I agree that some of the details of Stan and Jack's history together are a bit unsavory. But I do believe that Stan really propelled the company into the mainstream with his tireless promotion. Call it what you will, but seeing this through my eyes as a kid...ignorance was really bliss. I thought that Stan was indeed the man! I devoured the books and wanted to know who wrote, penciled, and colored each of them. I was a fan. My visions of the bullpen were of a group of folks having the times of their lives.
Jack was no doubt a major driving force behind a lot of the creations and deserved a much better fate, but I don't discount what Stan was doing at all.
