Poor Inventor Guy!

Bizzare... Thomas Midgley, invented both tetra ethyl lead (TEL) as an anti-knocking agent for petrol AND CFCs for refrigerators. One causes deadly lead poisoning and the other depletes the Ozone layer.
He also invented an apparatus that allowed him to move his limbs while he was bed-ridden by polio towards the end of his life ... the apparatus malfunctioned and killed him by strangulation.

One of the more bizzare facts from 'A Short History of Nearly Everything'
