Serena and Venus Williams celebrate gold after winning the Womens Doubles Tennis Final at Olympic Games Sydney 2000 on Sept. 28, 2000 in Sydney.
It was late September 2000, and The New York Times declared it the “Summer of Venus.” Venus Williams had just capped 32 straight wins in tennis with an Olympic gold medal in singles, her smile as big as her forehand.
The next day, after the Olympic doubles tournament concluded with Venus and Serena Williams atop the podium, The Times stated that the Williams sisters had overwhelmed the Olympic medal mix “like a dye drop in a pool.”
Little did newspaper’s editors know then that these descriptors could be used again and again over the next 20 years as Venus and Serena Williams collectively racked up 30 Grand Slam singles titles.
What is mentioned less often is the Williams sisters’ dominance of the doubles game.
Together, they have won 14 Grand Slam doubles titles—two shy of the Bryan brothers, who only played doubles. Nine of these titles were earned at the same Grand Slam tournament where one of them won the singles title as well, and two after they played each other in the final.
The Olympic Games are where the Williams sisters have really made their mark in doubles. While they each hold an Olympic gold medal in singles—Venus from 2000, Serena from the Olympic Games London 2012—they have together won three Olympic doubles tournaments.
This doubles dominance has helped Venus collect five Olympic medals total (four golds, one silver in mixed doubles)—tying her with Britain’s Kitty McKane Godfree for most Olympic medals won by a tennis player, male or female. And Serena is a four-time Olympic gold medalist.
They aren’t done yet. Venus, now 40, has said that she would like to compete in her sixth Olympic Games next summer. Barring injury or retirement, Serena, who just turned 39, is a lead candidate to compete in Tokyo, too.
Here’s a look back at the Williams’ sisters’ Olympic doubles legacy.
