Eugene McDermott
In 1951, McDermott, along with Cecil Howard Green, Patrick E. Haggerty, and J. Erik Jonsson co-founded Texas Instruments. This was done when the company changed its name to Texas Instruments; GSI becoming a wholly owned subsidiary of the new company. This acknowledged that the company had changed its focus from one primarily devoted to oil exploration to one focused on manufacturing. McDermott was the Chairman of TI from 1951-1957, Chairman of the Executive Committee of Board of Directors from 1957-1964 and Director until his death in 1973. During this period of time, Texas Instruments rose to be one of the world's largest corporations.
Cecil Howard Green
In 1941, Green and his partners J. Erik Jonsson, Eugene McDermott and H.B. Peacock bought GSI, a geophysical exploration service. The company began to do electronics work during World War II, and in 1951, the company's name changed to Texas Instruments Incorporated (TI), and GSI became a wholly owned subsidiary of TI.
