Corridon was born in Washington, D.C., but moved with her family to Norwalk, Connecticut, when her father started his medical practice there.

[1] Corridon competed at the 1948 Summer Olympics in London, where she won a gold medal as the lead-off swimmer of the first-place U.S. team in the women's 4×100-meter freestyle relay.

Corridon, together with her teammates Thelma Kalama, Brenda Helser and Ann Curtis, set a new Olympic record in the event final of 4:29.2.

In a very close heat, in an exhausting final sprint, Curtis touched the wall first passing the second place Danish swimmer, and breaking the Olympic record.

She later worked for Avery Brundage, the long-time head of the United States Olympic Committee, and later served as an executive secretary at the Walter Reed Army Hospital.
