quote from article:
"An American mechanical and chemical engineer named Thomas Midgley Jr. was a key player in the development of leaded gasoline (tetraethyl lead) because it was an excellent anti-knock agent, as well as the first chlorofluorocarbons (CFCs) like freon. Midgley publicly defended the safety of tetraethyl lead (TEL), despite experiencing lead poisoning firsthand. He held a 1924 press conference during which he poured TEL on his hand and inhaled TEL vapor for 60 seconds, claiming no ill effects. It was probably just a coincidence that he later took a leave of absence from work because of lead poisoning. (Midgley’s life ended in tragedy: he was severely disabled by polio in 1940 and devised an elaborate rope-and-pulley system to get in and out of bed. That system ended up strangling him to death in 1944, and the coroner ruled it suicide.)"
Can't make this stuff up.
