Creator: Len Wein

Writer and Editor who made a massive impact on both of the big two.  

Here’s just some of the great things he did: Both created Swamp Thing and wrote one of the earliest Man-Thing scripts, creating the characters power to burn people who feared him; wrote Rutland Parade DC/Marvel crossovers; created Human Target, later turned into a TV show; and created a little-known dude named Wolverine, who he then included when he rebooted The X-Men (also creating characters like Storm, Nightcrawler, and Colossus), which then went on to be the most successful title in comic book history.
