One year ago today, tennis great Margaret Osborne duPont died at the age of 94. Her name can still be found all over tennis’ record books. DuPont, who was born in Joseph, Ore., on March 4, 1918, still holds the record for most titles at the US Open with 25 -- three in singles, 13 in women’s doubles and nine in mixed doubles. In all, she won six Grand Slam singles titles despite never playing in the Australian Open. DuPont gave birth to a son in 1952 and went on to win nine Grand Slam titles (all in doubles) as a mom. Her final Grand Slam title was in the 1962 Wimbledon mixed doubles playing alongside Neale Fraser. In 1967, duPont was inducted into the International Tennis Hall of Fame in Newport, R.I.
