Abraham Lincoln, Joseph Henry, and Nikola Tesla – Connected by Fate

When Abraham Lincoln took the presidential oath on March 4, 1861, he would become the first president ever to have obtained a patent. Patent Number 6469 was awarded to Lincoln on May 22, 1849 for a device to lift boats over shoals and obstructions. Lincoln writes in his patent 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 had to the accompanying drawings making a part of this specification.

It was the only patent Abraham Lincoln ever received, and the only patent ever given to a President, either before or after their presidency. In contrast, Nikola Tesla had around 300 patents to his name.

Tesla may have had more patents (after all, he was an inventor), but Lincoln always had an interest in invention. During his career as a lawyer he was routinely sought for patent and technologically-dependent legal cases, and during the Civil War he often took matters into his own hands and personally tested some of the biggest technological advances in weaponry. Since he was not classically trained as a scientist – he barely finished one year of formal schooling – Lincoln called on experts to advise him. His biggest scientific adviser during the Civil War was Joseph Henry.

Calling Joseph Henry

Most people likely do not know it, but Nikola Tesla, Thomas Edison, Alexander Graham Bell, Samuel F.B. Morse, Michael Faraday, and others owe their fame, at least in part, to Joseph Henry.

As the Civil War loomed, with Washington D.C. a critical centrality in both the conflict and the potential solution, Joseph Henry was still getting settled into the red sandstone “Castle” that we have all come to know as the symbol of the Smithsonian Institution. The building itself, like the Institution, was relatively new, completed only about six years before Lincoln’s arrival. As the first Secretary of the Smithsonian, and later also as chair of the Permanent Commission to advise the Navy on scientific matters, Henry was one of Abraham Lincoln’s most trusted science advisers. Henry and Lincoln became good friends and worked together to address a wide variety of technological and scientific issues during the Civil War.

So what does Joseph Henry have to do with Nikola Tesla? It turns out, a lot, even though Henry died a few years before Tesla first set foot on American soil.

A precocious child with little interest in formal education, the young Henry stumbled across a book called Lectures on Experimental Philosophy, Astronomy and Chemistry; the book changed his life. Eagerly devouring the scientific principles it contained, Henry began a largely self-taught course in the sciences. Eventually he was taken in by a mentor at the Albany Academy and focused on the nascent field of electricity. Henry excelled in his studies and one day decided to improve upon a weak electromagnet design by William Sturgeon. While the original design used loosely coiled uninsulated wire, Henry wrapped the coils tightly with silk for insulation. The result was four hundred times the original strength. Further improvements led to the powerful electromagnet that became the standard in modern times. This was in 1827, more than fifty years before Tesla came to America.

A few years later, in 1831, Joseph Henry’s innovations led to the first machine to use electromagnetism for motion, effectively, the precursor to the modern direct current motor. It was a simple design, the linear rocking from side to side of a standard electromagnet, but it was the basis for the rotating motion motors eventually designed by Nikola Tesla for his alternating current system. Henry’s simple apparatus allowed him to discover the principle of self-inductance (electromagnetic inductance).

Henry did not stop there. His experiments demonstrated that using an electromagnet in which two electrodes are attached to a battery, winding several coils of wire in parallel worked best. In contrast, if multiple batteries were used, a single long coil was best. This discovery is what made the telegraph feasible.

So why is it we do not hear about Joseph Henry as the father of the electromagnet, or father of the telegraph, or father of self-inductance? In short, Henry was always hesitant to publish any of his work. While he delayed writing up his discoveries, and there were many, others were quick to publish, sometimes after hearing about Henry’s work and “borrowing” it for their own. Famed scientist Michael Faraday, who most credit as the father of self-inductance, actually got at least some of his ideas from a meeting with Joseph Henry; while Henry hesitated, Faraday rushed to publish first. Similarly, Samuel F.B. Morse gets credit for being the father of the telegraph even though it was Joseph Henry’s key discoveries that made it possible; again, after meeting with Henry, Morse took advantage of Henry’s hesitation to publish.

That gets us to Nikola Tesla. Like Thomas Edison and others who developed electric lighting and power in the 1880s and beyond, it was Joseph Henry (and Faraday and others) who had discovered the principles on which the later inventions were based.

In fact, Joseph Henry and Nikola Tesla share yet another claim to fame – both of them have been honored with an international scientific unit (SI). Based on his work with electromagnetic energy, the tesla (T), an SI unit of magnetic flux density and equal to “one weber per square meter,” was named in Tesla’s honor. His forerunner, Joseph Henry, was honored with the SI unit of inductance, the henry (H), for his earlier discoveries in electromagnetic induction.

There are many other connections between Abraham Lincoln and Nikola Tesla, which I discuss in the e-book from which the above is excerpted, Connected by Fate. Joseph Henry, whose early discoveries with electromagnetism, electricity, and the telegraph, became the key principles upon which Nikola Tesla and others made names for themselves years later, was just one connection.

Now Live! Lincoln and Tesla – Connected by Fate

What do our 16th President and a Serbian-born inventor have in common? It turns out, a lot. Abraham Lincoln lived from 1809 to 1865 and led the United States through its darkest years, saving the Union and ending slavery. Nikola Tesla lived from 1856 to 1943 and invented the alternating current induction motor that revolutionized electricity generation. And yet, there are many overlaps in their influences and friends.

Lincoln and Tesla Connected by Fate

Abraham Lincoln and Nikola Tesla: Connected by Fate examines these overlaps. With Lincoln’s interest in science and technology it’s not surprising that the first area of overlap is in the sciences. But there are also connections in the arts, the environment, a World’s Fair or two, and even in the assassination of one of our greatest presidents.

With color photos to highlight the connections, you’ll see how Lincoln’s closest scientific adviser discovered the principles of induction that allowed Tesla to create his greatest invention. You’ll see how Tesla harnessed the power of Niagara Falls, and Lincoln calculated it. You’ll see how Lincoln and Tesla are connected through Mark Twain, and John Muir, and Robert Underwood Johnson. You’ll see how Lincoln’s son Robert was saved by a Booth but became somewhat of an assassination jinx in his own right. And you’ll see much more.

Nikola Tesla and Abraham Lincoln – Connected at the Players Club

Lincoln and Tesla Connected by Fate coverAs I’ve mentioned before, Nikola Tesla and Abraham Lincoln have a surprising number of connections between them. I’m currently writing about them in my new ebook called (unsurprisingly) Abraham Lincoln and Nikola Tesla – Connected by Fate, due out this summer on Amazon.com.

One unexpected, and somewhat ironic, connection revolved around key players in Lincoln’s assassination, at a club called The Players.

During his most socially-active period Nikola Tesla hung out with some of the more famous personages of the time. Among his friends were Samuel Clemens (aka, Mark Twain), John Muir, Robert Underwood Johnson, Sarah Bernhardt, and others. One of his favorite places to relax was The Players, a social club established to “bring actors into contact with men of different professions such as industrialists, writers and other creative artists.” Nikola Tesla was one of those men.

The Players, by the way, was started by famous Shakesperean actor, Edwin Booth. Yes, that Edwin Booth, older brother of the more infamous John Wilkes Booth, assassin of Abraham Lincoln.

Illegitimate son of the world-renowned actor, Junius Brutus Booth, Edwin went on to establish himself as a superior actor on his own. His two brothers, Junius Jr. and John Wilkes, equally illegitimate, also became actors, though one not as famous and the other more infamous. After the assassination, Edwin disowned John Wilkes and eventually resumed acting, making the title role in Hamlet his signature.

Edwin established The Players in 1888 and died in 1893 just as Nikola Tesla was lighting up the “White City” at the Chicago World’s Fair.

There is much more to the story, of course, and I’ll have that in Abraham Lincoln and Nikola Tesla – Connected by Fate. Watch for it on Amazon later this summer.

Abraham Lincoln and Nikola Tesla – Connected by Fate

Nikola TeslaAbraham LincolnAbraham Lincoln was born in Kentucky in 1809, lived in Indiana and Illinois, and was assassinated in Washington, DC in 1865 without ever having left the country. Nikola Tesla was born in 1856 of Serbian heritage in an Austro-Hungarian military outpost in land now part of Croatia. He moved to the United States decades after Lincoln’s assassination and lived for many years in New York City before dying in 1943. Their lives barely overlapped.

Or did they?

I’ve enjoyed a long career as a scientist, during which time I’ve also diligently studied Abraham Lincoln. In 2013 I wrote a book about Nikola Tesla that was published by Fall River Press, an imprint of Sterling Publishing in New York. Tesla: The Wizard of Electricity continues to be a great success, with multiple printings totaling 50,000 copies as of the publication of this e-book you’re reading now. This was followed in 2014 by an e-book, Nikola Tesla: Renewable Energy Ahead of Its Time, that explores in greater depth Tesla’s early interests and promotion of “energy from nature.” While researching both Tesla books I kept seeing unexpected connections between Tesla and Abraham Lincoln. Intrigued, I began a list of separate connections that kept growing beyond my expectations. How could this be?

In fact, it turns out there are surprisingly many connections between these two men. While they understandably never met, their interests and circles of friends and colleagues greatly overlapped. The concept was so intriguing that I put together an e-book exploring many of these connections – friends, acquaintances, professions, and fate. The e-book will be available on Amazon by early summer. I hope you’ll find it as interesting to read as I did to write.

Given Lincoln’s interest in science and technology and Tesla’s life as an inventor, these connections begin with science. But they don’t stop there. Connections between Lincoln and Tesla also exist in the arts, the environment, a great World’s Fair, and yes, even in the assassination of one of our greatest presidents.

So check out Abraham Lincoln and Nikola Tesla – Connected by Fate. While you’re waiting, check out my previous e-book, Nikola Tesla: Renewable Energy Ahead of Its Time on Amazon.com. [If you’ve read it already, please leave a ranking on Goodreads and Amazon]
