Niklaus Wirth was a Swiss computer scientist who designed Pascal, Modula-2 and Oberon, languages known for simplicity and clarity. Pascal became the main teaching language of the 1970s and 1980s. He received the Turing Award in 1984.

Biography

Education

Wirth studied electronics engineering at ETH Zurich, then earned a master’s degree at Laval University in Canada and a PhD at the University of California, Berkeley, in 1963.

Pascal

After work on ALGOL W, Wirth designed Pascal in 1970, named after the mathematician Blaise Pascal. Its clear structure made it the standard language for teaching programming, and Turbo Pascal and Delphi made it popular for personal computer software.

Simple systems

He followed Pascal with Modula-2 and Oberon, and with colleagues built complete workstations, the Lilith and Ceres, designing both hardware and software. His law states that software gets slower faster than hardware gets faster, and he argued for lean, understandable software.

ETH Zurich

Wirth was a professor at ETH Zurich from 1968 until 1999. His book Algorithms + Data Structures = Programs (1976) became a classic. He died on 1 January 2024.
