Donald Arvid “Don” Nelson was born in Muskegon, Michigan, and raised in Illinois. After starring at Rock Island High School, he played college basketball for the University of Iowa and earned All-American recognition before beginning his NBA career in 1962.
Nelson played 14 NBA seasons with the Chicago Zephyrs, Los Angeles Lakers, and Boston Celtics. Although he was rarely the biggest star on Boston’s celebrated teams, he became a dependable, intelligent forward whose versatility fit perfectly within the Celtics’ team-first system. He helped Boston win five NBA championships and made one of the defining plays of the 1969 NBA Finals—a late jumper in Game 7 that bounced high off the back rim before falling through. The Celtics later retired his No. 19 jersey.
Immediately after retiring as a player in 1976, Nelson joined the Milwaukee Bucks’ coaching staff and soon became their head coach. Over the next 31 seasons, he coached the Bucks, Golden State Warriors, New York Knicks, and Dallas Mavericks. His teams played an unconventional, fast-paced style that emphasized versatility, smaller lineups, creative mismatches, and freedom for skilled players.
Nelson retired with 1,335 regular-season victories, then the most in NBA history and now (2026) the second-highest total. He was named NBA Coach of the Year three times, led the United States to a gold medal at the 1994 FIBA World Championship, and entered the Naismith Memorial Basketball Hall of Fame in 2012. In 2025, he received the Chuck Daly Lifetime Achievement Award.
Known throughout basketball as “Nellie,” Nelson spent his later years on Maui.
