Wirth designed the programming languages Pascal, Modula and Oberon. His article Program Development by Stepwise Refinement is considered to be a classical text in software engineering. He wrote Algorithms + Data Structures = Programs, which gained wide recognition and is still useful today. He received the Turing Award for the development of these languages. He retired in 1999.
