Mavis Batey

Mavis Lilian Batey (née Lever; 5 May 1921 – 12 November 2013) was an English codebreaker during World War II and one of the leading female codebreakers at Bletchley Park.

Batey later became a historian of gardening, who campaigned to save historic parks and gardens, and an author. She was awarded the Veitch Memorial Medal in 1985 and made a Member of the Order of the British Empire (MBE) in 1987, in both cases for her work on the conservation of gardens.
