Green met Ida Flansburgh in 1923 while working on his master's thesis at the General Electric Research Center in Schenectady, New York. They were married for 60 years, until her death in 1986.[6]
In 1941, Green and his partners J. Erik Jonsson, Eugene McDermott and H.B. Peacock bought Geophysical Service Incorporated (GSI), primarily a petroleum exploration company.[6] GSI began to manufacture a broader range of electronics equipment and instruments during World War II, including anti-submarine sonar detectors. In 1951 GSI spun off Texas Instruments Incorporated (TI) to pursue the manufacture of a broader range of electronics equipment and instruments, while GSI, now as a wholly owned subsidiary of TI, continued to focus solely on oil exploration services.[6]
Green was vice president (1941–1951), president (1951–1955) and chairman of GSI (1955–1959). He was vice president and a director of Texas Instruments and in 1976 was named an honorary director of the company. He was elected a Fellow of the American Academy of Arts and Sciences in 1970.[7]
In 1978, he was given the inaugural Maurice Ewing Medal of the Society of Exploration Geophysicists, its highest award.
In 1979 Green and his wife were awarded the Public Welfare Medal from the National Academy of Sciences.[8] In 1985, Green received the Golden Plate Award of the American Academy of Achievement.[9]
Cecil Howard Green died in 2003 at the age of 102.[10]
Philanthropy
The growth of Texas Instruments made Green a wealthy man, and he and Ida quickly set about giving his wealth away. The Greens' philanthropic efforts totalled over $200 million, and most of this money was given to education and medicine. He was given an honorary knighthood in 1991 (at age 91) by Queen Elizabeth II.
