About the Author

Few writers/editors influenced Marvel more than Mark Gruenwald (1953-1996). Famed for pioneering work on Official Handbook of the Marvel Universe and his magnum opus Squadron Supreme, he also wrote a 100-plus-issue run of Captain America; multiple Marvel Two-in-One sagas; and several miniseries, including Contest of Champions, the first of Marvel's multi-hero sagas. He explored the Marvel Universe's ancient history in a series of What If? backup stories he also penciled.

Roy Thomas joined the Marvel Bullpen as a writer and editor under Stan Lee, scripting key runs of nearly every title of the time- Amazing Spider-Man, Avengers, Daredevil, Doctor Strange, Sub-Mariner, Thor, X-Men and more. He wrote the first 10 years of Marvel's Conan the Barbarian and Savage Sword of Conan; and launched such series as Defenders, Iron Fist, Invaders and Warlock. At DC, he developed All-Star Squadron, Infinity Inc. and related titles, proving instrumental in reviving the Golden Age Justice Society of America. Thomas later became editor of Alter Ego, a magazine devoted to comic-book history, and co-scripted the sword-and-sorcery films Fire and Ice and Conan the Destroyer.
