With his brother Herman, George R. Brown built Brown and Root Inc. into one of the largest engineering and construction companies in the world. During World War II, a subsidiary firm employed 25,000 people and built 359 ships on the Houston Ship Channel. After the war, Brown and others bought the Big Inch and Little Inch pipelines and founded Texas Eastern Transmission Co. Brown was a friend and supporter of Lyndon B. Johnson and for 15 years was chairman of the board of trustees of Rice University. The Brown Foundation, founded with Herman, has given more than $381 million, mostly to educational and artistic institutions.
