74 – Lennart Augustsson
This episode is a deep dive into the evolution of Haskell and functional programming with one of its pioneers, Lennart Augustson. It reflects on decades of work in language design and compiler implementation. Lennart speaks about his early involvement in the creation of Haskell, shares thoughts on type systems, performance, and the balance between purity and practicality. The conversation ranges from personal history to big-picture views on the evolution of programming languages, with plenty of insight into what makes Haskell both powerful and challenging. A rare opportunity to hear from one of the foundational voices in the functional programming world.
This is a joint podcast episode with the Type Theory Forall podcast that was recorded in front of a live audience at ZuriHac 2025.

We drive change.
Watch Simon Peyton Jones announce the Haskell Foundation at the Haskell eXchange conference on November 4, 2020.
In this keynote, Simon talks about the Haskell Foundation's launch and its goals. At the end, he is joined by a panel of HF volunteers to take questions from the audience.
Not “just another programming language”
Haskell embodies a radical and elegant attack on the entire enterprise of writing software. It profoundly influences the world of software for the better.
Our Ethos
Ideas that guide our every decision
Faithfulness to Haskell’s founding design principles.
Haskell’s design puts principle ahead of expediency by cleaving closely to the principles of purely functional programming.
Open source.
All Haskell Foundation efforts are open source.
Empowering the community.
HF augments, celebrates, and coordinates the contributions and leadership of Haskell’s vibrant community.
Openness, friendliness, and diversity.
For many, Haskell is more a way of life than a programming language. All are welcome, all can contribute. To this end we have adopted the Haskell Guidelines For Respectful Communication.
Transparency.
All technical decisions related to HF’s open source projects are proposed and debated in public.
Haskell Foundation Discourse
The Haskell Foundation category in the Haskell Discourse is where we make official announcements, and have discussions with the community.
Haskell Foundation Board Google Group
Official communication channel for HF Board members, the archive is publicly available.
