When it comes to scientists, brilliance and eccentricity seem to go hand in hand. Some of the most innovative minds in human history have also been the strangest. From eccentric geniuses to the downright insane, here are some of history’s greatest mad scientists.

1. JOHANN CONRAD DIPPEL 

Born in Castle Frankenstein in 1673, Johann Conrad Dippel was a theologian, alchemist, and scientist who developed a popular dye called Prussian Blue that is still used to this day. But Dippel is better remembered for his more controversial experiments. He mixed animal bones and hides together in a stew he called “Dippel’s Oil,” which he claimed was an elixir that could extend the lifespan of anyone who consumed it. He also loved dissecting animals, and some believe he even stole human bodies from Castle Frankenstein. Dippel is often cited as an inspiration for Mary Shelley’s Frankenstein, though the claim remains controversial.

2. GIOVANNI ALDINI 

Another possible Frankenstein inspiration was mad scientist Giovanni Aldini, who among other strange experiments, was obsessed with the effects of electrocution. Aldini, who was something of a celebrity in the early 19th century, travelled Europe, demonstrating the powers of electricity. He was also one of the first scientists to treat mental patients with electric shocks. Though his methods were unconventional, Aldini was well respected in his time, and the emperor of Austria even made him a Knight of the Iron Crown. 

3. WILLIAM BUCKLAND 

Nineteenth century theologian and paleontologist William Buckland was the first person to write a full description of a fossilized dinosaur, which he called the Megalosaurus. But though his work was admired, the early paleontologist had some pretty strange appetites: Buckland was obsessed with trying to eat his way through the entire animal kingdom. He claimed to have consumed mice, porpoises, panthers, bluebottle flies, and even the preserved heart of King Louis XIV.

4. PYTHAGORAS

Anyone who took high school math knows about the Pythagorean theorem. But they might not know that, in addition to being a brilliant mathematician, Pythagoras really hated eating beans. If that sounds more like a personal preference than a mark of madness, consider the fact that he not only avoided eating legumes, but that he went so far as to forbid his followers from eating them as well. It’s unclear where Pythagoras’s bean aversion came from, though some believe Pythagoras saw them as sacred. According to one legend, Pythagoras died when he was being pursued by a group of ruffians, but refused to seek refuge in a nearby bean field. 

5. BENJAMIN BANNEKER 

Eighteenth century engineer, astronomer, and professional tinkerer Benjamin Banneker is believed to have made the first clock built entirely in America. Banneker helped survey the boundaries of the area that would become Washington D.C., charted the stars and planets every night, predicted eclipses, and was one of America’s earliest African American scientists. How did he make time to do all that? By working all night, and sleeping only in the early hours of the morning, of course. The quirky scientist was said to spend each night wrapped in a cloak, lying under a pear tree, meditating on the revolutions of heavenly bodies. Instead of in a lab or office, the astronomer dozed where he could also (potentially) do work: beneath a tree. 

6. ISAAC NEWTON 

One of the most influential scientists in history, Isaac Newton was also one of the quirkiest. The physicist and mathematician was known to experiment on himself while studying optics, even going so far as to poke himself in the eye with a needle. He was also obsessed with the apocalypse and believed the world would end sometime after the year 2060. 

7. LADY MARGARET CAVENDISH

One of England’s first female natural philosophers, Margaret Cavendish was a controversial figure in the 17th century. An outspoken intellectual and prolific writer, she ruffled a few feathers among those who believed women had no place in the scientific community. As a result, Cavendish was often called “Mad Madge.” But though Cavendish wasn’t truly insane, she was more than a little socially inept. On one occasion, Cavendish was “pondering upon the natures of Mankind,” and decided to write down all of the positive qualities possessed by one of her friends on one piece of paper, and on another, all of the woman’s negative qualities. Cavendish then decided to send her friend the list of positive qualities, which she assumed would be appreciated. Unfortunately, Cavendish accidentally sent the wrong list, and received an outraged response from her friend. Cavendish also acted as her own physician, and likely died as a result of her refusal to seek outside medical care.

8. SHEN KUO 

One of the most renowned scholars of the Northern Song Dynasty, Shen Kuo was a master of astronomy, physics, math, and geology, arguing, among other things, that tides are caused by the moon’s gravitational pull and that the Earth and the Sun are spherical, not flat. But he’s also credited as the first writer to describe a UFO sighting. Shen documented sightings of unidentified flying objects in his writing, describing the descent of floating objects “as bright as a pearl.” Nowadays, contemporary UFO theorists have latched onto Shen’s work as the first written record of an alien spacecraft. Shen himself never made that connection: Generally speaking, he was more interested in divination and the supernatural than alien visitors. 

9. TYCHO BRAHE

A great astronomer and an even greater partier, Tycho Brahe was born in Denmark in 1546, and lost his nose in a mathematical disagreement that elevated to a brawl. The scientist spent the rest of his life wearing a copper prosthetic nose. Brahe also threw elaborate parties on his own private island, had a court jester who sat under the table at banquets, and kept a pet elk who loved to imbibe just as much as he did. 

10. MARY ANNING 

Mary Anning was a mad fossil collector: Starting at age 12, Anning became obsessed with finding fossils and piecing them together. Driven by acute intellectual curiosity as well as economic incentives (the working class Anning sold most of the fossils she discovered), Anning became famous among 19th century British scientists. So many people would travel to her home in Lyme Regis to join her on her fossil hunts that after she died locals actually noticed a drop in tourism to the region. But it’s not Anning’s passion for fossils that sets her apart as a slightly mad scientist, but rather the supposed origins of her intellectual curiosity: As an infant, the sickly young Mary was struck by lightning while watching a traveling circus. That lightning strike, according to Anning’s family, was at the root of the once-unexceptional Mary’s superior intelligence. 

11. ATHANASIUS KIRCHER

Sometimes called the “Master of a Hundred Arts,” Athanasius Kircher was a polymath who studied everything from biology and medicine to religion. But Kircher didn’t just study everything, he seems to have believed in everything as well. At a time when scientists like Rene Descartes were becoming increasingly skeptical of mythological phenomena, Kircher believed strongly in the existence of fictional beasts and beings like mermaids, giants, dragons, basilisks, and gryphons.

12. LUCRETIUS

In contrast to Anthanasius Kircher, Ancient Roman poet and scientist Lucretius spent much of his life trying to disprove the existence of mythological beasts. But he employed some truly creative logic to do so. Lucretius is best known for being one of the earliest scientists to write about atoms. But he also argued that centaurs and other mythological animal mash-ups were impossible because of the different rates at which animals aged. A centaur, for instance, could never exist according to Lucretius, because horses age much faster than humans. As a result, for much of its lifespan, a centaur would be running around with the head and torso of a human baby on top of a fully grown horse’s body. 

13. STUBBINS FFIRTH 

While training to become a doctor at the University of Pennsylvania, Stubbins Ffirth became obsessed with proving yellow fever was not contagious. In order to do so, the young researcher would expose himself to the bodily fluids of yellow fever patients. Ffirth never caught yellow fever, though contemporary scientists know that this was not because the disease isn’t contagious (it is), but because most of the patients whose samples he used were in the late stages of the disease, and thus, past the point of contagion. 

14. PARACELSUS 

Renaissance era scientist Paracelsus is sometimes called the “father of toxicology.” But he also thought he could create a living homunculus (a living, miniature person) from the bodily fluids of full-sized people. He also believed in mythological beings like wood nymphs, giants, and succubae. 

15. LEONARDO DA VINCI

Though he’s best known as an artist, Leonardo thought up some pretty amazing inventions. From an early version of the airplane to a primitive scuba suit, Leonardo designed technological devices that are in use to this day. But Leonardo wasn’t your average inventor: He had no formal schooling, dissected animals to learn about their anatomy, loved designing war devices, and recorded many of his best ideas backwards in mirror image cursive, possibly to protect his works from plagiarism.

11 Things You Might Not Know About Neil Armstrong

No matter where private or government space travel may take us in the future, NASA astronaut Neil Armstrong (1930-2012) will forever have a place as the first human to ever set foot on solid ground outside of our atmosphere. Taking “one small step” onto the Moon on July 20, 1969, he inspired generations of ambitious people to reach for the stars in their own lives. On the 50th anniversary of Apollo 11, we're taking a look back at the life of this American hero.

1. Neil Armstrong knew how to fly before he got a driver's license.

Born August 5, 1930 in Wapakoneta, Ohio, Armstrong became preoccupied with aviation early on. At around age 6, his father took him on a ride in a Ford Trimotor airplane, one of the most popular airplanes in the world. By age 15, he had accumulated enough flying lessons to command a cockpit, reportedly before he ever earned his driver’s license. During the Korean War, Armstrong flew 78 combat missions before moving on to the National Advisory Committee for Aeronautics (NACA), the precursor to NASA.

2. Neil Armstrong's famous quote was misheard back on Earth.

When Armstrong and Buzz Aldrin touched down on the Moon, hundreds of millions of television viewers were riveted. Armstrong could be heard saying, “That’s one small step for man, one giant leap for mankind.” But that’s not exactly what he said. According to the astronaut, he was fairly sure he stated, “That’s one small step for a man, one giant leap for mankind.” The “a” may have broken up on transmission or it may have been obscured as a result of his speaking patterns. (According to First Man: The Life of Neil A. Armstrong, Armstrong said, “I’m not particularly articulate. Perhaps it was a suppressed sound that didn’t get picked up by the voice mike. As I have listened to it, it doesn’t sound like there was time for the word to be there. On the other hand, I think that reasonable people will realize that I didn’t intentionally make an inane statement, and certainly the ‘a’ was intended, because that’s the only way the statement makes any sense. So I would hope that history would grant me leeway for dropping the syllable and understand that it was certainly intended, even if it wasn’t said—although it actually might have been.”) Armstrong claimed the statement was spontaneous, but his brother and others have claimed he had written it down prior to the mission.

3. We don't have a really good picture of Neil Armstrong on the Moon.

One of the most celebrated human achievements of the 20th century came at a time when video and still cameras were readily available—yet there are precious few images of Armstrong actually walking on the surface of the Moon. (One of the most iconic shots, above, is Aldrin; Armstrong only appears as a reflection in his helmet.) The reason, according to Armstrong, is that he really didn’t care and didn’t think to ask Aldrin to snap some photos. “I don't think Buzz had any reason to take my picture, and it never occurred to me that he should,” Armstrong told his biographer, James R. Hansen. “I have always said that Buzz was the far more photogenic of the crew."

4. A door hinge may have made all the difference to the Apollo 11 mission.

Theories abound as to why it was Armstrong and not Buzz Aldrin who first set foot on the Moon. (On the Gemini missions, the co-pilot did the spacewalks, while the commander stayed in the craft. For Apollo 11, Armstrong was the commander.) The answer may have been the simple logistics of getting out of their lunar module. The exit had a right hinge that opened inwardly, with the man sitting on the left (Armstrong) having the most unobstructed path to the outside. Aldrin would have essentially had to climb over Armstrong to get out first.

5. Neil Armstrong was more concerned about landing on the Moon than he was walking on it.

The romantic notion of a human stepping foot on space soil captured imaginations, but for Armstrong, it was getting there in one piece that was the real accomplishment. The lunar module Armstrong controlled had to be brought down on the Moon’s surface from 50,000 feet up, avoiding rocks, craters, and other obstacles as it jockeyed into a position for landing. Because there is no air resistance, nothing could slow their descent, and they used thrusters to guide the craft down. That meant there was only enough fuel to attempt it once. The “business” of getting down the ladder was, in Armstrong’s view, less significant.

6. Neil Armstrong was carrying a bag worth $1.8 million.

When Armstrong surveyed the surface of the Moon, he collected a bag of dust for NASA scientists to examine. Apollo moon samples are illegal to buy or sell, but that apparently wasn't the case with the “lunar collection bag” Armstrong used to hold the samples. In 2015, the bag was purchased by Chicago resident Nancy Lee Carlson from a government auction site for $995. But its sale was, apparently, an accident: When Carlson sent the bag to NASA to confirm its authenticity, NASA said it was their property and refused to send it back—so Carlson took the agency to court. A judge ruled it belonged to Carlson, and in 2017, she sold the bag for a whopping $1.8 million at a Sotheby’s auction.

7. Neil Armstrong and his fellow Apollo 11 astronauts had to spend three weeks in quarantine.

When Armstrong, Aldrin, and Michael Collins (who remained behind in the command module while the other two touched down on the Moon) returned to Earth and were fetched by the USS Hornet, they got a king’s welcome. The only asterisk: They had to bask in their newfound fame from inside a sealed chamber. All three men were quarantined for three weeks in the event they had picked up any strange space virus. When President Richard Nixon visited, he greeted them through the chamber’s glass window.

8. Neil Armstrong's space suit was made by Playtex.

Yes, the undergarment people. In the early 1960s, NASA doled out contract work for their space suits to government suppliers, but it was Playtex (or more properly the International Latex Corporation) and their understanding of fabrics and seams that led to NASA awarding them responsibility for the Apollo mission suits. Their A7L suit was what Armstrong wore to insulate himself against the harsh void of space when he made his famous touchdown. The astronaut called it “reliable” and even “cuddly.”

9. Neil Armstrong became a university professor.

Following his retirement from NASA in 1971, Armstrong was reticent to remain in the public eye. Demands for his time were everywhere, and he had little ambition to become a walking oral history of his singular achievement. Instead, he accepted a job as a professor of engineering at the University of Cincinnati and remained on the faculty for eight years.

10. Neil Armstrong once sued Hallmark.

Hallmark was forced to defend itself when Armstrong took issue with the company using his name and likeness without permission for a 1994 Christmas ornament. The bulb depicted Armstrong and came with a sound chip that said phrases like, “The Eagle has landed.” The two parties came to an undisclosed but “substantial” settlement in 1995, which was, according to First Man, donated to Purdue University (minus legal fees).

11. Neil Armstrong was a Chrysler pitchman.

Armstrong’s preference to lead a private life continued over the decades, but he did make one notable exception. For a 1979 Super Bowl commercial spot, Armstrong agreed to appear on camera endorsing Chrysler automobiles. Armstrong said he did it because he wanted the struggling U.S. car maker to improve their sales and continue contributing to the domestic economy. The ads never mentioned Armstrong was an astronaut.

Pioneering Heart Surgeon René Favaloro Is Being Honored With a Google Doodle

Argentinian heart surgeon René Favaloro is the subject of today’s Google Doodle, which features a sketched portrait of the doctor along with an anatomical heart and several medical tools, The Independent reports.

The renowned doctor was born on this day in 1923 in La Plata, the capital of Argentina’s Buenos Aires province, and pursued a degree in medicine at La Plata University. After 12 years as a doctor in La Pampa, where he established the area’s first mobile blood bank, trained nurses, and built his own operating room, Favaloro relocated to the U.S. to specialize in thoracic surgery at the Cleveland Clinic.

In 1967, Favaloro performed coronary bypass surgery on a 51-year-old woman whose right coronary artery was blocked, restricting blood flow to her heart. Coronary bypass surgery involves taking a healthy vein from elsewhere in the body (in this case, Favaloro borrowed from the patient’s leg, but you can also use a vein from the arm or chest), and using it to channel the blood from the artery to the heart, bypassing the blockage. According to the Mayo Clinic, it doesn’t cure whatever heart disease that caused the blocked artery, but it can relieve symptoms like chest pain and shortness of breath, and it gives patients time to make other lifestyle changes to further manage their disease.

Favaloro wasn’t keen on being called the “father” of coronary bypass surgery, but his work brought the procedure to the forefront of the clinical field. He moved back to Argentina in 1971 and launched the Favaloro Foundation to train surgeons and treat a variety of patients from diverse economic backgrounds.

Favaloro died by suicide on July 29, 2000, at the age of 77, by a gunshot wound to the chest. His wife had died several years prior, and his foundation had fallen deeply into debt, which Argentinian hospitals and medical centers declined to help pay, The New York Times reported at the time.

“As a surgeon, Dr. Favaloro will be remembered for his ingenuity and imagination,” his colleague Dr. Denton A. Cooley wrote in a tribute shortly after Favaloro’s death. “But as a man ... he will be remembered for his compassion and selflessness.” Today would have been his 96th birthday.
