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.
Kettering and Midgley stated that no alternatives for anti-knocking were available, although private memos showed discussion of such agents. One commonly discussed agent was ethanol. The Public Health Service created a committee that reviewed a government-sponsored study of workers and an Ethyl lab test, and concluded that while leaded gasoline ...

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.
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.

Tellurium has no biological function, although fungi can use it in place of sulfur and selenium in amino acids such as tellurocysteine and telluromethionine. [12] In humans, tellurium is partly metabolized into dimethyl telluride , (CH 3 ) 2 Te, a gas with a garlic -like odor exhaled in the breath of victims of tellurium exposure or poisoning.
