Page "David Wheeler (computer scientist)" Paragraph 1

His contributions to the field included work on the EDSAC and the Burrows-Wheeler transform.

Along with Maurice Wilkes and Stanley Gill he is credited with the invention of the subroutine ( which they referred to as the closed subroutine ), because of which jump to subroutine instruction is often called Wheeler Jump.

He was responsible for the implementation of the CAP computer, the first to be based on security capabilities.

In cryptography, he was the designer of WAKE and the co-designer of the TEA and XTEA encryption algorithms together with Roger Needham.
