The daughter of the director of a Northampton shoe manufacturer, Elizabeth Church was swimming from the age of eight. She won a senior 200 yards breaststroke title at Peterborough, when barely 16-years-of-age, and followed that with successive ASA titles in 1947 and 1948. She was selected for the 1947 European Championships in Monte Carlo, and the London Olympics the following year, when she finished sixth in the 200 m breaststroke. At the 1950 British Empire Games, she won two medals, a silver in the 3 x 100 yards medley relay with Helen Yate and Margaret Wellington, and a bronze in the individual 220 y breast. In 1961, Church married Claude Still.
