Ole-Johan Dahl

Software And Its Engineering

Ole-Johan Dahl was a Norwegian computer scientist who, together with Kristen Nygaard at the Norwegian Computing Center in Oslo, created the Simula programming language in the 1960s. Simula introduced the concepts of classes and objects, and it is widely regarded as the first object-oriented programming language, directly shaping later languages including Smalltalk, C++ and Java. Dahl and Nygaard shared the 2001 Turing Award and the IEEE John von Neumann Medal for this work.

FAQs

What did Ole-Johan Dahl work on before Simula?

His main work at the Norwegian Defence Research Establishment was a high-level language called MAC.

Dahl worked at the Norwegian Defence Research Establishment from 1952 to 1963 in computing and programming, with software development as his main activity from 1956. His main contribution there was a high-level programming language called MAC, used locally during the 1960s. In 1963 he joined the Norwegian Computing Center to work full time on Simula.
