Born Althea Louise Brough in Oklahoma City in 1923, she learned the game on the public courts at Roxbury Park in California under the coach Dick Skeen. At 19, in 1942, she reached the final of the US Championships, and she won the title in 1947. When Wimbledon resumed in 1946 she began a run in which she played 21 of the 30 finals across the three events over ten years, winning 13. With Margaret Osborne duPont she won nine US doubles titles in a row from 1942. Tennis elbow and trouble with her service toss slowed her from 1950, but she won Wimbledon again in 1955. She married Alan Clapp in 1958, taught juniors in California for about 20 years, entered the International Tennis Hall of Fame in 1967 and died in 2014.

"She got enormously high bounce on her serve. Women are notoriously feeble in their effort to return it, especially on the backhand."
Anecdotes
The person behind the player.
Eastern grass, 1942
Five in a row at 19
In July and August 1942, aged 19, she won five Eastern grass-court tournaments in a row, then reached the final at Forest Hills, where Pauline Betz beat her. War kept her away from Wimbledon for four more years; when it reopened in 1946, she reached the singles final and lost again to Betz.
All three finals fell on the same day. She beat her doubles partner, Margaret Osborne duPont, 10-8, 1-6, 10-8 in the singles, then went back out for the mixed with John Bromwich and lost in three long sets. By the end she had spent five and a half hours on court.
Her second-round match against Althea Gibson was halted by a lightning storm and finished the next day, when Brough came from 6-7 down in the third set to win 6-1, 3-6, 9-7. Gibson said later that she had "lost all sting" during the delay, and was plain about the result: "Louise beat me."
On her 1950 trip to Australia she developed tennis elbow, perhaps from the wind or a heavy suitcase, and trouble with her service toss began at about the same time. Shirley Fry was saddened to see her tossing the ball up "with a quivering hand." She still won Wimbledon in 1955, beating Beverly Baker Fleitz 7-5, 8-6.
On her debut against Britain in 1946 she won her singles and doubles quickly, the first of 22 Wightman Cup matches she won without a defeat. Her last appearance, in 1956, brought two three-set wins over Angela Buxton and Angela Mortimer.
Gladys Heldman, founder of World Tennis, said she "was very modest and never talked about her tennis." Brough's own verdict on her career was severe: "I just played too long." Remembering the pressure, she said: "All I can think of is how does anyone go through this?"
