Barry Marshall
Drank bacteria to prove he'd get an ulcer.
Everyone told him that bacteria couldn't survive in the human
stomach. But Barry Marshall, an Australian doctor who had spent his
childhood building fireworks and operating on his pet dog,
had other ideas. Marshall knew that bacteria caused ulcers, and he had watched
his patients make full recoveries after antibiotic therapy.
When he tried to publish his findings, however, the medical fraternity laughed
him out of their conferences.
So Barry Marshall drank some bacteria. In just days, the crippling symptoms of
gastroenteritis began to kick in, and finally confirmed that he was right—and
in trouble. Marshall biopsied his own stomach, isolated the bacteria, wolfed
down some antibiotics, and went on to win the Nobel Prize
in Physiology.
Werner Forssmann
Shoved a
catheter into his own heart.
In 1929, heart surgery was still in its infancy, and physicians struggled to
treat cardiac patients invasively. Werner Forssmann suspected that he could
reach the heart by snaking a hollow tube through his patients' veins, but
colleagues in Eberswald, Germany, told him that the procedure would undoubtedly
prove fatal.
Forssmann begged to differ, and shoved a catheter into his own heart to prove
it.
A nurse agreed to sneak him sterile supplies as long as he promised to perform
the procedure on her instead of on himself. Forssmann agreed, anesthetized his
nurse, and, in one of the greatest switcheroos in medical history, cut into his
own arm and blindly guided the catheter into his heart. Triumphant and still
alive, Forssmann hobbled down to the X-Ray lab to show off his handiwork.
Years later, after he promised never to knock out his nurse and perform surgery
on himself ever, ever again, he received the Nobel Prize in Medicine.
Stubbins Ffirth
Rubbed
vomit in his eyes to show that malaria isn't contagious.
Not every brazen scientist is ultimately vindicated. During the yellow fever
epidemic of 1793, medical student Stubbins Ffirth set out to prove that malaria
is not contagious. He failed.
Ffirth smeared infected vomit into his open wounds, rubbed it into his eyes,
and felt just fine, thank you very much. He went on to sample urine and blood
from malaria patients but never developed the disease.
We now know that malaria is actually quite contagious. So, why didn't Ffirth
get it? Some suspect that Ffirth obtained his vomit from late-stage malaria
patients who were no longer contagious, while others maintain that Ffirth
failed to inject the infected blood directly into his bloodstream. So ol'
Stubbins got lucky—if you call being remembered as that scientist who rubbed
vomit into his eyes lucky.
Thor Heyerdahl
Sailed the
Pacific in a reed boat to prove the ancients had done it.
Thor Heyerdahl was the Norwegian Indiana Jones, an adventurer who studied
biology, geography, and botany, and embarked on wild expeditions to confirm his
archaeological theories. And then he sailed across the Pacific Ocean in a
homemade reed raft.
Heyerdahl had come to suspect that ancient people once sailed the high seas in
tiny reed boats to trade their wares—and their DNA. Mainstream anthropologists
said it couldn't be done, which was Heyerdahl's cue to embark on the ultimate
DIY project. In 1947, Heyerdahl and his team bent reeds into a bare-bones boat,
and together voyaged 4300 miles across the Pacific Ocean in 101 days just to
prove that they could.
Later, in 2011, genetic evidence further reinforced Heyerdahl's hypothesis.
However, most mainstream anthropologists still maintain that linguistic
evidence suggests otherwise, and that the sea stunt had proved nothing.
Tycho Brahe
Lost his
nose in a sword fight over mathematics.
A Danish nobleman who employed midget jesters and owned a pet moose, Tycho Brahe was an eccentric and irascible astronomer, and
what he loved most was arguing about math. At a dinner party in 1566, Brahe
sparked a heated debate over a certain mathematical formula. One guest dared to
disagree with him and, before anyone could stop him, the outraged Brahe
challenged the man to a rapier duel.
Brahe was a deft mathematician but a clumsy swordsman. And so, in the name of
mathematics, he lost the bridge of his nose to a faster fencer. Brahe went on
to exploit many midgets and explore the cosmos as a famous astronomer, but he
did so wearing a prosthetic nose made of precious metals.
August Bier
Tested
anesthesia by beating up his assistant.
Good surgery demands great anesthesia. August Bier, a German physician,
resolved to develop a better anesthetic technique back in 1898. He theorized
that he could inject cocaine into the space around the spinal cord and numb his
patients for surgery without putting them to sleep. Although Bier did test his
spinal anesthesia on a few patients, he decided that the only way he could know
for sure whether it worked would be to test it out on himself.
So Bier asked an assistant to inject liquid cocaine into his spine. But when
the assistant fumbled the procedure, Bier stepped in. He numbed his assistant's
leg and proceeded to beat him up just to see whether or not he could feel the
pain. We're not just talking light pinches and slaps—we're talking cigar burns
and iron hammers to the shins.
In the end, Bier may have lost an intern, but he gained worldwide recognition
as the slightly sadistic father of spinal anesthesia.
Sir Henry Head
Surgically
removed his own nerves to study pain.
Sir Henry Head couldn't figure out how pain worked. A British neurologist with
a fitting surname, Head spent the turn of the twentieth century interviewing
patients with nerve damage about exactly what they felt. But after years of
vague descriptions from disinterested patients, he decided it was time for a
change.
Head called up a surgeon friend and ordered a portion of his radial nerve surgically
removed. Essential motor functions thus severed, Head began to conduct strange
experiments on himself and record his pain in great detail for posterity.
Head's work in pain perception ultimately earned him a knighthood and several
Nobel Prize nominations, and, most importantly, peace of mind. "I shall
know a great deal about pain by the time this is over," he wrote.
George Stratton
Wore
inverted lenses for eight days to prove the brain adapts.

Ever wonder what would happen if you strapped inverted lenses to your face for
over a week? George Stratton, an American psychologist studying sensory
perception in the 1890s, was fairly certain that the brain would correct for
the imbalance and turn the world right side up. But just in case he was wrong,
Stratton decided to give it a try himself.
After four days of living in an upside-down world, Stratton felt sick and
disoriented, but his vision remained inverted. But by day five, his brain began
turning images right side up. By day eight, he could navigate the upside-down
world with ease. But when Stratton finally removed the glasses, the
right-side-up world spun around him, and, until his brain adjusted, he couldn't
tell his right from his left.
Stratton concluded, through headaches and a short hiatus, that the mind is
capable of adjusting the senses to meet environmental pressures—and that the
upside-down world is a less confusing place.
Elsie Widdowson
Starved
herself to develop the minimum wartime diet.
When World War II broke out in Britain, wartime rations left civilians hungry
and concerned about malnourishment. Elsie Widdowson, a dietician and chemist,
resolved to pinpoint her nation's minimum dietary needs but didn't know where
to start. So she stopped eating.
Widdowson subjected herself to a variety of starvation diets and ate only
meager portions of bread, cabbage, and potatoes for several months. Then, just
to prove that her minimum rations could sustain any lifestyle, the starving
scientist hiked trails and climbed mountains nearly every day. Widdowson's
careful records of her overall health throughout the regiment ultimately formed
the backbone of Britain's wartime diet.
Kevin Warwick
Turned his
body into a cyborg prototype.

Kevin Warwick likes robots. A lot. A British scientist and professor of
cybernetics, Warwick felt that robotic research was falling to the wayside. and
so, naturally, he set off to become the world's first cyborg.
Warwick's initial experiments as a cyborg were not terribly ambitious. In 1998,
he had an RFID chip implanted into his arm to interface with simple computers,
turn on lights, and open electronic doors. But by 2002, Warwick had gone full
robot. With electronics, surgery, and pure fearlessness, he tested whether his
nervous system could integrate with a neural interface, and he even tried to
electronically relay his emotions to a fellow cyborg recruit—his wife.
Although the entire project sounds like a dystopia waiting to happen, it's a
relief to see that even in our generation, scientists continue to design wacky
experiments that push the limits. Research is meant to be risky, transgressive,
and unsettling, and Warwick reminds us that there are still scientists out
there who would probably duel to the death to prove a theorem.
