Simula was created by Ole-Johan Dahl and Kristen Nygaard at the Norwegian Computing Center to simulate discrete-event systems. It introduced the class concept, object instantiation, and inheritance — every OOP language from C++ to Java descends from Simula’s ideas. Bjarne Stroustrup cited Simula as the primary inspiration for C++.
