NetHack is the product of literally dozens of people's work. Main events in the course of the game development are described below:

• Jay Fenlason wrote the original Hack, which was modeled on the Berkeley UNIX rogue game with help from Kenny Woodland, Mike Thome and Jon Payne.
• Andries Brouwer did a major re-write, transforming Hack into a very different game, and published (at least) three versions (1.0.1, 1.0.2, and 1.0.3) for UNIX machines to the Usenet.
• Don G. Kneller ported Hack 1.0.3 to Microsoft C and MS-DOS, producing PC HACK 1.01e, added support for DEC Rainbow graphics in version 1.03g, and went on to produce at least four more versions (3.0, 3.2, 3.51, and 3.6).
• R. Black ported PC HACK 3.51 to Lattice C and the Atari 520/1040ST, producing ST Hack 1.03.
• Mike Stephenson merged these various versions back together, incorporating many of the added features, and produced NetHack 1.4. He then coordinated a cast of thousands in enhancing and debugging NetHack 1.4 and released NetHack versions 2.2 and 2.3.
• Later, Mike coordinated a major rewrite of the game, heading a team which included Ken Arromdee, Jean-Christophe Collet, Steve Creps, Eric Hendrickson, Izchak Miller, John Rupley, Mike Threepoint, and Janet Walz, to produce NetHack 3.0c.
• NetHack 3.0 was ported to the Atari by Eric R. Smith, to OS/2 by Timo Hakulinen, and to VMS by David Gentzel. The three of them and Kevin Darcy later joined the main development team to produce subsequent revisions of 3.0.
• Olaf Seibert ported NetHack 2.3 and 3.0 to the Amiga. Norm Meluch, Stephen Spackman and Pierre Martineau designed overlay code for PC NetHack 3.0. Johnny Lee ported NetHack 3.0 to the Macintosh. Along with various other Dungeoneers, they continued to enhance the PC, Macintosh, and Amiga ports through the later revisions of 3.0.
• Headed by Mike Stephenson and coordinated by Izchak Miller and Janet Walz, the development team which now included Ken Arromdee, David Cohrs, Jean-Christophe Collet, Kevin Darcy, Matt Day, Timo Hakulinen, Steve Linhart, Dean Luick, Pat Rankin, Eric Raymond, and Eric Smith undertook a radical revision of 3.0. They re-structured the game's design, and re-wrote major parts of the code. They added multiple dungeons, a new display, special individual character quests, a new endgame and many other new features, and produced NetHack 3.1.
• Ken Lorber, Gregg Wonderly and Greg Olson, with help from Richard Addison, Mike Passaretti, and Olaf Seibert, developed NetHack 3.1 for the Amiga.
• Norm Meluch and Kevin Smolkowski, with help from Carl Schelin, Stephen Spackman, Steve VanDevender, and Paul Winner, ported NetHack 3.1 to the PC.
• Jon Watte, with help from Ross Brown, Mike Engber, David Hairston, Michael Hamel, Jonathan Handler, Johnny Lee, Tim Lennan, Rob Menke, Andy Swanson, and especially from Hao-yang Wang, developed NetHack 3.1 for the Macintosh.
• Timo Hakulinen ported NetHack 3.1 to OS/2.
• Eric Smith ported NetHack 3.1 to the Atari.
• Pat Rankin, with help from Joshua Delahunty, is responsible for the VMS version of NetHack 3.1.
• Dean Luick, with help from David Cohrs, developed NetHack 3.1 for X11.
