Cecil Howard Green (August 6, 1900 – April 11, 2003) was a geophysicist who trained at the University of British Columbia and the Massachusetts Institute of Technology, and a founder of the company Texas Instruments. With his wife Ida Green , he was a philanthropist who helped found colleges at the University of Texas at Dallas, at Oxford University, and Green College at the University of British Columbia.

Born in Manchester, Britain, Green came to the United States by way of Canada as a child.

He received his Bachelor's degree and Master's degree from MIT in 1923.

On December 6, 1941, Green and 4 others came together to buy a Dallas, Texas based company called Geophysical Service Incorporated (GSI), and in 1951, changed its name to Texas Instruments, which is responsible for the production of calculators, pocket transistor radios (which they were the first to produce) and other electronically controlled machines.

Green served as vice president of Texas Instruments from 1941 to 1951, and as president from 1951 to 1955. It is known that Green's philanthropic efforts total over 200 million dollars, and most of this money was given to charitable organizations involving education and medical affairs. He was given an honorary knighthood in 1991 (at age 91) by Queen Elizabeth II.
