Lawrence Baker, Sr. could play tennis at a high level, and that on-court attitude enabled him to become an outstanding tennis administrator and longtime proponent of the sport. Baker was a National Senior Grass Court Doubles Champion in 1937 and was captain of the United States Davis Cup Team that defeated Canada in 1953. His greater impact on the game was President of the United States Lawn Tennis Association, now known as the United States Tennis Association, from 1948-50. He served as the association General Counsel from 1952 to 1970 and his affection for the court never strayed, serving as a prominent official for nearly four decades. His enduring legacy includes founding the National Tennis Foundation.
