Grand Slam (tennis) champions in men's doubles

John Donald Budge (June 13, 1915 – January 26, 2000) was an American tennis player. He is most famous as the first tennis player — male or female, and still the only American male — to win the Grand Slam, and to win all four Grand Slam events consecutively overall. Budge was the second man to complete the career Grand Slam after Fred Perry, and remains the youngest to achieve the feat. He won ten majors, of which six were Grand Slam events (consecutively, a men's record) and four Pro Slams, the latter achieved on three different surfaces. Budge is considered to have one of the best backhands in the history of tennis, with most observers rating it better than that of later player Ken Rosewall.Budge is also the only man to have achieved the Triple Crown (winning singles, men's doubles and mixed doubles at the same tournament) on three separate occasions (Wimbledon in 1937 and 1938, and the US Championships in 1938), and the only man to have achieved it twice in one year. Budge was the world Number 1 amateur in 1937 and 1938 and world Number 1 professional in 1939, 1940 and 1942.

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.
