There is long list of inventors whose death was somehow related to the product, process or procedure they invented. To cite just a few,
Marie Curie (1867–1934) invented the process to isolate radium and died of aplastic anemia as a result of prolonged exposure to ionizing radiation.
William Bullock (1813–1867) invented the web rotary printing press. Several years after its invention, his foot was crushed during the installation of a new machine in Philadelphia. The crushed foot developed gangrene and Bullock died during the amputation.
Franz Reichelt, the Flying Tailor This Austrian-born French tailor is remembered for his accidental death by jumping from the Eiffel Tower while testing his own invention, a wearable parachute suit for pilots who would escape from a damaged plane.
Is there a proverb or saying for such a situation?
