It also stopped her joining Court, Evonne Goolagong and Kim Clijsters as the only mothers to win Grand Slam titles in the professional era.
Before Saturday, Serena Williams had addressed the crowd after contesting a Grand Slam final 29 times in her career - 23 times as the victor, six as runner-up.
A host of celebrities were out in force at Wimbledon to witness Serena Williams' quest to equal the Grand Slam wins record set by Australian Margaret Court.
Williams has been praised across social media for her performance today, with entrepreneur Everette Taylor writing: 'Serena Williams came back from pregnancy to make it to the finals of Wimbledon at nearly 37 years old.
About 10 months after having a baby, Serena Williams plays in the Wimbledon final against Angelique Kerber.
'Yeah it was such an unbelievable tournament for me, ' Williams said, fighting back the tears.
That motivation was on display during the two weeks she played here. "Honestly, I feel like if I can do it, they can do it", she said.
Williams held to force Kerber to serve it out but the 30-year-old refused to yield.

Returning to major action at the French Open in May, she was forced to pull out of her fourth round match due to a pectoral injury.

Williams - who married Reddit co-founder Alexis Ohanian in November 2017 - was supported from the Royal Box at Wimbledon by her good friend the Duchess of Sussex, who attended the final alongside the Duchess of Cambridge. The fact the German hit 11 total winners to just five unforced errors told its own story. "But now I'm just trying to improve my game, thinking not too much about the results, trying to be a better tennis player, a better person".
