Timothy James Kask (born January 14, 1949) is an American editor and writer in the role-playing game industry. Kask became interested in board games in his childhood, and later turned to miniatures wargames. While attending university after a stint in the US Navy, he was part of a group that playtested an early version of the new role-playing game Dungeons & Dragons (D&D) for game co-designer Gary Gygax. Gygax hired him as the first employee of TSR, Inc. in 1975.
