He developed the sorting algorithm quicksort in 1959/1960. He also developed Hoare logic for verifying program correctness, and the formal language communicating sequential processes (CSP) to specify the interactions of concurrent processes (including the dining philosophers problem) and the inspiration for the occam programming language. Question: What type of programming language was created by Tony Hoare and can be seen implemented in the Elliot ALGOL complier?  Answer: occam programming language
