Cuthbert Collingwood "Ted" Tinling (23 June 1910 – 23 May 1990), sometimes known as Teddy Tinling, was an English tennis player, fashion designer, spy and author. He was a firm fixture on the professional tennis tour for over sixty years.
He was born in Eastbourne, the son of James Alexander Tinling, a chartered accountant. In 1923, suffering from bronchial asthma, his parents sent him to the French Riviera on doctor's orders. It was there he began playing tennis, particularly at the Nice Tennis Club where the then biggest star of the game, Suzanne Lenglen, would practice. Despite Tinling's youth, Lenglen's father asked him if he would umpire one of her upcoming matches and he would go on to be her personal umpire for two years in between a short career as a player himself. This friendship with Lenglen led him to his first Wimbledon Championships in 1927, where he became player liaison until 1949. During World War II, he was a Lieutenant-Colonel in the Intelligence Corps in Algiers and Germany.
Tinling designed dresses for almost all of the great female players throughout the 1950s, 1960s and 1970s. His dresses were worn by the Wimbledon ladies' champion in 1959, 1960, 1961, 1964, 1969, 1971, 1972, 1973, 1975, 1977, 1978 and 1979. The last Wimbledon champion to wear a Tinling creation was Martina Navratilova in 1979 when she wore his designs to triumph in both the singles and doubles events. In 1983, Billie Jean King wore a Tinling dress in a final for the last time, when she reached the Wimbledon Mixed Doubles final. The last Tinling dress worn at Wimbledon was by Rosemary Casals in 1984, when she lost in the first round. Although he only ever designed dresses for Chris Evert's Federation & Wightman Cup appearances, he designed her wedding dress when she married John Lloyd in 1979. It was a design in 1949 – lace tennis panties (for Gussie Moran) – that led him to being asked to take leave from his position at Wimbledon.
