Françoise Dürr

Françoise Dürr (born 25 December 1942; sometimes referred to by English writers as Frankie Durr) is a retired French tennis player. She won 50 singles titles and over 60 doubles titles.

Durr played with an unorthodox backhand, which she played with an Eastern forehand grip and her index finger extended up the handle. She is also noted for having an unorthodox serve that "might not have registered on a radar gun" according to her official Tennis Hall of Fame biography.

According to Lance Tingay, Bud Collins, and the Women's Tennis Association, Dürr was ranked in the world top ten from 1965 through 1967, from 1970 through 1972, and from 1974 through 1976, reaching a career high of world No. 3 in those rankings in 1967. She finished second to Billie Jean King in prize money earnings in 1971.

Dürr reached a total of 27 Grand Slam finals – one in singles, 18 in women's doubles, and eight in mixed doubles. She won twelve of them.
