Beginning C# 3.0

1.1. A Short History of Object-Oriented Programming (OOP)

Many people believe that OOP is a product of the 1980s and the work done by Bjarne Stroustrup in moving the C language into the object-oriented world by creating the C++ language. Actually, SIMULA 1 (1962) and Simula 67 (1967) are the two earliest object-oriented languages. The work on the Simula languages was done by Ole-John Dahl and Kristen Nygaard at the Norwegian Computing Center in Oslo, Norway. While most of the advantages of OOP were available in the earlier Simula languages, it wasn't until C++ became entrenched in the 1990s that OOP began to flourish.

C was the parent language of C++ and it was often said that C was powerful enough to shoot yourself in the foot multiple times. C++, on the other hand, not only was powerful enough to shoot yourself in the foot, but you could blow your entire leg off without too much difficulty. Most programmers admit that C++ is a very powerful language and it is still in widespread use today. However, with that power comes a lot of complexity. Language developers wanted a simpler and perhaps less complex language for OOP development.

The next step in the development of OOP started in January of 1991 when James Gosling, Bill Joy, Patrick Naughton, Mike Sheradin, and several others met in Aspen, Colorado, to discuss ideas for the Stealth Project. The group wanted to develop intelligent electronic devices capable of being centrally controlled and programmed from a handheld device. ...
