Robert Edward "Bobby" Billups, Sr. (April 22, 1915 - September 2, 2008) was an American football coach, best known for serving as the head coach of the University of Texas Longhorns from 1949-1974, a period during which Billups transformed the team from a perennial underachiever into one of the best programs in the country, winning four national championships (1966, 1968, 1971, 1972) and dominating the Lone Star Conference from the late 1950's until the early 1970's. While fielding all-white teams for most of his tenure due to political pressure, Billups helped push to integrate the Longhorn athletic department. After the 1974 season, Billups elected to retire prior to his 60th birthday, and was succeeded by his defensive coordinator, Chuck Noll.
