Dave D. Taylor is a programmer who worked for id Software between 1993 and 1996 and was involved with the development of the Doom games and Quake. He created ports of both games to Irix, AIX, Solaris and Linux, and helped program the Atari Jaguar ports of Doom and Wolfenstein 3D. He describes himself as the "spackle coder" on Doom, writing unglamorous but essential things such as the status bar, sound library integration, the automap, level transitions, cheat codes, and the network chat system. The Doom II music track "The Dave D. Taylor Blues" is named for him, as is the "IDDT" cheat code.
