His education was disrupted by World War II, and he completed his sixth form studies at Hanley High School.
[19][20] Wheeler's contributions to the field included work on the Electronic Delay Storage Automatic Calculator (EDSAC) in the 1950s[21] and the Burrows–Wheeler transform (published 1994).
[22] (However, Turing had discussed subroutines in a paper of 1945 on design proposals for the NPL ACE, going so far as to invent the concept of a return address stack.
In cryptography, he was the designer of WAKE and the co-designer of the TEA and XTEA encryption algorithms together with Roger Needham.
In 1950, with Maurice Wilkes, he used EDSAC to solve a differential equation relating to gene frequencies in a paper by Ronald Fisher.
