2011: Simon Peyton Jones and Simon Marlow - GHC

The cash prize is being donated to haskell.org

Simon Peyton Jones and Simon Marlow receive the SIGPLAN Software Award as the authors of the Glasgow Haskell Compiler (GHC), which is the preeminent lazy functional programming system for industry, teaching, and research. GHC has not only provided a language implementation, but also established the whole paradigm of lazy functional programming and formed the foundation of a large and enthusiastic user community. GHC's flexibility has supported experimental research on programming language design in areas as diverse as monads, generalized algebraic data types, rank-N polymorphism, and software transactional memory. Indeed, a large share of the research on lazy functional programming in the last 5-10 years has been carried out with GHC. Simultaneously, GHC's reliability and efficiency has encouraged commercial adoption, in the financial sector in institutions like Credit Suisse and Standard Chartered Bank, and for high assurance software in companies like Amgen, Eaton, and Galois.

A measure of GHC's influence is the way that many of the ideas of purely functional, "typeful programming" have been carried into newer languages and language features. including C#, F#, Java Generics, LINQ, Perl 6, Python, and Visual Basic 9.0. Peyton Jones and Marlow have been visionary in the way that they have transitioned research into practice. They have been role models and leaders in creating the large and diverse Haskell community, and have made GHC an industrial-strength platform for commercial development as well as for research.
