Career Highlights of Anders Hejlsberg
The Development of Turbo Pascal
One of the earliest and most significant highlights of Anders Hejlsberg’s career was the development of the Turbo Pascal compiler in the early 1980s. At a time when personal computing was gaining momentum, there was a growing need for efficient, user-friendly programming tools. Hejlsberg’s work on Turbo Pascal embodied his talent for creating intuitive and high-performance software.
Released in 1983 by Borland, Turbo Pascal quickly became one of the premier tools for software development. This is precisely because of its fast compilation speed, affordability, and user-centered design. Additionally, Hejlsberg’s compiler set a new standard in the industry. Hence, offering a combination of factors that were unmatched at the time. This innovation allowed developers to test and iterate on their programs much more quickly than was possible with existing tools, greatly enhancing their productivity.
Under Hejlsberg’s technical leadership, Turbo Pascal became a beloved tool worldwide. What’s more, it helped to democratize software development by making programming accessible to a much larger audience. Turbo Pascal remained popular throughout the 1980s, with eight versions being released over the decade.

Revolutionary Work at Borland
Following the success of Turbo Pascal, Hejlsberg continued his influential work with Borland by evolving Turbo Pascal into the Borland Delphi environment. In 1995, Delphi was launched, marking another significant milestone in Hejlsberg’s career and in the world of software development. Moreover, Delphi expanded upon his earlier work, combining a robust Object Pascal language with a sophisticated integrated development environment (IDE).
Delphi stood out for its ability to support rapid application development (RAD), allowing developers to build interactive, data-driven applications more efficiently than many of its competitors. With its powerful object-oriented features, Delphi was instrumental in further promoting the use of object-oriented programming techniques. Thus, cementing its position as a major player in the IDE market.
Thanks to tools like Turbo Pascal and Delphi, Borland became a formidable force in the software industry. Besides, his innovations helped shape the way developers approached software engineering, emphasizing quality, speed, and usability.
Contribution to Microsoft: C# and .NET
In 1996, Anders Hejlsberg took on a new challenge by joining Microsoft, where his impact would once again prove transformative. At Microsoft, Hejlsberg became the lead architect of the C# programming language, one of his most renowned achievements. Launched in 2000 as part of Microsoft’s .NET initiative, C# was designed to be a simple, modern, and object-oriented language.
Furthermore, C# quickly gained traction and has since become one of the world’s most widely used programming languages. According to the TIOBE index, which measures the popularity of programming languages, C# consistently ranks among the top languages. As of 2022, it continues to be a preferred choice for building enterprise applications, web services, and video games.
Hejlsberg’s work on the .NET framework further underscored his influence in the industry. By offering a comprehensive and consistent programming model, .NET provided significant benefits to developers, enabling cross-language interoperability and simplifying software deployment. Additionally, this reinforced Hejlsberg’s legacy as a visionary in creating cohesive and flexible software development tools.
