Together with his Harvard classmate, Beals Wright, Edgar Leonard took the 1904 Olympic doubles title, losing only one set in the four matches they played. In the singles that year, Leonard lost in the semi-finals to the eventual runner-up, Robert LeRoy. Leonard graduated Harvard in 1903 after having captained the tennis team and having shared the intercollegiate doubles title in 1902. He never won a national championship, but in 1903 he achieved his highest national ranking of eighth. Leonard became a very successful businessman in a number of different fields. After college he helped his father run the family wool business, but in 1915 Leonard settled in New York, where he helped establish the brokerage firm of Moore, Leonard, & Lynch. This was his primary occupation for the rest of his life although he served on the board of several companies. During these years Leonard occupied his leisure hours with court tennis and polo.
