Tony Hoare, Inventor of QuickSort, Turing Award Winner
Sir Charles Antony Richard Hoare (Tony Hoare or C.A.R. Hoare, born January 11, 1934) is a British computer scientist, probably best known for the development in 1960 of Quicksort (or Hoaresort), one of the world's most widely used sorting algorithms.
He also developed Hoare logic for verifying program correctness, and the formal language Communicating Sequential Processes (CSP) used to specify the interactions of concurrent processes (including the Dining philosophers problem) and the inspiration for the Occam programming language.
