Texas Instruments
In 1930, J. Clarence Karcher and Eugene McDermott founded Geophysical Service, an early provider of seismic exploration services to the petroleum industry. In 1939, the company reorganized as Coronado Corp., an oil company with Geophysical Service Inc (GSI), now as a subsidiary. On December 6, 1941, McDermott along with three other GSI employees, J. Erik Jonsson, Cecil H. Green, and H.B. Peacock purchased GSI. During World War II, GSI expanded their services to include electronics for the U.S. Army, Signal Corps, and the U.S. Navy. In 1951, the company changed its name to Texas Instruments, with GSI becoming a wholly owned subsidiary of the new company.
St. Mark's School of Texas
From the school's inception, members of the board focused on creating an endowment and encouraging the study of science. In the 1960s and 1970s, Texas Instruments' co-founders Cecil H. Green and Eugene McDermott donated a math and science quadrangle, the main library, the greenhouse, the planetarium and the observatory.
