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.
Vannevar Bush
Bush accepted a job with Tufts, where he became involved with the American Radio and Research Corporation (AMRAD), which began broadcasting music from the campus on March 8, 1916. The station owner, Harold Power, hired him to run the company's laboratory, at a salary greater than that which Bush drew from Tufts. In 1917, following the United States' entry into World War I, he went to work with the National Research Council. He attempted to develop a means of detecting submarines by measuring the disturbance in the Earth's magnetic field. His device worked as designed, but only from a wooden ship; attempts to get it to work on a metal ship such as a destroyer failed.
Bush left Tufts in 1919, although he remained employed by AMRAD, and joined the Department of Electrical Engineering at Massachusetts Institute of Technology (MIT), where he worked under Dugald C. Jackson. In 1922, he collaborated with fellow MIT professor William H. Timbie on "Principles of Electrical Engineering", an introductory textbook. AMRAD's lucrative contracts from World War I had been cancelled, and Bush attempted to reverse the company's fortunes by developing a thermostatic switch invented by Al Spencer, an AMRAD technician, on his own time. AMRAD's management was not interested in the device, but had no objection to its sale. Bush found backing from Laurence K. Marshall and Richard S. Aldrich to create the Spencer Thermostat Company, which hired Bush as a consultant. The new company soon had revenues in excess of a million dollars. It merged with General Plate Company to form Metals & Controls Corporation in 1931, and with Texas Instruments in 1959. Texas Instruments sold it to Bain Capital in 2006, and it became a separate company again as Sensata Technologies in 2010.
