Jewish comic writer, Stan Lee, or his birth name, Stanley Lieber, along with artist, jack Kirby (real name Jacob Kurtzberg), created many of Marvel’s major heroes and villains, in the 1960s “silver age’ of comics. There have been disputes over the years about who did what, with Kirby and Steve Ditko being bitter about Lee’s treatment of them. Both left Marvel; Kirby came back briefly then left again. Talk about job satisfaction. And, there were the law suits.

Recently Lee’s world seemed to have been falling apart with a sexual assault lawsuit and other hassles of being rich. So, it was probably a good time to leave this veil of tears for warmer climates, maybe visiting super-friends from other dimensions.
