Geoffrey Tandy

Geoffrey A. Tandy (1900-1969) was a British marine biologist and broadcaster.

A friend of T. S. Eliot, he wrote a 'Broadcasting Chronicle' for The Criterion, and was the first to broadcast Old Possum's Book of Practical Cats in 1937. During the war he worked at Bletchley Park, allegedly invited there after the Ministry of Defense confused the word ‘cryptogamist’ with ‘cryptogramist’. At Bletchley his technical expertise allowed him to salvage a waterlogged codebook which helped crack the Enigma code.

Genista McIntosh, Baroness McIntosh is Tandy's daughter by his second wife Maire McDermott.

Tandy’s papers are held at the Natural History Museum.
