Simula

A family of languages developed in Norway in the 1960's and specifically designed to create simulations. Supersets of Algol 60, the Simula languages are notable for being the first object oriented languages in the world and being the predecessor to both SmallTalk and C++, while the object oriented features of Smalltalk over time moved quite a bit away from their Simula origins, C++ retains the object oriented model it inherited in a surprisingly faithful fashion.

Like so many older programming languages Simula used to be spelled with all caps, or SIMULA, however since the ratification of the Simula 87 standard the convention has been to spell it like any other noun, although when referring to classic versions the all caps convention is used , i.e. SIMULA 66 and so on.
