I first learned Pascal around 1978, tried Microsoft's QuickPascal around 1990, then used Turbo Pascal for work on a planetary science simulator [0] and teaching. From 1995 on I used its successor, Object Pascal and Delphi, which I thought was a really powerful combination of a good language, libraries/frameworks, and IDE. Mostly for the PC, Borland tried briefly to market to Unix systems with Kylix, but it didn't gain as much traction as they would've liked, I guess. Anders Hjelsberg [1] was inspired by Wirth's Tiny Pascal in his Algorithms + Data Structures = Programs book to work on Pascal. I think his efforts on Turbo Pascal, and Object Pascal were truly inspired.
