Cecil Howard Green KBE (August 6, 1900 – April 11, 2003) was a British-born American geophysicist, electrical engineer, and electronics manufacturing executive, who trained at the University of British Columbia and the Massachusetts Institute of Technology.

The family moved to Vancouver, British Columbia, Canada, where Green attended UBC for two years before transferring to the Massachusetts Institute of Technology, earning both a bachelor's and master's degree in electrical engineering in 1924.

[3][4][5] Green met Ida Flansburgh in 1923 while working on his master's thesis at the General Electric Research Center in Schenectady, New York.

[6] GSI began to manufacture a broader range of electronics equipment and instruments during World War II, including anti-submarine sonar detectors.

[10] The growth of TI made Green an enormously wealthy man, and he and Ida quickly set about giving his wealth away.

One gift was the founding of the Cecil H. and Ida M. Green branch of the University of California Systemwide Institute of Geophysics and Planetary Physics (IGPP).
