Prescott Sheldon Bush was an American banker and politician. After working as a Wall Street executive investment banker, he represented Connecticut in the United States Senate from 1952 to 1963. A member of the Bush family, he was the father of former Vice President and President George H. W. Bush, and the paternal grandfather of former Texas Governor and President George W. Bush and former Florida Governor Jeb Bush.
Born in Columbus, Ohio, Bush graduated from Yale College and served as an artillery officer during World War I. After the war, he worked for several companies, becoming a minor partner of the A. Harriman & Co. investment bank in 1931. He served in several high-ranking United States Golf Association offices, including president of that organization. Bush settled in Connecticut in 1925.
Bush won election to the Senate in a 1952 special election, narrowly defeating Democratic nominee Abraham Ribicoff. In the Senate, Bush staunchly supported President Dwight D. Eisenhower and helped enact legislation to create the Interstate Highway System. Bush won re-election in 1956 but declined to seek re-election in 1962, retiring from the Senate the following year.
