Brown was the man who was responsible for starting the franchise.  On an early June day in 1946, Brown, who operated the Boston Garden arena and was part of the National Hockey League's Boston Bruins, was the driving force behind the Basketball Association of America and the Celtics birth.  After considering several team names, including Whirlwinds, Unicorns and Olympics, Brown opted for Celtics.  He hoped to grab the attention of Boston's large Irish American population.  John Davis "Honey" Russell was hired as the first Celtics coach, and the team soon began its inaugural season, losing its first game 59–53 to the Providence Steamrollers.
