Andries Evert Brouwer (born 1951) is a Dutch mathematician and computer programmer, Professor Emeritus atEindhoven University of Technology (TU/e). He is known as the creator of the greatly expanded 1984 to 1985 versions of theroguelike computer gameHack that formed the basis forNetHack.^[1] He is also aLinux kernelhacker. He is sometimes referred to by the handleaeb.

Born in Amsterdam, Brouwer attended thegymnasium, and obtained his MSc in mathematics at the University of Amsterdam in 1971. In 1976 he received his Ph.D. in mathematics fromVrije Universiteit with a thesis entitled "Treelike Spaces and Related Topological Spaces", under the supervision of Maarten Maurice and Pieter Baayen, both of whom were in turn students ofJohannes de Groot.^[2] In 2004 he received an honorary doctorate fromAalborg University.

After graduation Brouwer started his academic career at the Mathematisch Centrum, laterCentrum Wiskunde & Informatica. From 1986 to 2012 he was Professor atEindhoven University of Technology (TU/e).

Brouwer's varied research interests include several branches ofdiscrete mathematics, particularlygraph theory,finite geometry andcoding theory.

He has published dozens of papers in graph theory and other areas ofcombinatorics, many of them in collaboration with other researchers. His co-authors include at least 9 of the co-authors ofPaul Erdős, giving him anErdős number of 2.^[3]

In December 1984, while at theCentrum Wiskunde & Informatica (CWI), he made the first public release ofHack onUsenet.Hack was an implementation ofRogue originally written in 1982 byJay Fenlason and a few others, but Brouwer heavily modified and expanded it. He distributed a total of four versions ofHack between December 1984 and July 1985.

Thesource code was released asfree software, and it was widely copied, played, andported to multiple computer platforms. When Mike Stephenson brought together a large development team via Usenet to produce an enhanced version in 1987 incorporating changes from many of theHack derivatives, they respected Brouwer's wishes by renaming their gameNetHack, as Brouwer might "...eventually release a new version of his own."^[4]

Brouwer has also been involved with the development ofUnix-like computeroperating systems based on the Linux kernel. He was previously themaintainer of theman pager programman^[5] and the maintainer of the Linux man-pages project (from 1995 to 2004),^[6] and he is a kernel maintainer in the areas of disk geometry andpartition handling.^[7]

Brouwer also serves as specialist in security aspects of Unix and Linux for EiPSI (Eindhoven Institute for the Protection of Systems and Information), TU/e'sinformation security research institute.^[8]
