Stan Lee, the legendary writer, editor, and publisher of Marvel Comics whose creations made him a comic book icon has died. He was 95.  Lee was reportedly rushed to Cedars-Sinai Medical Center in Los Angeles where he later died, a family representative told The Hollywood Reporter. The cause of death has not been immediately released.

Lee, who began in the business in 1939 at age 18 at Timely Comics and created or co-created Black Panther, Spider-Man, the X-Men, the Mighty Thor, Iron Man, the Fantastic Four, the Incredible Hulk, Daredevil and Ant-Man, among countless other characters, boosted his career in 1961 when Lee and artist Jack Kirby co-created the Fantastic Four and saw it go on to become a hit, prompting the company to change its name to Marvel Comics.

Lee rapidly was promoted at Marvel, holding positions as writer, editor, film executive producer, editor-in-chief, publisher, and chairman. Since moving on from Marvel, he has remained in the public eye largely thanks to the success of Marvel’s movies where he is listed as executive producer and can be spotted in cameos.

Lee is survived by his daughter and younger brother Larry Lieber, a writer and artist for Marvel. Another daughter, Jan, died in infancy. His wife, Joan, was a hat model whom he married in 1947.
