US Open Flashback: Serena Williams Falls to Jennifer Capriati on Night of Bad Calls

Millions of users, if curious, can google Althea Gibson to find that she was the first player of color of either gender to win a Grand Slam title. Gibson won the French Open in 1956, and the next year she won Wimbledon and the US Open.

In total, Gibson won five majors, but more important, she was a pioneer for her race that eventually inspired the likes of Evonne Goolagong, Arthur Ashe and Venus and Serena Williams to rise to the top of tennis.

64 years ago to the day, Gibson played her first US Open at the age of 23, becoming the first black player of either gender to ever make an appearance at the American Grand Slam.

Althea Gibson passed away nearly eleven years ago, but the legacy of one of America's greatest tennis players—and athletes—is still going strong.
