He lived a full life and a talented person. I was a fan of Stan's Creations back when I was growing up, but I did not know who created them before Disney got Marvel. Stan Lee's name might have been mentioned a couple times in a magazine I read, but the name did ring a bell to me at the time.
I grew up in the 1980s and 1990s. Some of Marvel's characters were so well known in the 1980s and 1990s that you don't have to be a comic book read. I was not into comic books growing up, but I played and enjoyed some Marvel video games. I even wore a Spider-Man Halloween custom when I was a kid in the 1980s.
Back in the 1980s, and 1990s X-Men, Spider-man, and Incredible Hulk were known in pop culture to those who don't follow comic books.
