Admired for her incomparable sportsmanship as well as for her unforgettable volleys, Margaret Osborne duPont (b.1918) ranks among the top Grand Slam champions with 37 titles. Beginning in 1942, duPont joined forces with Louise Brough to form 'the greatest of the great' in doubles pairings. The two friends also treated fans to the longest women's singles match in the history of the U.S. championship, a 4-6, 6-4, 15-13 marathon in 1948 which was finally won by duPont.

For her longtime contributions to the game of tennis as a volunteer, coach, teacher and writer, duPont was honored with both the USTA's Service Bowl and the Educational Merit Award. In 1966 duPont moved to El Paso, Texas where she attended college and joined former doubles partner, Margaret Varner Bloss, in a highly successful second career raising thoroughbred racehorses.
