Jacques "Toto" Brugnon ([ʒɑːk bʁyɲɔ̃]; 11 May 1895 – 20 March 1978) was a French tennis player, one of the famous "Four Musketeers" from France who dominated tennis in the late 1920s and early 1930s.
He was born in Paris and died in Paris.
He was primarily a doubles specialist who won 10 Grand Slam doubles titles in the French, American, Australian and British championships. Additionally he won two mixed doubles titles at Roland Garros partnering Suzanne Lenglen. He was also a fine singles player but never won a Major title. He played in 20 Wimbledon Championships between 1920 and 1948 and achieved his best singles result in 1926 when he reached the semifinals, losing in a close five set match to Howard Kinsey.
Between 1921 and 1934 he played 31 ties for the French Davis Cup team, mainly as a doubles player, and compiled a record of 26 wins versus 11 losses. He was part of the famous Four Musketeers team that conquered the Cup in 1927 against the USA and of four of the five teams that defended it successfully until 1932.
Brugnon was ranked World No. 9 for 1927 by A. Wallis Myers of The Daily Telegraph.
The Four Musketeers were inducted simultaneously into the International Tennis Hall of Fame in Newport, Rhode Island, in 1976.
