Marie Curie was a French-Polish physicist and chemist who is famous for discovering a host of new elements, including radium and polonium, as well as the theory of radioactivity and the isolation of radioactive isotopes. She was the joint winner of the Nobel Prize in 1903 (along with her husband Pierre). She died on July 4, 1934, from aplastic anaemia, almost certainly contracted from exposure to radiation. The damaging effects of ionizing radiation were then not yet known, and much of her work had been carried out in a shed without any safety measures. She had carried test tubes containing radioactive isotopes in her pocket and stored them in her desk drawer, remarking on the pretty blue-green light that the substances gave off in the dark.
Thomas Midgley was an American chemist who invented both leaded petrol and CFCs. Though lauded during his time, he has come to be known as having “had more impact on the atmosphere than any other single organism in Earth history” and “the one human responsible for more deaths than any other in history” due to his inventions. He eventually contracted Polio and lead poisoning and was left disabled in his bed. This caused him to create an elaborate system of pulleys and ropes in order to lift himself from bed. He died at the age of 55 after being strangled by one of his pulleys and is notable for the fact that both his inventions, leaded petrol and his pulley operated bed, contributed to his death.
John Godfrey Parry-Thomas was a Welsh motor-racing driver and engineer. He had always dreamed of breaking the land speed record set by Malcolm Campbell, and set about creating a car to do it. He developed a car, named Babs, which had many modifications, such as an exposed chains connecting the wheels to the engines. On the 27th of April 1926, Parry-Thomas broke the existing record, before raising it to above 170 mph the next day. The record stood for a year, before Malcolm Campbell broke it in 1927. On trying to reclaim his record, one of the chains snapped and flew into his neck, partially decapitating him. He died instantly.
William Bullock was an American inventor whose 1863 invention of the rotary printing press helped revolutionize the printing industry due to its great speed and efficiency. Bullock died while trying to repair one of his printing presses, by getting his foot crushed under one of the machines while trying to kick a pulley into place. His foot later became gangrenous, and Bullock died during an operation to amputate his foot.
Otto Lilienthal was a pioneer of human aviation who became known as the Glider King. He was the first person to make repeated successful gliding flights. Newspapers and magazines in many countries published photographs of Lilienthal gliding, favorably influencing public and scientific opinion about the possibility of flying machines becoming practical reality after ages of idle fantasy and unscientific tinkering. On a flight on the 9th August 1896, Lilienthal fell 17 meters, breaking his spine. He died the next day. His final words were, “Small sacrifices must be made!”
