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.
It was the mid-1970s, three decades after Midgley’s death, before the damage from his two inventions became publicly known. CFCs had punched a hole in the ozone layer over Antarctica; if left ...
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 fuel additive, 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.

Engine knock is caused by a cool flame, an oscillating low-temperature combustion reaction that occurs before the proper, hot ignition. Lead quenches the pyrolysed radicals and thus kills the radical chain reaction that would sustain a cool flame, preventing it from disturbing the smooth ignition of the hot flame front.

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 .
