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.
Morris Tanenbaum
In the meantime, Gordon Teal had moved to Texas Instruments, where he was essential to the organization of TI's research department. He also led its team of silicon transistor researchers. On April 14, 1954 he and Willis Adcock successfully tested and demonstrated the first grown-junction silicon transistor. Like Tanenbaum, they used highly purified DuPont silicon. Teal was able to bring the silicon transistor to production. He announced the results and displayed the TI transistors on May 10, 1954 at the Institute of Radio Engineers (IRE) National Conference on Airborne Electronics, in Dayton, Ohio.
