Every nutjob in the world with some out-there theory thinks he's Galileo, rejected for daring to think different. Virtually all of them are, in fact, simply insane.
Yet, there have been brilliant rebels who put their own world-changing ideas on the line, only to end up like Doc Brown in his alternate timeline: humiliated, ridiculed, ignored and/or straight driven to insanity.
You probably know Mendel as the guy who pioneered the science of genetics, and for keeping eighth-graders busy while science teachers watch porn at their desks. Anybody with a high school diploma has filled out those dominant/recessive trait Punnett squares ...
Be honest. How many of you had this explained by a PE coach?
... though astute readers are probably wondering why that technique is called a Punnett square if it predicts patterns Mendel discovered.
What you probably didn't know was that before making his revolutionary discovery, Gregor Mendel flunked his ass out of school and resigned himself to a quiet life as the abbot of a monastery. It had an extensive experimental garden and there Mendel patiently spent the next seven years of his life breeding and cross-breeding peas.
He also hosted a ton of cocaine orgies, but who wants to hear about that?
He carefully documented his work and developed what would eventually be known as Mendel's Laws of Inheritance. Then he wrote it up and got it published in an lesser-known journal, the Journal of the Brno Natural History Society in 1866.
His Genius Was Rewarded By ...
A quiet life of complete anonymity. Mendel's work was read by about zero people, even after he took it upon himself to contact the highest minds of his time by personally sending them copies of his theory. It turns out he would have been better off writing it on a paper bag filled with dog shit and leaving the whole flaming mess on porches.
Why did they ignore him? Because the greatest minds of his time couldn't understand him. It wasn't until 16 years after his death that three independent botanists rediscover Mendel's work and started the genetics ball rolling.
We've brought up poor old Semmelweis once before, but just in case you don't have a running loop of Cracked articles going through your head, here's the recap: Back in 1847, Semmelweis found himself in charge of two maternity clinics. The first clinic was a teaching school, with medical students learning birthing, autopsying and everything in between. The second clinic was intended for women who couldn't afford health care and was serviced by midwives, not actual doctors or students.
His ear-hair acted as attending physician.
Yet it was the second clinic that women of all social statuses begged to get into. Why? Because if they went to the first clinic they'd have a 10 percent chance of dying of puerperal fever, a six percent greater rate of death than in the midwife-run hospital. Women literally had a better chance of surviving a birth on the street than in the first clinic. After an exhaustive study, Semmelweis figured out that medical students were smothered in disease cooties from cadavers, and that maybe, just maybe, they should wash their hands in between the autopsy room and the birthing rooms.

He insisted students perform a simple chlorine wash after handling dead guys and immediately got the death rate down to one to two percent. With numbers like that, you'd think the whole continent of Europe, much less the medical community, would have crowned him "king of live babies" or something.
His Genius Was Rewarded By ...
First dementia, then a beatdown at an insane asylum, then death, by virtually the same disease he had eradicated in his own hospital.
Semmelweis didn't just have the disregard of his contemporaries, he had their flat-out scorn. Maybe it was because he didn't get around to explaining himself on paper right away, so no one understood what hand-washing had to do with keeping people alive. Some doctors were actually insulted that he was accusing Viennese medical students being dirty enough to kill people.
Within 14 years of his groundbreaking discovery, Semmelweis just stopped giving a fuck. He got drunk all the time and called all his detractors "ignoramuses" and "murderers." He started chilling with prostitutes and lashing out at family. That last part proved to be a bad move, because in 1865 they had him committed to an insane asylum, where he was promptly beat up and stuck in a dark cellar.

He died two weeks later. It took another 20 years and Louis Pasteur's germ theory for the rest of the world to come around to the concept of washing your hands to keep from getting sick.
