Tennis players at the 1924 Summer Olympics

Helen Newington Wills (October 6, 1905 – January 1, 1998), also known by her married names Helen Wills Moody and Helen Wills Roark, was an American tennis player. She won 31 Grand Slam tournament titles (singles, doubles, and mixed doubles) during her career, including 19 singles titles.
Wills was the first American woman athlete to become a global celebrity, making friends with royalty and film stars despite her preference for staying out of the limelight. She was admired for her graceful physique and for her fluid motion. She was part of a new tennis fashion, playing in knee-length pleated skirts rather than the longer ones of her predecessors, and was known for wearing her hallmark white visor. Unusually, she practiced against men to hone her craft, and she played a relentless predominantly baseline game, wearing down her female opponents with power and accuracy. In February 1926 she played a high-profile and widely publicised match against Suzanne Lenglen which was called the Match of the Century.
Wills had a 180-match win streak from 1927 until 1933. In 1933, she beat the eighth-ranked US male player in an exhibition match. Her record of eight wins at Wimbledon was not surpassed until 1990 when Martina Navratilova won her ninth. She was said to be "arguably the most dominant tennis player of the 20th century", and has been called by some (including Jack Kramer, Harry Hopman, Mercer Beasley, Don Budge, and AP News) the greatest female player in history.

Jean René Lacoste (2 July 1904 – 12 October 1996) was a French tennis player and businessman. He was nicknamed "the Crocodile" because of how he dealt with his opponents; he is also known worldwide as the creator of the Lacoste tennis shirt, which he introduced in 1929, and eventually founded the brand and its logo in 1933.Lacoste was one of The Four Musketeers with Jean Borotra, Jacques Brugnon, and Henri Cochet, French tennis stars who dominated the game in the late 1920s and early 1930s. He won seven Grand Slam singles titles at the French, American, and British championships and was an eminent baseline player and tactician of the pre-war period. As a member of the French team, Lacoste won the Davis Cup in 1927 and 1928. Lacoste was the World No. 1 player for both 1926 and 1927. He also won a bronze medal at the 1924 Summer Olympics.
