Due to the slow progress of medicine and the lack of "volunteers", scientists and researchers have in the past been forced to experiment on themselves. Some of the experiments were extremely dangerous, and sometimes deadly.
Randolf Lovlis II
The American surgeon investigated the effect of the altitude flight on the body during the Second World War. He had already developed a mask with oxygen scavenger, and watched people lose consciousness after jumping from a plane at a height of 12,000 meters.
Still, he believed that they were weak, so he did the same thing himself and then only recommended wearing a mask.
Max Jozef von Petenfer
A medical researcher from the 19th century believed that the bacterium itself was not enough to cause cholera - a disease that leads to severe diarrhea.
That's why he drank a cocktail of bacteria from the cholera, which he made from the liquid patient's chair. He got ill in 24 hours, but the disease was more mild. He was not sorry because he worked with the goal of "raising awareness about hygiene standards in society".
J.B.S. Hollywood
The British geneticist was known for his "twist", so he drank the sonic acid to see how it works on muscles. The army employed him to treat decompression sickness after diving.
Instead of tracking experienced divers, Holdein himself embarked on an experiment in a special chamber he built, and ended with severe injuries to the spinal cord and punctured bumps. His father and sister worked similarly, and their family motto probably was that without suffering and sacrifice there was no great success.
John Hunter
The famous British physician from the 18th century was also treated by Lord Byron, Benjamin Franklin and King George III. Then the full-blown diseases were an enigma, and he believed that gonorrhea and syphilis were two forms of the same disease.
To prove this, he injected directly into his penis-pus man-infected gonorrhea. Soon the symptoms of gonorrhea and syphilis developed, which apparently proved their claim. What he did not know was that the patient from whom he collected the sample had syphilis without symptoms.
Henri Hed
A British neurologist investigated the recovery of the nerves after damage, and some of his experiments included cutting his own arm and injuring the nerves, so that he would monitor for years how much it took to regain the sensation in his hand.
He did all this because he was not pleased with the reports of patients with the same condition, since they did not know the medical jargon. The second experiment was to immerse the penis alternately in hot and cold water.
Santorio (Santorio Santorini)
The Italian scientist Santorio from the 16th century spent almost 30 years on the scale to study the workings of human metabolism.
He built a huge scales on which he spent most of the day and recorded in detail how much he drank liquids and ate food, and recorded the amount of his big and small necessity. His studies pave the way to the understanding of metabolism, and Santorio is the first man to regularly measure his chair.
