Playing career

Born in Joseph, Oregon, in 1918, Margaret Osborne grew up on a ranch and learned the game on the public courts of Golden Gate Park in San Francisco. The war, during which she worked at a shipbuilding plant in Sausalito, delayed her first major singles title until the 1946 French Championships, at 28. She won Wimbledon in 1947, married William duPont Jr. the same year, and took the US singles in 1948, 1949 and 1950. Lance Tingay and other British rankers placed her world No. 1 from 1947 to 1950. Of her 37 major titles, 31 came in doubles and mixed, 20 of them with Louise Brough. She won 25 US titles, never played in Australia, was unbeaten in the Wightman Cup and entered the International Tennis Hall of Fame in 1967.

Anecdotes

The person behind the player.

Forest Hills 1948

Bring on the men

Two days before the US final against Brough she learned that her father had died after being hit by a car. Her mother urged her to play. She won 4-6, 6-4, 15-13, and some spectators chanted "Bring on the men!" She and her husband then caught the 8:30 train home to Wilmington.

Wimbledon 1949

43 games without sitting

In the final against Brough the two women played 43 games without a sit-down break. Osborne had four set points in the first set and stood two points from the title at 6-5 in the third, but lost 10-8, 1-6, 10-8. She later said she could not remember ever choking. Brough gently disputed it.

Early years

Too nice to win

Hazel Wightman judged the young Osborne too gentle for a national champion: "She's too nice. She doesn't have the killer instinct." Osborne took no offence. "In a way it was a compliment," she said. "I considered her one of my very best friends in tennis."

Bellevue Hall, Delaware

Ice cream raids

Her husband, a horse breeder, turned his Delaware estate into a tennis venue with eight courts. Pauline Betz remembered up to 36 players living there during tournaments, laundry returned ironed and nightly raids on the ice cream. Of his own game, Osborne said: "He wasn't very good, but he sure loved to play."

Australian Championships

The trip she never made

She never entered the Australian Championships. Her husband expected her to join his January holiday in California, and she recalled that he threatened divorce if she went to Australia, so she never went. Tennis Abstract judged that she would probably have completed a career Grand Slam had she gone.

Wimbledon 1962

A title at 44

Fifteen years after her singles title she returned to Wimbledon as US Wightman Cup coach and won the mixed doubles with Neale Fraser, beating Ann Haydon and Dennis Ralston 2-6, 6-3, 13-11 over 41 games. It was her last major title. Asked about her success, she said: "I just enjoy tennis very much and play the game a lot."
