Thomas Midgley Jr.

Thomas Midgley Jr. (1889–1944) was an American engineer and chemist who contracted polio at the age of 51, leaving him severely disabled. He devised an elaborate system of ropes and pulleys to help others lift him from the bed. He was accidentally entangled in the ropes of the device and died of strangulation at the age of 55. However, he is more famous—and infamous—for two of his other inventions: the tetraethyl lead (TEL) additive to gasoline, and chlorofluorocarbons (CFCs).
