The SIMULA programming language was designed and built by Ole-Johan Dahl and Kristen Nygaard at the Norwegian Computing Centre (NCC) in Oslo between 1962 and 1967.1 It was originally designed and implemented as a language for discrete event simulation, but was later expanded and reimplemented as a full scale general purpose programming language. Although SIMULA never became widely used, the language has been highly influential on modern programming methodology. Among other things SIMULA introduced important object-oriented programming concepts like classes and objects, inheritance, and dynamic binding. Jan Rune Holmevik E-mail: jan@utri.no
