Simula

   The SIMULA programming language was designed and built by Ole-Johan
   Dahl and Kristen Nygaard at the Norwegian Computing Center (NCC) in
   Oslo between 1962 and 1967. It was originally designed and
   implemented as a language for discrete event simulation, but was
   later expended and reimplemented as a full sacle general purpose
   programming language. 
   
   [...]

   Although SIMULA is an extension of the programming language ALGOL 60,
   it is not a true extension of it. SIMULA retains the spirit of ALGOL
   60 and includes that language as a subset, except for some minor
   exceptions.

   [...]

   Although SIMULA never became widely used, the language has been
   highly influential on modern programming methodololy. Among other
   things SIMULA introduced important Object-Oriented programming
   concepts like classes and objects, inheretance and dynamic binding.
