== Biography ==
'''Anders Hejlsberg''' is a Danish software engineer who co-designed several popular programming languages and development tools. He is best known as the original author of [[Turbo Pascal]] and the chief architect of [[Delphi (programming language)|Delphi]] and [[C Sharp (programming language)|C#]].

Hejlsberg studied engineering at the Technical University of Denmark but left before completing his degree to work on software. In the early 1980s, he wrote a Pascal compiler for the Nascom microcomputer, which later became the commercial product Turbo Pascal. That compiler was acquired by [[Borland]] in 1983, and Hejlsberg joined the company. At Borland he led the development of Turbo Pascal and later created Delphi, a rapid application development environment using Object Pascal.

In 1996, Hejlsberg moved to [[Microsoft]], where he initially worked on [[Visual J++]] and the [[Windows Foundation Classes]]. He then became the lead architect of the [[C Sharp (programming language)|C#]] programming language, which debuted in 2000 as part of the [[.NET Framework]]. Hejlsberg has continued to guide the evolution of C# through versions 2.0 to the present, and also contributed to the design of [[TypeScript]], a typed superset of JavaScript.

== Contributions ==
Hejlsberg's work has been influential in both the early microcomputer software industry and the modern enterprise software landscape. His key contributions include:
* Creating the first widely used integrated development environment for Pascal (Turbo Pascal).
* Pioneering component-based rapid application development with Delphi.
* Designing C# as a modern, object-oriented language that combined features from C++, Java, and Delphi while introducing innovations such as LINQ and async/await.
* Helping to define the [[Common Language Infrastructure]] (CLI) standard.

== Awards ==
Hejlsberg has received multiple industry awards, including the Dr. Dobb's Excellence in Programming Award in 2001 and being named a Microsoft Technical Fellow. He was inducted into the Computer History Museum's Hall of Fellows in 2015.
