The team announced Wednesday that Attles passed away at his home in East Bay, Calif., surrounded by family.
“Alvin leaves behind a profound legacy within the game of basketball and the Bay Area community, but especially as a family man and humanitarian,” the Warriors said in a statement. “We mourn his loss alongside his wife, Wilhelmina, son Alvin, and all who knew and loved him.”
Attles began his NBA career as a fifth-round pick of the then-Philadelphia Warriors in 1960. On March 2, 1962, in Hershey, Pa., he had 17 points against the New York Knicks on a night where teammate Wilt Chamberlain scored 100 points.
He moved with the franchise to San Francisco later in 1962 and remained a player through the 1970-71 season, finishing with career averages of 8.9 points, 3.5 rebounds and 3.5 assists in 711 games.
Attles served as the Warriors’ player-coach during his final season and remained the head coach through 1983, leading them to the NBA championship in 1974-75. They swept the then-Washington Bullets in the NBA Finals, making Attles the second Black coach to win a title after Bill Russell.
Attles compiled a 557-518 record as the Warriors’ head coach. He later served as the team’s general manager for three seasons, returned as an assistant coach in 1994-95 and also worked in the front office as a vice president and consultant, ultimately spending more than six decades with the organization.
“Alvin Attles had a huge, positive influence on me and my career, not just drafting me in 1985 and bringing me to the Bay Area but guiding me through my journey as a player and a young man, both in good and difficult times,” former Warriors star Chris Mullin said.
“He was a dear friend, mentor and role model and someone I admired tremendously and tried to emulate. He set the standard for all of us when it comes to integrity and humility and was truly a champion both on and off the court.
Attles was inducted into the Naismith Memorial Basketball Hall of Fame in 2019. His jersey No. 16 was retired by the Warriors.
