Walt, known as "Big Bell", left Indiana University with the most rebounds in a career with 1,088 in only 70 games, while averaging 15.5 a game. Averaging 20.5 points a game and shooting 51.7 percent from the floor, Bellamy was named an All-American in both his junior and senior year.
Bellamy was the starting center on the gold medal-winning American basketball team at the 1960 Summer Olympics. Ten of the twelve college players on the undefeated American squad went on to play professionally in the NBA, including fellow Big Ten player, Terry Dischinger, and future Hall-of-Famers in Jerry West, Oscar Robertson, and Jerry Lucas.
Bellamy had a stellar 14 year career in the NBA and was the NBA first overall draft pick in 1961. Bellamy was named the NBA Rookie of the Year in 1962 after having arguably one of the three greatest rookie seasons in NBA history (along with Wilt Chamberlain and Oscar Robertson). His 31.6 point per game average that season is second all-time for a rookie to Wilt Chamberlain's 37.6, and the 19.0 rebounds per game he averaged that season is third best all-time for a rookie (to Chamberlain and Bill Russell). Bellamy also led the NBA in field goal percentage in his rookie season, and had a 23 point 17 rebound performance in the 1962 NBA All-Star Game.
Due to trades to teams with offset game schedules during the 1968-69 season, Bellamy set the still-standing record for NBA games played in a single season with 88.
Bellamy ended his NBA career with 20,941 points and 14,241 rebounds. Bellamy was elected to the Naismith Memorial Basketball Hall of Fame in 1993.
Bellamy is a prominent member of Alpha Phi Alpha, the first intercollegiate Greek-letter fraternity established for African Americans. His half-brother is professional boxer Ron Bellamy. He was notably nicknamed Bells.
