Famous comic book creator Stan Lee, who created over 300 characters while working as a writer and then editor-in-chief at Marvel.

American comic book writer, editor, publisher, and producer Stan Lee was born on December 28, 1922. He rose through the ranks of a family business known as Timely Comics, which later evolved into Marvel Comics. For two decades, Lee served as Marvel's chief creative officer, overseeing its transformation from a general publishing division into a multimedia corporation that significantly influenced both the comics and film industries. 

In collaboration with various Marvel colleagues, particularly co-plotters and artists Jack Kirby and Steve Ditko, he co-created numerous iconic characters, including Spider-Man, the X-Men, Iron Man, Thor, the Hulk, Ant-Man, the Wasp, the Fantastic Four, Black Panther, Daredevil, Doctor Strange, the Scarlet Witch, and Black Widow. These roles marked a shift towards a more naturalistic approach to superhero comics in the 1960s. In the 1970s, Lee fought against the restrictions set by the Comics Code Authority, which indirectly contributed to changes in its policies. In the 1980s, he attempted to promote Marvel properties through various means, with mixed results. 

After retiring from Marvel in the 1990s, Lee remained a prominent figure associated with the company. He frequently appeared in cameo roles in films and television shows based on Marvel properties and received executive producer credits, making him the highest-grossing film actor of all time. He continued to be involved in independent creative projects until his death in 2018 at the age of 95. Lee was inducted into the Will Eisner Award Hall of Fame in 1994 and the Jack Kirby Hall of Fame in 1995. In 2008, he received the National Medal of Arts from the National Endowment for the Arts.

Lee died on November 12, 2018 at Cedars-Sinai Medical Center in Los Angeles. He was rushed there for emergency treatment earlier in the day. Lee had previously been hospitalized for pneumonia in February of that year. His death certificate listed the immediate cause of death as heart disease, respiratory failure and congestive heart failure. It also indicated that he was suffering from aspiration pneumonia. His body was cremated and his ashes were given to his daughter. 

Roy Thomas, who succeeded Lee as Marvel's editor-in-chief two days before his death, said, "I think he was ready to go. But he was still talking about doing more cameos. As long as he had the energy for it and didn't have to travel, Stan was always ready to do more cameos. He got more pleasure out of those than anything else." Lee's last words to Thomas were "God bless you. Take care of Roy, my son", leading fans to speculate that he was referring to Spider-Man. However, Lee had long nicknamed Thomas Roy "The Boy" Thomas, as Lee sometimes introduced himself as Stan "The Man" Lee.

In the end, we can only say one thing about him: thank you for giving us heroes, hope, and a universe that changed lives forever.
