Andries Evert Brouwer (born 1951) is a Dutch mathematician and computer programmer, Professor Emeritus at Eindhoven University of Technology (TU/e).
He is known as the creator of the greatly expanded 1984 to 1985 versions of the roguelike computer game Hack that formed the basis for NetHack.
Hack was an implementation of Rogue originally written in 1982 by Jay Fenlason and a few others, but Brouwer heavily modified and expanded it.
The source code was released as free software, and it was widely copied, played, and ported to multiple computer platforms.
"[4] Brouwer has also been involved with the development of Unix-like computer operating systems based on the Linux kernel.
