When Humble grew short of capital for expansion, Farish turned to industry executives he had met.
He negotiated with Walter Teagle, head of Standard Oil of New Jersey (later Exxon Corporation), which paid $17 million for a slight majority of Humble in 1919, and Humble gained a market for its oil and financial backing to build in Baytown, Texas one of the world's largest refineries.
In 1926, Farish became a founder and president of the American Petroleum Institute, taking a leadership position in oil conservation.
This jointly owned venture, Ethyl GmbH, was involved with the creation of the Auschwitz labor camp on June 14, 1940, to produce artificial rubber from coal and they also built then operated tetraethyllead plants in Germany.
