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. 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 hundred-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.

Ralph Macchio began as an assistant editor on Marvel's black-and-white magazines. His career grew more colorful with writing stints on Avengers, Thor and others. As editor, he oversaw Master of Kung Fu, Moon Knight, Daredevil and more. After editing multiple Spider-Man titles, he moved to the Ultimate line, which he guided through world-shaking changes. Keith Pollard drew simultaneous runs on three of Marvel's longest-running titles- Amazing Spider-Man, Fantastic Four and Thor, including Roy Thomas and Mark Gruenwald's "Eternals Saga." During the 1990s, he singlehandedly penciled hundreds of characters for the Official Handbook of the Marvel Universe- Master Edition. John Buscema (1927-2002) literally wrote the book on being a Marvel artist - namely, How To Draw Comics the Marvel Way - and few were better qualified. His career dated back to the Timely/Atlas era of the late '40s and early '50s.

Soon after beginning the Marvel Age of Comics, Stan Lee recruited Buscema from the advertising field to the Marvel Bullpen. Buscema followed a long run on Avengers with the long-anticipated first Silver Surfer series. He subsequently succeeded Jack Kirby on Fantastic Four, Thor and other titles. By the time of his retirement in 1996, Buscema had penciled nearly every Marvel title - including his personal favorite, Conan the Barbarian.
