Lennart Augustsson is a Swedish computer scientist. He was formerly a lecturer at the Computing Science Department at Chalmers University of Technology. His research field is functional programming and implementations of functional programming languages.[1]

Augustsson has worked for Carlstedt Research and Technology, Sandburst, Credit Suisse, Standard Chartered Bank, Facebook, X Development, Google and is currently employed by Epic Games.[2]



Augustsson was intimately involved in early development of the multi-user dungeon (MUD) LPMud, both in the LPMUD driver and the CD mudlib. His MUD community pseudonym is Marvin.

He authored several hardware device drivers for the Berkeley Software Distribution (BSD) Unix operating system NetBSD.[3]



Augustsson has developed several programming languages and implementations, including:

Augustsson has written three winning entries in the language C for the International Obfuscated C Code Contest:
