Margaret Osborne du Pont
Margaret Osborne du Pont was born on March 4, 1918. She was ranked number one in the world for women's professional tennis from 1947 to 1950. After giving birth to her son William du Pont, III in 1952, she returned to professional tennis and won nine doubles championships at Wimbledon and the U.S. Open.
While married to William du Pont, Jr., Osborne practiced her game at the indoor tennis court at the Bellevue estate. With her husband's help, she was able to bring the game of tennis to local northern Delaware parks and schools with instruction programs and tennis court construction projects.
