On February 15, 1934, Swiss computer scientist Niklaus Emil Wirth was born. He is best known for designing several programming languages, including Pascal, and for pioneering several classic topics in software engineering. If there is (or better 'was') one programming language that I really loved in the same way I hated it, then it was Pascal. On the one hand it was a rather easy to understand beginners programming language, but when trying to build 'real world' software projects based on Pascal, most of them in my experience were doomed to fail. The largest project based on Pascal that I was involved with was a 2 mio lines of code near realtime application for the military back in the 1990s. Everybody knew, we better should have chosen Ada or C++, but it was not our decision to use Pascal. Believe me, you wouldn't like to maintain 2 mio lines of Pascal code. Nevertheless, the concept of the language designed by Niklaus Wirth was a great achievement for computer science!
