Which swimmer simultaneously held the 100, 200, 400, 800 & 1500 m. freestyle world record?

Shane Elizabeth Gould AM, MBE (born November 23, 1956, Sydney, New South Wales, Australia), is an Australian swimmer who won five Olympic medals and set world records in all five freestyle events (100, 200, 400, 800, and 1,500 m.).

She is the only person, male or female, to have ever held every world freestyle record from 100 m. to 1500 m. and 200 m. individual medley world record simultaneously, which she did from 12 December 1971 to 1 September 1972. She is the first female swimmer ever to win three Olympic gold medals in world record time, and the first swimmer, male or female, to win Olympic medals in 5 individual events in a single Olympics.

She is also the only Australian to win 3 individual gold medals at a single Olympics.

At 15 she competed in the 1972 Olympic Games in Munich, swimming 11 races in 8 days, winning gold medals in the 200 m. individual medley, 200 m. freestyle, and 400 m. freestyle, all in world record times. She also won a silver in the 800 m. freestyle and a bronze in the 100 m. freestyle, dominating the women’s swimming field. In 1973 her time in the 1,500 m. freestyle was clocked at 16 min 56.9 sec, setting a world record and making her the first woman to break the 17-minute mark in that event.

Gould’s stroke—two shallow kicks for each cycle of the arms—had long been utilized by distance swimmers but never before by a sprinter. Gould ended her three-year career and retired from competition at age 16.
