Turing Award winner Tony Hoare, computing pioneer who invented the Quicksort algorithm for a sixpence bet, dies at the age of 92

Professor Charles Anthony Richard Hoare, known as Tony to friends, has died at the age of 92. One of the greatest programmers in the early history of computing, he invented the Quicksort algorithm after a bet with his boss, later devised Hoare logic (a system for rigorously assessing the correctness of a program), and was the co-designer of ALGOL W, a programming language that would become the basis for Pascal.

Hoare was also a deeply funny, philosophical, and self-deprecating man who had a hundred other achievements to his name.
