On January 6, 1945, George Herbert Walker Bush, on leave from active duty in World War II, married former Smith College student Barbara Pierce. The bride was twenty years old—the groom her senior by just one year. George Bush enlisted in the Navy the day he graduated from Phillips Academy in Andover, Massachusetts. Still eighteen when commissioned in June 1943, Bush became the youngest pilot in the United States Navy. Following the war, he attended Yale University and graduated Phi Beta Kappa in 1948.
