What it is

Simula I (1962-1965) was created to simulate systems, and Simula 67 added classes, objects, inheritance and virtual procedures. It was the origin of object-oriented programming.

Dahl and Nygaard received the Turing Award in 2001. The first Simula 67 compiler was finished in 1969.

What it led to

  • Alan Kay's Smalltalk, which took ideas from Simula
  • Stroustrup's C++, inspired by Simula
  • Java, C# and most current languages
