Anders Hejlsberg (//, born 2 December 1960) is a prominent Danish software engineer who co-designed several popular and commercially successful programming languages and development tools. He was the original author of Turbo Pascal and the chief architect of Delphi. He currently works for Microsoft as the lead architect of C# and core developer on TypeScript.
Hejlsberg was born in Copenhagen, Denmark, and studied Electrical Engineering at the Technical University of Denmark. While at the university in 1980, he began writing programs for the Nascom microcomputer, including a Pascal compiler which was initially marketed as the Blue Label Software Pascal for the Nascom-2. However, he soon rewrote it for CP/M and DOS, marketing it first as Compas Pascal and later as PolyPascal. Later the product was licensed to Borland, and integrated into an IDE to become the Turbo Pascal system. Turbo Pascal competed with PolyPascal. The compiler itself was largely inspired by the "Tiny Pascal" compiler in Niklaus Wirth's "Algorithms + Data Structures = Programs", one of the most influential computer science books of the time.
In Borland's hands, Turbo Pascal became one of the most commercially successful Pascal compilers. Hejlsberg remained with PolyData until the company came under financial stress and in 1989 he moved to California to become Chief Engineer at Borland. During this time he developed Turbo Pascal further and became the chief architect for the team that produced Delphi, which replaced Turbo Pascal.
Together with Shon Katzenberger, Scott Wiltamuth, Todd Proebsting, Erik Meijer, Peter Hallam, and Peter Sollich, Anders was awarded a Technical Recognition Award for Outstanding Technical Achievement for their work on the C# language in 2007. A video about this is available at Microsoft Channel 9.

- JavaWorld of 1997 writes how Hejlsberg went to Microsoft: Microsoft offered Anders Hejlsberg a signing bonus of US$500,000 and stock options. Microsoft doubled the bonus to US$1,000,000 after Borland made a counter-offer. Hejlsberg left Borland in October 1996.
