List of inventors killed by their inventions....
William Nelson (ca. 1879−1903), a General Electric employee, invented a new way to motorize bicycles. He then fell off his prototype bike during a test run
Franz Reichelt (1879–1912), a tailor, fell to his death off the first deck of the Eiffel Tower while testing his invention, the coat parachute. It was his first ever attempt with the parachute and he had told the authorities in advance that he would test it first with a dummy.
Max Valier (1895–1930) invented liquid-fuelled rocket engines as a member of the 1920s German rocketeering society Verein für Raumschiffahrt. On May 17, 1930, an alcohol-fuelled engine exploded on his test bench in Berlin, killing him instantly.
The Miami Hurricanes (1984 – 2001) invented swagger. Swagger led them to unprecedented success from a small, private school with no football history to speak of. Unfortunately swagger proved to be to unstable and eventually consumed the program through a series of swagger related issues from Pell Grant scandals to Shapirogate. Other schools since have managed to perfect swagger through disciplined coaching and character kids. Unfortunately for the Hurricanes, the perfect balance came too late and they are dibale for life.
Thomas Midgley, Jr. (1889–1944) was an American engineer and chemist who contracted polio at age 51, leaving him severely disabled. He devised an elaborate system of strings and pulleys to help others lift him from bed. This system was the eventual cause of his death when he was accidentally entangled in the ropes of this device and died of strangulation at the age of 55. However, he is more famous — and infamous — for developing not only the tetraethyl lead (TEL) additive to gasoline, but also chlorofluorocarbons (CFCs)
Marie Curie (1867–1934) invented the process to isolate radium after co-discovering the radioactive elements radium and polonium. She died of aplastic anemia as a result of prolonged exposure to ionizing radiation emanating from her research materials. The dangers of radiation were not well understood at the time.
