Anders Hejlsberg: Pioneer of Turbo Pascal, Delphi, C# and TypeScript

Anders Hejlsberg, born in 1960 in Copenhagen, showed early talent in programming, learning ALGOL in high school and later developing a Pascal compiler that became Turbo Pascal.

After joining Borland, he led the development of Delphi, which sold over five million copies, before moving to Microsoft in 1996 where he created Visual J++, then the .NET framework and the C# language.

At Microsoft, he also co‑created TypeScript, a typed superset of JavaScript, cementing his influence across decades of software development.
