Fluidr / Polish Memorial by Nick Efford

The success that Bletchley Park had in breaking the German Enigma machines' encryption during World War II was only possible thanks to the initial groundbreaking work of three young Polish mathematicians: Jerry Rozycki, Marian Rejewski and Henryk Zygalski. A memorial - situated beside Bungalow 3, where the first Enigma message of World War II was decrypted - commemorates their vital contribution.
