Abraham Lincoln was always interested in technology, so when the Civil War arrived as soon as he was inaugurated, he worked hard to convince the usually conservative military to employ the latest technological advances. One such advance caused him to look to the skies to give every advantage to Union troops. That was the use of balloons in war.
Researcher Charles M. Evans notes that Pennsylvanian John Wise is often credited with being the first American to make significant contributions to the science of ballooning, including atmospheric conditions and construction. He was joined early in the war by James Allen. But it was Thaddeus Lowe who had the most success engaging Lincoln and getting a contract to form an air corps. Lowe hooked up with Smithsonian Secretary Joseph Henry, and on June 11, 1861, they walked over to the White House impressed Lincoln enough to gain his support. Lincoln repeatedly tried to get his first secretary of war, Simon Cameron, and General-in-Chief Winfield Scott to employ Lowe. Lincoln wrote General Scott on July 25, 1861, saying, “Will Lieut. Genl. Scott please see Professor Lowe, once more about his balloon.” When Scott still failed to act, Lincoln reportedly became more assertive, ordering Scott to “facilitate his work in every way.” Lowe eventually fielded a dozen balloons and made over three thousand ascensions using tethered balloons inflated by portable hydrogen gas generators. Lincoln gave Lowe the civilian title of chief aeronaut of the Union Army.
Lowe was an effective self-promoter who knew whose favors to garner. Joseph Henry had gotten him in the front door, Lincoln had gotten him a contract with General Scott, and his greatest use of balloons for reconnaissance was during General McClellan’s Peninsula campaign. To ingratiate himself with McClellan, Lowe put a picture of the general on the back of one of his biggest balloons, the Intrepid. But Lowe used another gimmick—he ran a telegraph line to the tethered balloon to report back in real time enemy troop numbers and movements. To ensure he maintained connection with the highest authority, on June 16, 1861, Lowe lifted his balloon Enterprise up near the White House and sent a telegraph to Lincoln: “This point of observation commands an area near fifty miles in diameter. . . . I have the pleasure of sending you this first dispatch ever telegraphed from an aerial station and in acknowledging indebtedness to your encouragement for the opportunity of demonstrating the availability of the science of aeronautics in the military service of the country.”
There were others who promoted balloons to Lincoln, although he quickly realized that some of them were cranks. Beginning early in 1861 and continuing throughout the Civil War, the prolific Edward L. Tippett sent many letters to Lincoln touting every possible invention, including balloons for warfare. One letter seemed to have caught Lincoln at a bad time in February 1865. In a long rambling letter, Tippett wanted the opportunity to demonstrate to Lincoln “the practicability; by a mathematical problem, easy to understand; of the absolute existence, of a self-moving machine, yet to be developed for the glory of God, and the happiness of the human family.” Unimpressed, Lincoln endorsed the outside of the envelope: “Tippett: Crazy Man.”

As 2024 comes to an end, it’s time to recap how it all went in the writer’s life. At least for this one writer. Once again, it was a busy year, with some residual events related to Lincoln: The Fire of Genius, some new obligations, and some really big news (really!). You can check out my other year-end posts by reading about 
Traveling seems to be done for the year. At least mostly (there might be one short overnight trip squeezed in before New Years). Enough to look back on the year in a traveler’s life. You can see the 
How time flies. The year 2024 is almost over and I think I’ve finished accumulated new books for the year, to it’s time for my annual Abraham Lincoln book acquisitions post. As you’ll quickly see, my goal to reduce the number of books I buy has been relatively successful-the total number of books acquired is definitely fewer-coming in at 25 new acquisitions. Reducing the total number of books? Not so successful. You can read about past years acquisitions by 
On this date, December 11, 1862, Abraham Lincoln transmitted to the U.S. Senate his response to their request that he “furnish the Senate with all information in his possession touching the late Indian barbarities in the State of Minnesota, and also the evidence in his possession upon which some of the principal actors and head men were tried and condemned to death.”
Back in the days when inciting an insurrection against the government was considered disqualifying, on December 2, 1859, abolitionist John Brown was hanged.
Abraham Lincoln’s “few appropriate remarks” at Gettysburg on November 19, 1863, which we now know as the Gettysburg Address (i.e., “Four score and seven years ago today…”) is a major milestone in Lincoln’s historical legacy. Less remembered is that Lincoln was weak and dizzy as he rose to speak, with the symptoms intensifying on the train back to Washington. Back pains developed, and by the fourth day of being bedridden he experienced a scarlet rash, which soon became vesicular. Lincoln had virus-induced smallpox, or at least a less virulent form called variola or varioloid. Over the next three weeks, lesions appeared and worsened, finally drying and peeling. He remained in bed recovering for weeks.
No doubt everyone in the Lincoln world has heard repeatedly about the document we’ve all come to know as the “blind memorandum.” But what about the “reveal party” when Lincoln showed his cabinet what he had written? That event happened on November 11, 1864.
“I am not an accomplished lawyer,” Lincoln wrote in 1850 notes for a law lecture. Continuing in this unpretentious vein, he noted, “I find quite as much material for a lecture in those points wherein I have failed, as in those wherein I have been moderately successful.”
During the U.S. Civil War, there were some who advised Abraham Lincoln to postpone the 1864 election. He refused to do so, saying:
