Chadwick was a typist and swimming coach from California, U.S.A. At 32 years old, she became the first woman to swim the English Channel from England to France in 1951. It is reported that she swum from Cap Gris Nez, France to South Foreland, England in 1950. Her three England-to-France swims each set a record for the fastest time, including her 16 hour 22 minutes crossing in 1951, her 1953 crossing, and her 13 hours 55 minute crossing in October 1955.
On her last three successful swims she also attempted a two-way crossing, but gave up on the return leg on each occasion. In 1952, she also successfully crossed the Catalina Channel in 13 hours 45 minutes. She is tied for 30th on the Oceans Seven list.
