Mathematician Alan Turing (1912-1954), the decryptor of the Enigma code. Underneath his 1954 portrait Turing's signature and below his quote: "This is only a taste of what is to come, and only a shadow of what is to be". The binary code "10101111l1l10010110011000" inscribed on the converted decimal number reveals Turing's date of birth 23061912 or June 23, 1912.
