How do you celebrate one of the most influential inventors of all time? By remembering the moment he X-rayed his own foot back in 1896, of course. Yes, Nikola Tesla went beyond just electrifying our world (literally) and ventured into a mysterious new scientific frontier that would forever change medicine. And to top it all off? He used his own foot as the guinea pig.
Let’s lace up (pun intended), step back in time, and explore how Nikola Tesla not only experimented with X-rays but also became one of the first pioneers in understanding their immense power and potential dangers.
Nikola Tesla Meets X-Rays
By the turn of the 20th century, Tesla had already left his mark on the scientific world with his groundbreaking work in electromagnetism and electricity. But in 1894, he stumbled upon something curious. During an experiment, he noticed that some of his photographic plates were damaged by what he called “mysterious rays.” Did some scientists lock their lab doors and move on? Sure. But not Nikola Tesla.
Tesla, being Tesla, decided this was worth his time. Little did he know he was entering the same realm as Wilhelm Röntgen, who is often credited as the father of X-rays. Tesla started by developing a high-energy vacuum tube called a “shadowgraph machine,” powered by his very own Tesla coil (his star invention). The vacuum tube emitted rays capable of creating photographic images of bones and dense objects, something no one had seen before.
The first “model” Tesla used to test this radical new idea? Not a stageworthy skeleton or a lab assistant. Nope, it was Tesla himself. He casually popped his foot onto the machine and took what might just be the first X-ray photograph of a human foot in recorded history.
The Iconic Foot X-Ray

Imagine this for a second. You’re Nikola Tesla. You’ve got electricity crackling around you, high-voltage experiments sizzling away, and here you are, casually X-raying your foot. The result? A startlingly clear photograph of his foot bones… and, fun fact, the nails and metal eyelets of his shoe were visible too. Yep, the man captured not only his anatomy but also his shoemaker’s craftsmanship on film.
This photograph, taken in 1896, is not just an impressive exercise of science. It’s also breathtaking proof of Tesla’s relentless creativity and willingness to experiment in ways other scientists hadn’t imagined yet.
Tesla’s Shadowgraphs, Science, and Society

Tesla wasn’t content with merely creating shadowy (but cool) images of feet and hands. No way. He quickly realized the scientific potential behind these mysterious rays. At a time when X-rays were still a novel concept, Tesla was already suggesting that they could revolutionize medical diagnostics.
He recognized how X-rays could be used to:
- Find foreign objects lodged in human bodies (a lifesaver, literally)
- Diagnose diseases like lung infections
- Create clearer insights into human anatomy
Keep in mind, this was coming from a man who X-rayed himself! And to sweeten the deal, Tesla even understood some of the risks of X-rays before many of his peers. He noticed that overexposure caused skin irritation, pain, and even swelling. He was so ahead of the game that he attempted to create an aluminum shield to protect against radiation exposure. Sure, he hilariously misunderstood the safety issue, thinking the rays created nitrous acid rather than what we now know as radiation burns… but still, what an effort, right?
What Could Have Been… If Not for a Fire
Tesla’s work with X-rays might have gotten him the historical credit he deserved if destiny hadn’t thrown in a cruel twist. Just as he was deep into perfecting his shadowgraphs, a devastating fire tore through his New York laboratory in 1895. It destroyed his machines, documents, and much of his life’s work.
It’s heartbreaking to think that Tesla could have outpaced Wilhelm Röntgen in publishing groundbreaking X-ray findings. While Röntgen went on to become the celebrated father of X-rays, Tesla just smiled, congratulated him, and even sent over some of his shadowgraph images.
What a class act.
The Tragic Genius of Tesla’s Later Years
You’d think someone like Nikola Tesla would have had a glorious sendoff in life, right? Well, unfortunately, that wasn’t the case. Despite holding over 300 patents and giving humanity countless innovations, Tesla struggled financially for much of his life. His generosity and obsessive dedication to science left him destitute.
On January 7, 1943, Tesla passed away alone in a New York hotel room at the age of 86. It’s hard to reconcile the image of the man who revolutionized electricity and helped us understand X-rays with someone who died largely unrecognized by the society he helped move forward.
Why Tesla’s Foot X-Ray Still Matters
Tesla may not have gotten the fame he deserved during his lifetime, but his contributions to science and technology continue to shape our world. Beyond his game-changing inventions like alternating current, radio waves, and the Tesla coil, his work with X-rays serves as a reminder of his genius, curiosity, and relentless drive to experiment.
The X-ray of his foot isn’t just a quirky story. It’s a testament to Tesla’s belief in the possibilities of science. Thanks to his pioneering work, the world gained one of its most valuable diagnostic tools. And honestly, can we take a moment to appreciate that his foot photo wasn’t just a selfie, but a scientific marvel?
Whenever we discuss timeless innovations and breakthroughs in radiology, it’s worth remembering the fascinating story of Nikola Tesla and his courageous step into the unknown (pun very much intended). Tesla reminds us that behind every scientific advancement is someone who’s willing to throw caution to the wind… or, in his case, toss his own foot into a homemade X-ray machine.
Hey, science marches forward thanks to people like Tesla. And sometimes, that means literally putting your best foot forward.
