wound around the main shaft would, upon turning, raise or lower the vertical spars, thus inflating or deflating the chambers.

And on he went, describing in great detail every aspect of the system: how the bellows were to be operated, how the devices were attached to the vessel, how the system of ropes and pulleys was used to manipulate the positioning of the spars. Lincoln even considered the scalability of the design such that it could be operated by manpower on smaller vessels or by steam power on larger steamships. He incorporated enough flexibility in the design to cover a range of mechanical arrangements, thus providing broader protection for his patent. What he claimed as his patent was not to be limited by the specific design shown in the drawings, but the “combination of expansible buoyant chambers placed at the sides of the vessel” and a system to deploy them as needed. When finished, “the buoyant chambers will be contracted into a small space and secured against injury.”

Lincoln had used his still growing knowledge of hydraulics, hydrology, mechanics, and construction to successfully develop an application for “an improved method of lifting vessels over shoals.” After submitting the application, Lincoln put his focus back on his responsibilities as U.S. congressman, which included drafting a bill that would have emancipated enslaved people in the District of Columbia if it had passed. A year earlier Congress had passed a new patent law that gave sole power of issuing patents to the commissioner of patents and increased the salaries of examiners to $2,500 per year, thus increasing the professionalism of the office. A law passed the following year moved the patent office from the State Department to the newly created Department of Interior (originally called the Home Department).

On April 13, Robbins wrote excitedly to Lincoln: “It affords me great pleasure to inform you that I have obtained a favorable decision on your application. . . . The patent will be issued in about a month.” On May 22, Abraham Lincoln received Patent Number 6469 from the U.S. Patent Office, the only president ever to receive a patent. A few weeks later, Lincoln recommended his model creator, Walter Davis, be appointed receiver of the Land Office in Springfield. While he had regaled Herndon with his belief of “the revolution it was destined to work in steamboat navigation,” Lincoln made no attempt to commercialize the invention. In truth, the apparatus was probably heavy enough in itself to weigh down the vessel, plus presented a potentially insurmountable array of ropes and pulleys on the deck that might limit room for cargo or crew movement. Still, the overall concept of inflatable chambers or pontoons has been employed in more recent times to raise sunken ships, so there is some merit to Lincoln’s design even if he never promoted it.

The original patent drawings, lost at some point, were rediscovered in 1997 in the patent office director’s office. The original model is stored in the Smithsonian Institution’s vault. A second model, and possibly a third, may also exist. Clark Moulton Smith, who was married to Mary Lincoln’s sister Ann, found the second model in the attic of Lincoln’s Springfield home shortly after his assassination. The model was given to Shurtleff College in Alton but disappeared after the college closed in 1957. In 1864, Adam S. Cameron requested Lincoln’s consent to reproduce the model for the benefit of the Sanitary Commission. Given Lincoln’s prominence, the model was sure to fetch considerably donations that the commission would use to support sick and wounded Union soldiers, according to Cameron. There is no evidence this third model was ever created.

Lincoln and the Permanent Commission of the Navy

  By

Lincoln testing a SpencerLincoln’s enthusiasm for mathematics, science, and technology made him a national sounding board for innovations, but he simply could not handle all the inventors pouring letters into his mailbox or showing up at the White House expecting a stamp of approval for their miraculous “war-ending invention.” Unlike today, there was no military-industrial complex developing new weapons during the Civil War. When it came to innovation, the government relied on “the chance, unreliable labors of inventors and amateurs of science” who “literally besieged official Washington after the outbreak of the war.”

Probably with Lincoln’s knowledge, Joseph Henry proposed to Secretary Welles an advisory board to serve as a more efficient mechanism for evaluating new ideas to aid the war effort. The navy had earlier tried a similar idea with its Naval Examining Board, but it failed in six months due to insufficient funding. By early 1863 Welles was willing to implement Henry’s idea, in part because any experimental research would be conducted by the originator, not the navy. With Lincoln’s approval, Welles created the Permanent Commission of the Navy Department “to which all subjects of a scientific character on which the Government may require information may be referred.” The three-member commission—Henry was joined by equally ubiquitous Alexander Dallas Bache (superintendent of the Coast Survey) and Charles Henry Davis (chief of the Bureau of Navigation)—met several times a week to evaluate the stream of proposals. After more than three dozen meetings in the first few months, Henry grumbled to Harvard botanist Asa Gray that his duties on the commission were overwhelming; the commission “occupied nearly all my time” other than that devoted to Smithsonian business.

From its creation in early 1863, the commission evaluated over three hundred proposals ranging from warship designs to underwater guns to torpedoes, all of which their originators claimed would immediately end the war in the Union’s favor. Despite the optimism of the inventors, mostly these ideas were oversold and underperforming. After the war, Henry bragged that the Permanent Commission kept the government “from rushing into many schemes which, under guise of patriotism, were intended to advance individual interest.”

The commission relieved Lincoln of the steady stream of inventors that had besieged him since the beginning of the war, but it did not stop all of them. Lincoln continued to receive letters and visits for the remainder of the war, and the always curious commander-in-chief continued to personally test some of the weapons that came his way. As the burdens of war became overwhelming, more and more often Lincoln would refer inventors to the Permanent Commission or directly to the military personnel most likely capable of evaluating the proposal.

And yet inventors still badgered Lincoln even after their proposal had been evaluated by the commission, either because the commission had refused their self-professed miraculous discovery or because a decision was bogged down in endless bureaucratic delay. John H. Schenk angrily wrote to Lincoln in early 1864 complaining he had been waiting a year to get approvals, yet the evaluation “is still throttled nearly to death with Red tape.” A few months later, John D. Hall wrote to Lincoln about his idea to lay cable across waterways to cut enemy obstructions lower than the keel of Union ironclads. He had originally written to Gideon Welles, who forwarded it to the Permanent Commission, and now impatiently was writing Lincoln. He complained that “notwithstanding these devices are so simple that any mechanical mind may easily comprehend them in the space of ten minutes of time,” he had yet to receive any report after thirty days. He asked Lincoln to speed up the acceptance. He received a reply that his invention was under consideration. Sometimes even Lincoln’s positive intervention had no effect. Inventor Peter Yates had proposed an “Improvement on Steam Engines” that was the subject of several letters between Yates, Lincoln, Welles, and the members of the commission. In the end, Charles Henry Davis grumbled to Welles that the “invention has not been described with sufficient clearness to be perfectly understood,” but based on what he could infer, “the loss of power which this invention is intended to prevent does not exist.”

On the other hand, Thomas Schuebly wrote Lincoln in late 1863 enthusiastically thanking him for supporting development of his new “impregnable” ironclad steamer, which the Permanent Commission told him to build at his own expense. Testing of this new ironclad, Schuebly cautioned in his letter, would be delayed slightly. It apparently was never built.

Despite its name, the Permanent Commission petered into nonexistence midway into 1865 as new weaponry became less important than mass manufacture of conventional rifles for the postwar occupation. The idea has been resurrected over the years as new wars required evaluation of new technology. One such board, the Naval Consulting Board, was chaired by Thomas Edison during World War I and led to the creation of the internally integrated Naval Research Laboratory, which still exists in Washington, DC.

More information below per the York CWRT website:

David J. Kent will speak on the topic of “Lincoln’s Influence on Science and Technology in the Civil War.” Abraham Lincoln had a lifelong fascination with science and technology, a fascination that would help institutionalize science, win the Civil War, and propel the nation into the modern age. Kent will discuss how science and technology gradually infiltrated Lincoln’s remarkable life and influenced his growing desire to improve the condition of all men. The presentation will show where Lincoln gained his scientific knowledge, and how that background led him to encourage its further development and use during the war.

David J. Kent is an Abraham Lincoln historian, a former scientist, and the current President of the Lincoln Group of the District of Columbia. He is also on the Executive Committee and Board of Directors of the Abraham Lincoln Institute and the Board of Advisors of the Lincoln Forum. He is a frequent speaker on Abraham Lincoln topics and served as Master of Ceremonies for the Lincoln Memorial Centennial program in 2022. David has won numerous awards both for his scientific work and as an Abraham Lincoln historian. He has written several books, including his most recent, Lincoln: The Fire of Genius: How Abraham Lincoln’s Commitment to Science and Technology Helped Modernize America and his previous Lincoln book for young people, Lincoln: The Man Who Saved America. He has also written books on Nikola Tesla and Thomas Edison. He is currently working on a book about Lincoln’s two visits to New England.

The York Civil War Round Table is a non-profit organization that seeks to promote, interpret, preserve, and protect the Civil War heritage of York County, Pennsylvania, through the education and exchange of information with its members and the general public. Membership is free and open to anyone interested in learning more about the American Civil War.

Founded as the White Rose Civil War Round Table, the York CWRT holds monthly meetings the third Wednesday of every month except December at 7:00 p.m. in the Meeting Hall of the York County History Center’s Historical Society Museum at 250 East Market Street in York, Pennsylvania. Each meeting features a guest speaker talking about a Civil War topic of local or national interest. Meetings are FREE and open to the public.  For upcoming programs, please visit the Cannonball webpage http://www.yorkblog.com/cannonball/york-cwrt/.

Unexpected Lincoln – The Other Booth Brother in Manchester-by-the-Sea

  By

Junius_Brutus_Booth_Jr_-_Brady-HandyWe all know John Wilkes Booth, the assassin of President Abraham Lincoln. And then there was Edwin Booth, the great Shakespearean actor known for his performances of Hamlet. But there was another Booth brother in the acting business, and you won’t believe where he showed up in this edition of Unexpected Lincoln.

Junius Brutus Booth, Jr. was the eldest son and namesake of the great British/American actor (not surprisingly named Junius Brutus Booth, Sr.). The Senior Junius Booth was considered one of the greatest actors of his time, that is, when he wasn’t having mental health and drinking issues. After abandoning his wife and son in England, Junius Senior absconded to the United States with Mary Ann Holmes, a flower girl he has just met. They had twelve children together, most notably the three actor brothers and their sister Asia. Junius Junior was the least known of the three, an okay actor that never reached the fame (and infamy) of his two younger siblings. Only once did the three brothers perform together on stage, in Julius Caesar (ironically, or perhaps presciently, Caesar and Brutus entered into John Wilkes’s thought processes when contemplating the assassination of Lincoln).

Booth, Jr., like all of the Booth actors, had an erratic life, including three marriages. The first was brief, the second died giving birth to their only child (who somehow lived a long life, dying at age 78 in 1937). Booth, Jr. was out in California for much of the Civil War, returning east in 1867 to become manager of the Boston Theatre, and married an Australian-born widow, Marion Agnes (Rookes) Perry, who was also an actress and dancer thereafter known as Agnes Booth.

Here’s where the unexpected comes in.

While managing the Boston Theatre (in, obviously, Boston, Massachusetts), Booth Jr. started a hotel and summer theater operation in Manchester-by-the-Sea, a Massachusetts seacoast town on Cape Ann north of Boston. [BTW, there was a critically acclaimed film of the same name starring Casey Affleck in 2016 that is definitely worth seeing]. I’m quite familiar with Manchester-by-the-Sea as it’s close to my hometown and my grandmother lived there for 102 years. I was completely unaware, however, that the aforementioned Junius Brutus Booth, Jr. had a hotel and summer stock theater there and, in fact, is buried in the cemetery I had passed hundreds of times.

Booth House_Masconomo House_Manchester MA

Having recently discovered this fact, I made a beeline for Manchester on my recent road trip to New England. And there it was. First, the hotel. On the narrow road just before the famous Singing Beach was an old house (above) that I had barely noticed on my many walking trips down that road. The main house is where Junius and Agnes lived while they let out rooms in the hotel extension next door. Most of the hotel portion burned down early in the 20th century, but a small part of it remains as the residence of the current owners, who now make the main house (the original that survived the fire) available for rental at a hefty price per night. It’s a short walk to the beach. This is the house that Booth built.

After finding the house (which, to be honest, could use some landscaping work), I drove up the road to the Rosedale Cemetery. I had seen a photo of the gravestones on Find-a-Grave (an incredibly useful website for finding dead people) but it didn’t give a location in the cemetery. This was the third cemetery I visited on this particular road trip; the first two conveniently told me the exact location. This one didn’t but the photo seemed to show the graves near a granite wall, so I circled the cemetery perimeter looking for a granite edge. Almost giving up (the cemetery is mostly ringed by a wrought iron fence), I suddenly noticed the unique shape of Junius, Jr.’s tombstone. Quickly pulling over into a miraculously available parking spot, I confirmed that this was the correct spot. In this section, the wrought iron fence sat atop a short granite wall base.

Junius Booth’s gravestone is literally an open book, which is how I was able to locate it so quickly. The book appears open to its middle pages and sits on a short pedestal such that the top is maybe three feet off the ground. The inscription is worn with age but still legible if you look closely. Oddly, it says he died in September 1884 while all the other information says he died in 1883 at age 61. Next to him is the scroll-like gravestone of his last wife, Marion Agnes Schoeffel. Yes, that’s Agnes Booth. Even though she remarried to a man named John B. Schoeffel, Agnes chose to be buried next to her more famous second husband and three of their children. The next Junius in line, their son Junius Brutus Booth III, died by suicide in 1912 and is buried in Brightlingsea, Essex, England.

Like his brother Edwin, Junius Jr. had been hauled into Old Capitol Prison in Washington, DC after their more infamous brother John Wilkes had assassinated Abraham Lincoln. Both Edwin and Junius Jr. were interrogated and released, and both went on to continuing careers in the theater after short hiatuses. By the way, Edwin had an encounter with another Lincoln, having famously saved the life of Robert Lincoln at a train station in late 1864 or early 1865. See more about that incident here. Junius ended up in New England, and the rest, as they say, is history.

Unexpected Lincoln is on the trail of other little-known connections to Lincoln, including more from my New England road trip that I’ll relate soon.
