Tom Moldvay

Thomas Steven Moldvay (Nov. 5, 1948 – March 9, 2007) was an American game designer and author, best known for his work on early materials for the fantasy role-playing game "Dungeons & Dragons" (D&D).
Career.
During the 1970s while a student at Kent State University in Ohio, Moldvay was a writer for the science fiction fanzine "Infinite Dreams".
Lawrence Schick, head of design and development of TSR, brought Moldvay on board during a time of substantial growth at TSR; at the time Moldvay was a new sort of employee at TSR, as he was a player who had enjoyed "Dungeons & Dragons" before he came to the company. With "Advanced Dungeons & Dragons" now complete, Moldvay wrote a second edition of the "Dungeons & Dragons Basic Set" (1980). As an employee of TSR, Moldvay authored or co-authored landmark D&D adventure modules such as "Castle Amber", "Isle of Dread", the rewrite of "Palace of the Silver Princess", and "Secret of the Slavers Stockade", all published in 1981. Of these, X1 – "Isle of Dread" was one of the most widely played modules of the time because it was distributed inside the D&D "Expert Set" rules.
Other Moldvay adventure modules for D&D include "The Lost City" (1982) and "Twilight Calling" (1986). In the years between 1980 and 1988, he also penned several articles in "Dragon" magazine. The fictional city of Yavdlom in the "D&D" Mystara setting – which in the following years included many locations featured in old D&D material – is an homage to him (Yavdlom being the backward reading of Moldvay). Moldvay also co-developed TSR's "Gangbusters" role-playing game and wrote adventures for TSR's "Star Frontiers" game
Moldvay developed "Lords of Creation", a role-playing game published by Avalon Hill. In 1985 he created the one-shot game "The Future King" based on Arthurian legend. In 1986 he created "The Challenges Game System", essentially a streamlining of the AD&D players handbook down to 8 pages, and the single adventure published for the system, "Seren Ironhand."
Tom Moldvay died at the age of 58 on March 9, 2007. After Moldvay's death in 2007, Steve Winter called "Isle of Dread" "Tom's work that had the widest impact", as its inclusion in the "Expert Set" "made it one of the most widely known and played adventures for years".
