Maria Esther Andion Bueno (born October 11, 1939) is a former professional tennis player from Brazil. During her 11-year career (plus a two-year comeback in 1976-77), she won 19 Major titles (seven singles, 11 women's doubles, one mixed doubles).

In 1960, Bueno became the first woman ever to win all four Grand Slam double titles in one year (three with Darlene Hard and one with Christine Truman Janes).

Bueno began playing tennis at a very young age and, without having received any formal training, won her first tournament at age 12. She was 14 when she captured her country’s women's singles championship.

Joining the international circuit in 1958, Bueno won the singles title at the Italian Championships and the first of her Grand Slam titles, capturing the women's doubles at Wimbledon with Althea Gibson.

The following year, Bueno won her first singles title at Wimbledon, defeating Darlene Hard in the final. She also won the singles title at the U.S. Championships, earning the World No. 1 ranking for 1959 and the Associated Press Female Athlete of the Year award. Bueno was the first non-North-American woman (she is an American - South American - woman) to capture both Wimbledon and the U.S. Championships in the same calendar year. In her native Brazil, she returned as a national heroine, honored by the country’s president and given a ticker-tape parade on the streets of São Paulo.

Darlene Hard (born January 6, 1936, Los Angeles, California, United States) is an American former amateur tennis player. Known for her volleying ability and strong serves, she captured singles titles at the French Championships in 1960 and the U.S. Championships in 1960 and 1961.

With eight different partners, she won a total of 13 women's doubles titles in Grand Slam tournaments. Her last doubles title, at the age of 33 at the 1969 US Open, came six years after she had retired from serious competition to become a tennis instructor. She also played the US Open singles tournament in 1969, losing in the second round to Françoise Durr 6–3, 6–3.

According to Lance Tingay of the Daily Telegraph and the Daily Mail, Hard was ranked among the top ten in the world from 1957 through 1963, reaching a career high of number 2 in those rankings in 1957, 1960, and 1961. Hard was included in the year-end top ten rankings issued by the United States Lawn Tennis Association from 1954 through 1963. She was the top-ranked U.S. player from 1960 through 1963.

Rafael Osuna Herrera (September 15, 1938 – June 4, 1969) is the most successful tennis player in the history of Mexico. He was born in Mexico City, Mexico, and is best remembered for his singles victory at the U.S. Open Championships in 1963, winning Wimbledon Doubles championships twice, the U.S. Open Championships doubles once, and for leading Mexico to its only Davis Cup Final round appearance in 1962. He is the only Mexican to date to be inducted into the International Tennis Hall of Fame, in 1979.

His first successes as an athlete occurred before he was ten years old, when he competed in the open category of the Mexican National Table Tennis Championships. In the course of the tournament, he upset the Mexico City Table Tennis Champion in singles, a feat remarkable both for Osuna's young age and the fact that it was his first tournament. Osuna also won the Doubles Championship, with Alfredo Ramos Uriarte as his partner. From age 10 to 14 he was ranked in the top 10 in Mexico's Open singles in table tennis.
