Mark Gruenwald

Mark Gruenwald (1953-1996) was an American comics writer and editor best known for his work at Marvel Comics. Aside from numerous other achievements (including some absolutely wonderful runs on Captain America, Quaar and Squadron Supreme) he was also responsible for the creation of the generally pretty amazing Official Handbook of the Marvel Universe series. Unfortunately, he got a lot of stuff in the entries for the Black Knight and Captain Britain in the Deluxe Edition completely wrong. But, hey, he tried!
