Stan Lee, the writer, editor, and former publisher and president of Marvel Comics who co-invented Spider-Man and was responsible for turning superhero comic books into a phenomenon, died Monday at the age of 95. Lee was taken to Los Angeles’ Cedars Sinai Medical Center on Monday after suffering a medical emergency; he was declared dead shortly afterwards. To some, Lee was one of the greatest pop-culture creators of his era – the primary voice behind Marvel’s golden years and the mind that introduced characters every schoolkid knows: Not just your friendly neighborhood web-slinger but also the Fantastic Four, X-Men, Iron Man, Daredevil, the Hulk, the Avengers, and on and on.
