Thomas Edison Invents the Movies

  By

Edison KinetoscopeOn August 31, 1897, Thomas Edison invented the movies. Or at least that was the day he patented the kinetoscope, an early motion picture projector. But as with all inventions, the story is much more complicated than just one man.

In fact, others had already started the process that Edison’s team would move forward. In June 1889, William Friese-Greene had patented a motion picture camera in England. Two months later, Englishman Wordsworth Donisthorpe patented his own version of a motion picture camera. Louis Aimé Augustin Le Prince, a Frenchman working in England, developed a multiple-lens camera in 1888. Le Prince also filmed two motion picture sequences using a single-lens camera and paper film; the twelve-frame-per-second Roundhay Garden Scene runs for a grand total of 2.11 seconds. In a bizarre twist reminiscent of future action movies, Le Prince and his luggage mysteriously vanished from a moving train just prior to making a trip to the United States to present his invention.

These early inventors did not have the finances to continue development, but Edison did. The first version out of the Edison laboratory was “rather too ambitious,” as it attempted to synchronize the sound of the phonograph with the movement of images. “Thousands of tiny images” were taken with a conventional camera, and one by one they were mounted on a modified phonograph cylinder. A second cylinder played back the sound, ideally in sync with the images. But the machine did not work. The curvature of the cylinder distorted the small images, so it was nearly impossible to view them with any resolution. Increasing the size of the images to 1/4 inch and applying a photographic emulsion to the cylinder failed to resolve the problem, although Edison did produce a series of short films (of a few seconds each) collectively called Monkeyshines. Overall, however, the idea of using cylinders was abandoned.

Another Englishman, Eadweard Muybridge, came to the rescue. Muybridge was a photographer who as far back as the 1870s was producing images in series, which he used mainly to study the motion of animals. In one sequence, Muybridge had taken twelve rapid photos of a horse in full gallop in order to determine if all four legs were off the ground at the same time (they were). He accomplished this by using multiple cameras to record images in rapid succession.

Muybridge had also invented a zoopraxiscope, a rotating glass wheel and a slotted disk that projected a series of pictures in sequence, each slightly ahead of the other. Turning the wheel made the pictures appear to be in motion. With these devices in hand, the now-famous Muybridge paid a visit to Edison during a tour of the United States in February 1888. As with his earlier visit with Wallace, Edison gained considerable insights into his next steps after this meeting. Edison barely acknowledged the visit for months, but in October suddenly submitted his caveat to the patent office for “a system of motion pictures: a device to record the images, a device for viewing them, and an instrument that merged viewing pictures and listening to sound in the same experience.”

Étienne-Jules Marey was another influence on Edison’s thinking about motion pictures. After growing up in the Côte-d’Or region of France, Marey studied medicine and became interested in the science of laboratory photography; he is widely credited with being the Father of Chronophotography, or photographing motion. In 1882 he invented the chronophotographic gun, a menacing-looking instrument capable of capturing images at a rate of twelve frames per second. All twelve sequential still images were recorded on the same strip of film, a disk that rotated as the rapid-fire photos were taken. Marey also designed a camera that captured “sixty images a second on a long continuous strip of film, which was pulled by a cam in a deliberately jerky fashion to stop the film momentarily, so that the light could saturate the film and capture motion.” Edison sought out Marey when he attended the 1889 World’s Fair in Paris.

The World’s Fair’s biggest attraction was the huge iron-latticed tower named after its designer, Alexandre Gustave Eiffel, on whose edifice Edison wined and dined with the rich and famous during the exposition. But what really caught Edison’s interest was Marey’s photographic gun. Marey was more focused on the technical developments of his invention and less about the market value, and he gladly showed Edison the mechanics and examples of his work. He also gave Edison a copy of his book providing all the technical details. Armed with new ideas, but still lacking in substantive time to develop them, Edison passed the information to Dickson and left him to make something of it.

The Kinetoscope Emerges

Edison’s patent caveat was filed with Dickson working anonymously in the background. The device they had in mind would not only show pictures in motion, it would do so “in such a form as to be both Cheap[,] practical and convenient. This apparatus I call a Kinetoscope ‘Moving View.’”(The name is derived from the Greek kinesis, meaning motion.) They described it as a silver emulsion-coated phonograph cylinder with 42,000 “pin-point” photographic images each 1/32 inch wide mounted spirally upon it, to be viewed through a binocular eyepiece salvaged from a microscope; the visual cylinder spun to the simultaneous accompaniment of a contiguous phonograph sharing the same shaft and playing the “sound track.” The idea of synchronized cylinders was completely unworkable, but it epitomizes how Edison worked—he built on something he already did, and he hesitated to move away from it.

But move away he did. Dickson searched for a way to take and display the thousands of pictures that would need to be strung together for any length of viewing time. The usual way of making photographs was to produce them on glass negatives, which clearly was not an option for moving pictures. One option that seemed viable was celluloid, a plastic material made out of cellulose nitrate that English photographer John Carbutt successfully used. Another promising option was rolls of paper that George Eastman had managed to coat with photographic film and fused into a cheap Kodak camera.

Dickson experimented with celluloid and paper, and after Edison’s visit with Marey filed a new patent caveat, this one describing a “sensitive film” that would “pass from one reel to another.” Then, like the phonograph before it, the kinetoscope project was dropped—this time for only a year—while Edison kept Dickson busy with his ore milling business. When Dickson was finally allowed to return to the kinetoscope, Edison assigned William Heise to give him a hand.

Heise had expertise stemming from his prior work with printing telegraphs, which he now used to design the mechanical movement of film through the camera. Dickson focused on the optical components of the camera itself, along with the chemical and physical characteristics of the film. Together they developed the two parts that would make it possible to film, and then display, motion pictures.

By the spring of 1891, the two men had designed a camera, which they called a kinetograph, to film moving pictures. The kinetograph’s horizontal-feed exposed images on strips of perforated film 3/4 inch wide. A “shutter and escapement mechanism” allowed the camera to stop the film “for a fraction of a second,” just long enough to expose the film before advancing to the next exposure. Dickson and Heise advanced the technology with amazing rapidity: “forty-six impressions are taken each second, which is 2,760 a minute and 165,600 an hour.” Several short experimental films were produced, “including a lab worker smoking a pipe and another swinging a set of Indian clubs.”

After developing a suitable camera to create motion pictures, they needed to develop a way to watch them. The answer was a wooden box, much like those housing phonographs, which they called a kinetoscope. The box stood about four feet high and was twenty inches square. Inside the box was “an electric lamp, a battery-powered motor, and a fifty-foot ribbon of positive celluloid film arranged on a series of rollers and pulleys.” The film viewer would bend over the box, stare through an eyepiece, and watch as the film whizzed through view at forty-six frames per second.

And whiz it did. The first films were over in twenty seconds or less; basic scenes such as Dickson tipping his hat or a blacksmith banging his hammer. Still, it was a start, and Dickson continued to work on perfecting both the kinetograph camera and the kinetoscope player. Edison, on the other hand, was not sure there was much of a market: “This invention will not have any particular commercial value. It will be rather of a sentimental worth,” something of a novelty. At the same time he seemed to recognize the future attraction to the new medium, which could reproduce on the walls of their homes actors and scenes they currently had to go out to the theater to experience. Despite his hesitations, Edison arranged for a kinetoscope exhibit at the Chicago World’s Fair. It was a couple of years in the future, so he had plenty of time to perfect the device. Or so he thought. He assigned James Egan, one of his machinists, to build twenty-five kinetoscopes.

Enter the Black Maria. Edison became a movie mogul.

Lincoln Explains to Conkling Why the Emancipation Proclamation Was Necessary

  By

Emancipation ProclamationOn August 26, 1863, Abraham Lincoln wrote a letter to James C. Conkling, his friend and political colleague in Springfield, explaining why the Emancipation Proclamation was necessary. In it he reveals the thought processes he went through to reach his decision. It was a much longer process than most people understood.

In fact, by the early spring of 1862, Lincoln had privately decided to issue an emancipation order. He kept this decision to himself for many months while secretly drafting his arguments. Meanwhile, he publicly voiced apprehension about such a decision, suggesting that turning the rationale of the war from maintaining the Union to freeing the slaves would cause significant loss of northern support, in addition to creating potentially disastrous implications in the border states.

In April 1862, at Lincoln’s urging, Congress emancipated slaves in the District of Columbia and compensated their owners. That June, Lincoln signed a bill prohibiting slavery in all current and future U.S. territories. Most of these steps went largely unnoticed to anyone not directly affected, but they helped move public sentiment toward freedom. Unbeknownst to anyone, Lincoln was preparing a draft of the now-famous document as he shuttled between the Soldier’s Home where he spent his summers and the telegraph office of the War Department. After some surreptitious lobbying of public opinion over the summer, Lincoln finally released his preliminary Emancipation Proclamation on September 22, 1862. Written in dry, legal language, the proclamation stipulates that on:

…the first day of January [1863], all persons held as slaves within any state, or designated part of a state, the people shall then be in rebellion against the United States shall be then, thenceforward, and forever free…

The initial reaction was as Lincoln expected. Many of the more radical Republicans were ecstatic, while Democrats and other “peace at all costs” proponents saw it as an unnecessarily extreme act. Many voters agreed; Republicans lost twenty-eight seats in the House of Representatives that November. As Lincoln feared, many northerners were vehemently opposed to a civil war to free the slaves as opposed to preserve the Union. Despite these losses, Lincoln stood by his decision and signed the final Proclamation on January 1, 1863.

Nearly a year later there was still grumbling in the North about the emancipation order. In August 1863, James Conkling invited Lincoln out to Illinois to explain to supporters why he proclaimed slaves free, some questioning whether it was right to do so. Many were worried that the public would not support the idea of fighting for “negro freedom.”

In his reply letter, Lincoln says his wartime duties precluded travel to Illinois, but explained to Conkling why he believed the Emancipation Proclamation was right. He noted their concerns, but reminded them that many African-Americans, both former slave and freemen, had joined the Union army and navy. He also suggested that Union forces and the public sentiment should continue fight to save the Union irrespective of their views on freeing the enslaved population.

You say you will not fight to free negroes. Some of them seem willing to fight for you; but, no matter. Fight you, then, exclusively to save the Union. I issued the proclamation on purpose to aid you in saving the Union. Whenever you shall have conquered all resistance to the Union, if I shall urge you to continue fighting, it will be an apt time, then, for you to declare you will not fight to free negroes.

Near the end of his letter he again reminded white Northerners that the emancipation of enslaved people and the saving of the Union were intertwined, that one assured the other. He also reminded them that all men, black and white, had made sacrifices to maintain the Union, as well as have a Union worth maintaining. Victory was in sight.

Peace does not appear so distant as it did. I hope it will come soon, and come to stay; and so come as to be worth the keeping in all future time. It will then have been proved that, among free men, there can be no successful appeal from the ballot to the bullet; and that they who take such appeal are sure to lose their case, and pay the cost. And then, there will be some black men who can remember that, with silent tongue, and clenched teeth, and steady eye, and well-poised bayonet, they have helped mankind on to this great consummation; while, I fear, there will be some white ones, unable to forget that, with malignant heart, and deceitful speech, they have strove to hinder it.

As with his earlier letter to Horace Greeley, Lincoln intended and knew that his letter to Conkling would be reprinted in the nation’s newspapers, thus ensure wide distribution of his policy explanation. This was one mechanism by which Lincoln both heeded public sentiment and helped influence it. [He also had John Hay and John Nicolay ghostwriting editorials, but that’s a topic for another post.]

Lincoln wasn’t finished, of course. He understood that the Emancipation Proclamation was a war measure but a more permanent solution was necessary once hostilities ended. Lincoln then set on both winning the war and pushing for what became the 13th Amendment to the Constitution, banning slavery and making all men and women “thenceforward, and forever free.”

Abraham Lincoln’s Introduction to Slavery

  By

Lincoln and slaveryAbraham Lincoln didn’t see much slavery as a small child growing up in northern Kentucky, or through his formative years in Indiana. But he did get an introduction of sorts.

First, the church that his family belonged to in Kentucky began splitting off into northern (anti-slavery) and southern (pro-slavery) factions. Lincoln’s father Thomas followed the anti-slavery group and then moved into the free state of Indiana. When he was nineteen years old Lincoln made his first of two flatboat trips down the Mississippi River to New Orleans, where he encountered his first slave markets and was attacked by escaping slaves. But largely he had little contact with slavery until adulthood.

While still living in New Salem, Lincoln was elected to the first of four terms in the Illinois state legislature. Most of his time was focused on economic issues such as internal improvements but the slavery issue did play one important role. As I wrote in my book, Lincoln: The Man Who Saved America. 

Although the Illinois constitution banned slavery, it did have highly restrictive “black laws” that effectively limited the ability of free blacks to live and work in the state. At the same time, abolitionists who wanted a nationwide ban on slavery were gaining strength and influence. This led pro-slavery forces to push for anti-abolition resolutions. While Lincoln abhorred slavery—he later said, “I am naturally anti-slavery. If slavery is not wrong, nothing is wrong”—he also felt the abolitionists were doing more harm than good. When the Illinois legislature passed an anti-abolitionist resolution, Lincoln was one of only six house members to vote against it. To clarify this seemingly counterintuitive position, he later wrote a protest, co-signed by Dan Stone, one of the Long Nine who was not seeking reelection. In the protest, the two men made clear they believed:

… that the institution of slavery is founded on both injustice and bad policy; but that the promulgation of abolition doctrines tends rather to increase than to abate its evils.

And further, he said they believed:

… that the Congress of the United States has no power, under the constitution, to interfere with the institution of slavery in the different States.

Lincoln wanted everyone to understand he was anti-slavery, but also felt bound by the Constitutional restrictions on taking action against the “peculiar institution.” These were fairly radical thoughts for a young western legislator, and would set the stage for Lincoln to become a national leader on the issue of slavery.

Lincoln knew that slavery was tacitly acknowledged in the Constitution by its “three-fifths rule” and “fugitive slave clause.” He also knew that the framers of the Constitution had believed slavery would eventually go away. They took steps to help that process by passing the Northwest Ordinance (banning slavery in territories that became Ohio, Indiana, Illinois, Michigan, Wisconsin) and, as soon as possible, banning the international slave trade. For most of his early career, Lincoln also believed that slavery would eventually disappear (“founded on injustice and bad policy”). Unfortunately, the invention of the cotton gin and vast expansion of the U.S. territories through the Louisiana Purchase and Mexican War had the opposite effect. Rather than dying away, slavery was threatening to expand into all the western territories and even the free northern states.

Something had to be done. The Kansas-Nebraska Act of 1854, pushed through Congress by Lincoln’s rival Stephen A. Douglas, “aroused him as he never had been before.” It was time for Lincoln to get back into politics.

Nikola Tesla and the Power of the Tides

  By

Tesla: Renewable Energy Ahead of Its Time “Many a deluded inventor has spent years of his life in endeavoring to harness the tides.” – Nikola Tesla

Anyone who has seen the tidal surge in the Bay of Fundy can envision the potential of harnessing the natural power of tides for electricity generation. And today some people are doing just that.

The basic principle is simple. Depending on where you are on the planet, either once or twice each day there is a rise and fall of ocean water we call tides. For any given location this ebb and flow is highly predictable; tide tables can be printed up years in advance. It is possible to build reservoirs to capture the water in rising tides, then during low tide allow that water to flow downward through power plants to generate electricity.

The most common mechanism for harnessing tidal energy is the tidal barrage, which looks like a dam or the locks in canals. Incoming tidal water is allowed to move freely upstream. At peak high tide the barriers are closed and the water shunted through turbines. Another modern option would be to set fixed direct drive turbines underwater in areas with large tidal flows. Other more speculative methods include building what in essence is a “tidal reef,” vertical-axis turbines, and even something called “push plates.” The benefit of tidal power, which Tesla would have appreciated, is that once the system is built the energy would be free, predictable, and naturally renewable. On the down side, which Tesla would also appreciate from experience, the initial development and construction is very expensive.

During Tesla’s time there were some engineers who looked at the potential of tidal-generated power with favor. Tesla was not one of them. In fact, he was rather disdainful in his dismissal of the attempts. “Many a deluded inventor has spent years of his life in endeavoring to harness the tides, and some have even proposed to compress air by tide or wave power for supplying energy,” he snorted. With an estimated “little more than one horsepower” possible over an acre of ground, Tesla felt that a “wave or tide motor would have but small chance of competing commercially” with other natural sources of energy. So here Tesla was in agreement with Lord Kelvin, one of the world’s most respected scientists during the late 19th and early 20th centuries, who had stated that “the tides cannot furnish any power worth speaking of.”

Tesla may have been correct in his assessment. Today, tidal power has been employed only in a small number of locations around the world. The first was located in La Rance, France; the largest is in South Korea. Prospective sites where tidal power would be financially feasible in the United States are few and while countries such as China, France, the UK, Canada and Russia may have greater number of feasible sites, until recently not much has been done to utilize this form of renewable energy.

In the end, Tesla was convinced that only “in exceptional locations can the power of the tides be profitably developed.” He would leave tidal power development for others to pursue. Tesla had other renewable resources on his mind.

Abraham Lincoln and the McCormick Reaper

  By ,

One of Abraham Lincoln’s most famous cases is one in which he never actually tried. On my second Chasing Abraham Lincoln tour I made an unplanned stop at the McCormick Farm, now part of the Shenandoah Valley Agricultural Research and Extension Center.

As populations grew the need for improved crop yields increased, and the mechanical reaper made that possible. Cyrus McCormick had invented a reaper that became the gold standard and stimulated others to “borrow” his ideas. McCormick sued rival John Manny for patent infringement, accusing him of stealing the McCormick reaper design. Manny’s lawyers called in Lincoln because of his jury skills and his local presence in Illinois, but then the case was transferred to the district court in Cincinnati, Ohio. Lincoln spent considerable time preparing for the case and writing a technical brief, but when he arrived in Cincinnati he was shocked to learn that an esteemed Ohio lawyer, Edwin Stanton, had been hired and his own services were no longer needed. Worse, Stanton treated Lincoln poorly, writing him off as a hick western lawyer of little value. While angry at being tossed out of what he thought was his case, Lincoln turned it into an educational experience, watching the trial and learning a great deal about how more classically educated eastern lawyers worked a case.

The era of farm mechanization had begun, and Lincoln the President later relied on his experience to push for and begin the U.S. Department of Agriculture to enhance the use of science in farming. McCormick’s reaper eventually led to the modern combine harvester; his company eventually merged with others to form International Harvester.

The McCormick Farm is a well preserved set of eight original buildings, including a grist mill, blacksmith shop, slave quarters, carriage house, manor house, smoke house, schoolroom, and housekeeper’s quarters. The original ice house was torn down in the 1960s. Outside the grist mill a wooden water wheel creaked eerily as it continued to turn after all these years. Inside, the mostly wood gear mechanisms showed how the grain was ground into meal. There are two sets of mill apparatuses: one solely for corn, the other for wheat and other grains. Grain is fed from a hopper in the upper level and ground at mid level while the main drive shaft and gears take up most of the lower level.

Another main building had the wood shops in the lower section and a museum in the upper section. Here there were many models of different McCormick reapers, a full-size original reaper, and tons of information about the history of the farm and the inventor. On the wall hung an old scythe and cradle, hand tools used to mow and reap crops before invention of the reaper. While onsite I also checked out the small blacksmith shop and water well.

Before leaving I left my name and website address in the guest book. Shortly after my return home I received an email from Amanda Kirby, an assistant at the Research and Extension Center, thanking me for my visit and providing some additional information and resources for the book I’m researching. All along my Chasing Abraham Lincoln road trip routes I’ve met many hugely interesting and helpful people, from local librarians to small museum curators to volunteers at courthouses. The tours have been a great way to study all things Lincoln.

To Kiss or Not to Kiss: Blarney Castle

  By

Blarney Castle, IrelandYou’ve heard the schtick. Visit Blarney! Kiss the Blarney Stone! Gain the gift of eloquence! But should you do it? To kiss, or not to kiss, that is the question. Whether ’tis nobler in the mind to suffer the slings and arrows of outrageous condemnation by friends and family who bagger you with the question: “So, did you kiss the Blarney stone or not?”  Or to take up arms against a sea of tourists who pay big bucks to participate in nothing but a huge tourist hype…and by opposing, end them.*

*With apologies to Shakespeare’s Hamlet for disheveling his famous soliloquy.

The ultimate choice is, of course, up to you. Finding myself wandering around the Blarney Castle one rainy July day, I felt almost obligated to kiss the Blarney stone. Not from some Lonely Planet “must-do tourist check-the-box” list, but from the fear of hearing it from the Irish portion of my family bloodline. Okay, I admit it. This was kind of a bucket list thing for me and I really wanted to do it. So I did, thank you very much.

Blarney Castle, Ireland

Climbing the ever-narrowing tower steps to the top of the castle was at least dry, even if it did rekindle my mild claustrophobia. Half the castle was blocked by a green-mesh coated scaffolding for the most recent (continuing) renovation. Once at the top I joined a line of like-minded tourists (um, explorers) waiting for their chance to be manhandled into a narrow crevice. I must have missed the memo on this part but to kiss the Blarney stone – technically just the inside of the outer wall of the castle – you have to lie on your back, dangle your upper body into a small cutout hole in the roof, and while hoping the grip of the attendant on your body doesn’t slip due to the rain, lean back and kiss the stone upside down and backwards. Seriously, it’s like yoga at 90 feet. To ensure you get the most of the experience, a few widely spread iron bars are the only thing between your sightline and the ground far below. Please don’t lose your grip on me, Mr. Attendant. Jus’ sayin’.

After safely climbing down the stairs in the opposite tower, I walked around the grounds a little. If you get a good day (it rained the entire week I was in Ireland), take the time to walk through the gardens and check out Rock Close, a small natural enclave on the castle property.

Blarney Castle, Ireland

Usually I pass on the obligate “official photo,” but this time I was with family and thought it might be a good keepsake despite the rather unflattering photo. Only later did I hear stories of locals peeing on the stone at night and laughing heartily at the rock-kissing tourists at the local pub. Worse, that the stone and the accompanying hole was once a medieval toilet.

Sorry, I have a sudden urge to gargle a bottle of Listerine. But hey, if you want to kiss the Blarney stone, by all means do it. I did. Now, where did I put that bottle?

Upcoming Abraham Lincoln Talks in Washington, DC

  By

David J Kent 2019This has been a very busy summer in Lincoln world. For me personally I have two upcoming presentations in Washington, D.C., including keynoting a major annual event at Fort Stevens. And both are free (so come on down).

The Lincoln Group of DC, of which I am a Vice President, suspends our monthly dinner meetings and author lectures for June, July, and August. That doesn’t mean we’re not active. In early June we held our annual guided tour, this year at Manassas Battlefield Park. Our monthly Lincoln book study group continues to meet every month except August. And members and officers are busy preparing for future events, publishing the newsletter, reviewing books, and lining up speakers for our fall and spring dinner meetings. [See the Lincoln Group website for the great slate of speakers we have scheduled.]

Lincoln’s Nomination: The next summer event arrives in about ten days from this post. I will join Lincoln Group President John O’Brien and Lincoln Group Recording Secretary Ed Epstein in a special mini-symposium at the New York Avenue Presbyterian Church (“Lincoln’s Church”) in downtown Washington DC. The event takes place Saturday, August 3rd from 10 am to 12 noon. Even better – it’s FREE! The focus will be “Lincoln’s Campaign for the Presidential Nomination” and John, Ed, and I will delve into Lincoln’s renewed political zeal after the passage of the Kansas-Nebraska Act of 1854 and his ensuing path to the surprise Republican nomination. We will also relate it to the eerie parallels to today’s political climate. It’s a program not to be missed. More information on the Lincoln Group website.

Lincoln-Thomas Day Keynote: I’m happy to announce that I will give the keynote address at the annual Lincoln-Thomas Day event to be held Saturday, September 21, 2019 from 12 noon to 2 pm at Fort Stevens, Washington, D.C. The event jointly honors Abraham Lincoln’s signing of the preliminary Emancipation Proclamation on Sept. 22, 1862 and Mrs. Elizabeth Thomas, the free African-American owner of the land that became Fort Stevens (where Lincoln was chastised with “Get down you fool” as he stood in enemy fire on the Fort’s wall). This event is also free to public so please come on down and support me, the National Park Service, and the Military Road School Preservation Trust. More info soon as the organization updates their website.

Beyond that I’m already scheduled to give a talk at a private club in D.C. next April and will be at the annual Lincoln Forum in Gettysburg in November. The Lincoln Group of DC has already scheduled speakers throughout the fall of 2019 and spring of 2020, so check out the Lincoln Group of DC website for more information and join us.

Lincoln’s Rocking Chair – The Ford Museum and Greenfield Village

  By

Abraham Lincoln rocking chairMy Chasing Abraham Lincoln tour took me to Dearborn, Michigan to see the chair. “The Chair.” The rocking chair that Abraham Lincoln was sitting in the moment he was assassinated. The chair is in the Henry Ford Museum of American Innovation, which along with its outdoor venue, Greenfield Village, is a treasure trove for Abraham Lincoln aficionados.

After spending the previous day in the bowels of the Allen County Public Library in Fort Wayne, Indiana, where Emily Rapoza helped me research their incredible Lincoln collection, I drove from Fort Wayne up to Dearborn to see the original rocking chair. After it had languished for decades in storage at the Smithsonian Institution, the aging widow of Ford’s Theatre co-owner Harry Ford reclaimed it in 1929, and it was soon auctioned for $2,400. The buyer? An agent for automobile pioneer Henry Ford (no relation to the Ford’s Theatre Fords). Henry Ford had revered Lincoln, the “humble, self-made man, the ordinary man who seized opportunity and raised himself up.” The Lincoln rocking chair now sits in a temperature and humidity controlled glass enclosure in the Henry Ford Museum.

But there was more Lincoln to the visit. Prior to the protected spot in which it now sits, the chair was held in the Logan County Courthouse in the adjoining Greenfield Village. This is the actual courthouse from Postville, Illinois (since renamed Lincoln, Illinois) in which Lincoln practiced in during his long months on the 8th Judicial Circuit. Ford had it transported to Michigan and restored to depict Lincoln’s visits between 1840 and 1847.

The chilly, rainy day I visited made the warm and dry courthouse a welcome retreat. A somewhat bored docent was happy to see someone he could entertain. Finding a knowledgeable patron, his love for talking about Lincoln cascading out like the water Lincoln saw flowing over the lip of Niagara Falls. I decided not to tell him about my own book about Lincoln and let him run on with an incredible font of information about the courthouse, Lincoln, and legal circuit. He also told me the wardrobe sitting in the corner of the courthouse was believed to have been built by Lincoln’s father, Thomas. The knowledge and enthusiasm the docent exhibited was exhilarating. He was so enthralling I didn’t even tell him I had written a book on Lincoln.

One of my previous books was about Thomas Edison and Greenfield Village also has a replica of Thomas Edison’s Menlo Park lab, including some original outbuildings and even soil carted in by train from the New Jersey site. I had visited the current Menlo Park site museum and its towering lightbulb, as well as his West Orange (NJ) and Fort Myers (FL) laboratories, so it was a great treat to see one of his first labs as it was. Even more exciting, I fortuitously was there during one of the periodic visits by Edison himself, an actor who came into the lab in character and told us all about his current work. Afterwards I toured some old saw and grist mills important for my research.

Lincoln furniture, Ford Museum

Back inside the Ford Museum I found a small center table and side chair once owned by Abraham and Mary Lincoln in their Springfield, Illinois home. Furniture owned by other writers like Mark Twain and Edgar Allan Poe were a thrill to see. I also spent some time in the Agriculture section of the museum where I could see some of the technological improvements (e.g., a McCormick reaper) that I’m researching for my next Lincoln book. For the science geek in me they had a Mathematica section with all sorts of cool exhibits.

Both the Museum and the Village have much more worth seeing and I highly encourage everyone to make the trip. There truly is something for everyone here and one can’t help but learn some history and science while being entertained.

My Chasing Abraham Lincoln tours continue! Much more to come.

Seeing the Real Cuba – Camagüey

  By

American travel to Cuba has been restricted since the early 1960s, although some Americans have visited the capital city Havana on cruise ship stops. But Havana is no more the real Cuba than Paris is the real France. To really understand the nation you must get out to the country, which includes Camagüey, roughly 350 miles east of Havana.

Camagüey is actually the third largest city in Cuba with its 325,000 inhabitants. Unlike the more cosmopolitan Havana, Camagüey retains its deep Spanish influence. The city also retains the charm – and tendency to get lost – in its winding, narrow streets. As we discovered during our three days there, Camagüey’s old town area is a maze of blind alleys and small squares with small streets leading off in many directions. We visited several of the squares, starting with the one right outside our quaint hotel, as well as to the outlying countryside to visit farms.

Camaguey, Cuba

Local mythology claims that the confusion caused by this maze was intentional as a means of getting invaders hopelessly lost in the city, but in reality it probably is just a lack of central planning.

In Camagüey and environs we visited with many local artists including Pepe Gutierrez (beautiful work in leather), the Casanova family (potters), Ileana Sanchez and Joel Jover (eclectic painters), and Martha Jimenez (sculpture and painting). Each gave us an exhibition of their work, then answered our sometimes insightful, sometimes clueless questions. Usually this was through translation by our local guide since most Cubans outside Havana are as monolingual as most Americans.

We also got a sense of the realities of food distribution in this centrally controlled communist economic system. A visit to an outlying dairy farm gave us a first hand look at cow milking and horse shoeing, but also the knowledge that all the milk produced is sold to the government (except for some held for personal family use). Farmers aren’t allowed to sell directly to the public. Instead the raw milk is sent to the government, which has it pasteurized in a government-approved plant and then redistributed back to the people. The same process is used for other commodities such as rice, chicken, wheat, eggs, etc.

Which gets us to the ration stores. In Camagüey and the other small towns we stopped in it was common to see groups of people milling around outside. Some of this was to capture any breeze as air conditioning is essentially non-existent outside the tourist hotels (indeed, many places don’t have running water or electricity much of the day). But crowds also gathered at ration stores that were expecting a shipment of chickens or eggs or bread, surging in with their ration books to get their allocated portion before the supply ran out. When we were there the country had been suffering under a grain shortage, which meant a lack of not only bread but feed for chickens, and subsequently also a shortage of eggs. Even when you could get these commodities, the amount allocated to each family was extremely limited (e.g., a few eggs for a family for the week).

While the central collection and distribution system is inherently inefficient and prone to corruption, much of the chronic shortages are due to two factors: 1) Cuba is an island and can’t produce enough food to meet its needs (about two-thirds of the rice eaten is imported, a stunning fact for a nation in which rice and beans is the base dish at every meal), and 2) the ongoing (and now expanded) U.S. embargo, which blocks any U.S. direct trade with Cuba as well as effectively blocking trade from other countries by penalizing those foreign businesses that try to do business with Cuba.

If all you see of Cuba is Havana you’ll walk away with a false perception of the island. One obvious example is reflected in the hundreds of “classic cars” used as taxis to shuttle tourists around the capital city. In reality, there is only 1 car for every 167,000 Cubans. What cars they have are cobbled together and unreliable, as is the availability of gasoline (or homemade oil) needed to keep them running. Travel by ox or horse cart, or by bicycle or pedicab (one of our regular forms of transportation in Camagüey and elsewhere), is more the norm, as is walking. A lot of walking. Oh, and the big ritzy western-style Hotel Nacional in Havana is a huge contrast to the tiny, more humble, adobe abodes in which most Cubans – including those with professional jobs like psychologists and hotel managers – live (pay rates are also strictly controlled by the government).

I traveled on one of the “people-to-people” tours with Road Scholar that take advantage of an exemption in the embargo. With the recent administration edict further restricting travel, I’m not sure whether these programs can still run. If they can, I highly recommend going to Cuba and getting out to the towns and countryside far away from Havana where you can learn a little more about the real Cuba.

Chasing Lincoln’s Almanac Murder Trial in Beardstown

  By

On my most recent Chasing Abraham Lincoln trip I stopped in Beardstown, Illinois to visit the site of one of Lincoln’s most famous cases – the Almanac Murder Trial. Beardstown has the only active courthouse that Lincoln practiced in, and the 1858 trial was both sensational and controversial.

Almanac trial

I arrived at the Beardstown Courthouse Museum around 3:50 pm. The sign said it was open only until 4 pm, so I rushed in to find a nearly empty foyer and some locked doors. As my hopes began to fade I encountered a resident volunteer guide named Paula Woods. I felt intrusive as I told her I would like to see the museum, as she fumbled for an old-fashioned keychain reminiscent of a jailhouse. Before we were finished, I actual did see the jailhouse cell that had held Duff Armstrong, the man charged with murder.

Even before she opened up the first door leading to a small room filled with Lincoln and trial-related artifacts, the visit turned into something special. In the foyer Paula pointed out a tall sign highlighting the Abraham Lincoln National Heritage Area and the Looking for Lincoln campaign. I had indeed heard of it, I said, and had in fact just participated in the LEAD: Spirit of Lincoln Leadership Academy program (hence my late arrival to Beardstown). It turns out Paula isn’t just a volunteer, she is the Chair of the Commission that runs the courthouse museum and other historical locations in Cass County. She is also on the LEAD program Board!

The 4 pm closing time quickly sped away as Paula showed me the exhibits and then unlocked the door to the stairs leading to the second floor courtroom. The court is still in session, she explains, with cases heard about once a month. Entering the doorway I was standing in the very court where Lincoln defended Duff Armstrong. The key witness in the trial claimed he clearly saw the fight by “the light of a high moon” around 10 or 11 pm that night. Aha, thought the scientifically minded Lincoln and produced an almanac showing the moon “runs low” that night and was already setting by the time of the incident. Having shown the witness lying, Duff Armstrong was acquitted. On the wall is a large painting depicting the moment Lincoln pointed out the discrepancy to the jury, the almanac clear on this point.

The almanac most often depicted was the Old Farmer’s Almanac for that date, although no one actually knows if it was that one or another of the several available at the time. There is even a suggestion that the almanac was forged, but modern recalculations show the moon would indeed have been unusually low that night, part of an 18.6-year lunar cycle that affects lunar declination.

As people started to show up for a pre-arranged community meeting in the courtroom, Paula took me around other parts of the courthouse, including the jailhouse. It was here that Duff Armstrong spent his days and nights waiting for his trial to start. Lincoln had been friends with the Armstrong family for many years and wrote Hannah Armstrong as soon as he heard about her son Duff’s predicament. Lincoln refused payment, citing his work as thanks for all the favors done by the Jack and Hannah over the many years of Lincoln’s life.

Long after the official closing time I thanked Paula for staying late on my behalf. We discussed the work of the LEAD program and Heritage Area, as well as how my book has successfully brought Lincoln to a broad swath of the American public. Having started the day with the LEAD students, it was time to head north for more adventures Chasing Abraham Lincoln.
