I always thought it was by John Carmack. Even says so on the title screen:
Carmack really liked putting his name on the games he worked on, e.g. the main source code file of Wolf3D starts with
/* ============================================================================= WOLFENSTEIN 3-D An Id Software production by John Carmack ============================================================================= */
In the case of Softdisk games however AFAIK it was just that the games were largely credited to the individuals who designed and programmed them (same person at the time) and the art, etc, was done by artists at Softdisk (specifically Andrian Carmack) who were doing other non-game related stuff too (softdisk had a lot of software unrelated to games). The wikipedia credits id most likely because almost everyone who worked on games at Softdisk moved on to create id Software.
