Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
Midgley is unique in having developed two such inventions, but although it’s tempting to see him as an environmental villain, experts say his role was more akin to a cog in the machine.
Founded in 1923, [4] [5] Ethyl Corp was formed by General Motors and Standard Oil of New Jersey ().General Motors had the "use patent" for tetraethyllead (TEL) as an antiknock, based on the work of Thomas Midgley Jr., Charles Kettering, and later Charles Allen Thomas, [6]: 340–41 and Esso had the patent for the manufacture of TEL.
In 1995, leaded fuel accounted for only 0.6% of total gasoline sales and less than 2,000 tons of lead per year. From January 1, 1996, the Clean Air Act banned the sale of leaded fuel for use in on-road vehicles in the United States. Possession and use of leaded gasoline in a regular on-road vehicle now carries a maximum US$10,000 fine in the ...
In his capacity as an engineer with General Motors, Thomas Midgley Jr. experimented with a myriad of different compounds, which he added to petrol in an attempt to prevent engines from knocking. Eventually, he discovered one compound that worked brilliantly: tetraethyllead .

Thomas Midgley Jr. (1889–1944) was an American engineer and chemist who contracted polio at age 51, leaving him severely disabled. He devised an elaborate system of ropes and pulleys to help others lift him from bed. He became entangled in the ropes and died of strangulation at the age of 55.
