Which doubles event was added at Wimbledon in 1913 alongside ladies' doubles?

The doubles event added at Wimbledon in 1913 alongside ladies' doubles was mixed doubles.

The 1913 Championships marked the first Wimbledon tournament to stage both a women's doubles competition and a mixed doubles competition. Mixed doubles pairs one male and one female player on each side, making it distinct from the same-sex doubles events.

The inaugural Wimbledon mixed doubles title went to Britain’s Hope Crisp and Agnes Tuckey. They defeated James Cecil Parke and Ethel Larcombe after their opponents retired in the final. The women’s doubles title was won by Dora Boothby and Winifred McNair.

A common mix-up is to confuse the 1913 additions with the tournament’s earlier events. Ladies’ singles was introduced in 1884, while gentlemen’s doubles had already been part of Wimbledon’s programme. Junior and wheelchair doubles are much later additions and were not the events introduced in 1913.
