List of inventors killed by their own inventions

I’m not one for lists, but this one is pretty interesting. For example:

Thomas Midgley, Jr. (1889 – 1944), the inventor of leaded gasoline and chlorofluorocarbons, contracted a severe case of polio, possibly in part due to an immune system weakened by his exposure to lead and other chemicals in the course of his chemistry career. This illness might well have killed him were it not for the pulley-operated system he designed to help move his debilitated body in and out of bed, which entangled him in one of its cords and strangled him to death at the age of 55
