American professional basketball player, first to score 20,000 points in the National Basketball Association (NBA). A clumsy player in high school, Pettit turned himself into a graceful 6-ft 9-in (2.06 m) athlete, considered to be the first really agile player of exceptional height in professional basketball.

After graduating from Louisiana State University, Baton Rouge, Pettit played NBA basketball for 11 seasons (1954–65) with the Milwaukee (after 1954–55, the St. Louis) Hawks (Atlanta Hawks). In each season but his last, he led the Hawks in scoring and rebounding. Twice (1955–56 and 1958–59) he was the NBA scoring champion and was voted the league's Most Valuable Player. Pettit led St. Louis to its only NBA championship in 1958 and was named MVP in four All-Star games. On Nov. 22, 1961, he set an NBA single-game record by scoring 19 free throws without missing. In 792 NBA regular season games, Pettit scored 20,880 points (an average of 26.4 points a game) and captured 12,851 rebounds.

He retired in 1965 and was elected to the Naismith Memorial Basketball Hall of Fame in 1970.
