William Felton “Bill” Russell is a retired American professional basketball player. He is a five-time winner of the NBA Most Valuable Player Award and a twelve-time All-Star. The 6‘9” Russell was the centerpiece of the Celtics dynasty that won eleven league championships during Russell’s thirteen-year career. Russell holds the record for the most championships won by an athlete in a North American sports league.
Russell also won a gold medal at the 1956 Summer Olympics as captain of the U.S. national basketball team. He is widely considered one of the best defensive players in NBA history. He also served a three-year (1966-69) stint as player-coach for the Celtics, thus becoming the first African American coach in any major American professional sports league. Russell is now a member of the Naismith Memorial Basketball Hall of Fame and the National Collegiate Basketball Hall of Fame. He was named one of the 50 Greatest Players in NBA History in 1996.
