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.
Mark Shepherd (businessman)
He was hired by Geophysical Service Incorporated in 1948, a company which then focused on the oil and gas drilling industry; GSI subsequently evolved into Texas Instruments. He was one of four engineers sent by the company in 1952 to Bell Laboratories to study the transistor. Texas Instruments licensed the transistor technology that had been invented at Bell Labs in 1947 and pursued applications for its use.
