The Unholy Trinity
The Unholy Trinity is a very early WAD for Doom that uses a large number of custom textures to create a realistic map that is based on the real life Trinity College in Cambridge. It also features an original animation sequence, and a replacement music track, which is a MIDI rendition of "Toccata and Fugue in D Minor" by Johann Sebastian Bach.
The WAD was designed by three people: Steve McCrea, Simon Wall, and Elias Papavassilopoulos, it would seem that he Unholy Trinity would be their only claim to the Doom community. Searching up their names would not come up with anything, apart from looking up Elias Papavassilopoulos, who it would seem now has a successful job working at the British multinational investment bank, Barclays, as the Managing Director (best of luck to him).
The WAD also gives credit to Peter Morgan "for the camera". Looking this name up, it came up with Peter Julian Robin Morgan, CBE, who is a British film writer, and playwright. It is very unlikely that this is the same Peter Morgan.
Another name that came up was Olivier Montanuy, he had a credit for the "wraparound sky idea". Looking up Olivier Montanuy came up with very little, however, he did have some credits on The Doom Wiki...
On the article on The Unholy Trinity;
Rial Fletcher released a Doom II conversion of Trinity in November 1996. Olivier Montanuy released a Heretic version in March 1995 (not February 1994 as the readme file claims), with the music track removed as it tended to crash the game.
An article on DeuTex;
DeuTex is an editor able to compose and decompose WAD files. It was written in 1994 by Olivier Montanuy based upon DEU and originally ran in DOS. It was later ported to Unix (including GNU/Linux, FreeBSD, and Mac OS X) and Microsoft Windows (with a graphical front-end for Windows 3.1, WinTex). André Majorel maintained DeuTex up until 2005. It is currently maintained by several contributors on GitHub.
His name also comes up on an Aliens TC article;
Aliens TC (original version, part 2 bug fix for Doom v1.2 users) at Doomworld/idgames. These three files are Olivier Montanuy's package, which includes some batch files to simplify installation and prevent permanent alteration of the user's IWAD[.]
Olivier's name would also come up on the Official Doom FAQ, on line 5664, 5747, and 6389;
