After co-creating DC's Swamp Thing in 1972, Len Wein moved to Marvel for lengthy runs on some of the company's biggest titles -- Amazing Spider-Man, Fantastic Four, Incredible Hulk and Thor -- and helped bring the landmark Giant-Size X-Men #1 into the world, changing Marvel forever. Returning to DC as an editor, Wein oversaw an influx of British writing talent, highlighted by Alan Moore's historic Watchmen miniseries. Wein also has worked in television and animation, returning to his roots to develop a Swamp Thing screenplay. He has written comic-book adaptations of The Simpsons and Futurama.

As a boy, artist Dave Cockrum (1943-2006) dreamed of working in the comic-book industry; after a six-year stint in the Navy, he headed straight for the big time. With a natural talent for illustrating super heroes, Cockrum landed a gig on Legion of Super-Heroes for DC Comics. Soon after his debut, Cockrum showcased his knack for innovative costume designs, becoming the first artist to revamp the look of the classic futuristic super-hero team since its original Silver Age debut. After leaving Legion in 1975, Cockrum collaborated with writer Len Wein to create a new lineup of X-Men - including Wolverine, Nightcrawler and Colossus. Cockrum's bold new mutants quickly caught the attention of comic-book fans, transforming X-Men into a best-selling title. Although Cockrum has reduced his artistic output in recent years, his strong influence on modern creators remains steadfast - as evidenced by the release of The Uncanny Cockrum Tribute Book in 2004, boasting contributions from more than 75 notable writers and artists.
