Short answers, pulled from the story.
Stan Lee was an American comic book writer, editor, publisher, and producer who served as Marvel's primary creative leader for two decades. In collaboration with artists including Jack Kirby and Steve Ditko, he co-created Spider-Man, the X-Men, Iron Man, Thor, the Hulk, the Fantastic Four, Black Panther, Daredevil, Doctor Strange, and Black Widow.
Stan Lee was born Stanley Martin Lieber on the 28th of December 1922 in Manhattan. He died on the 12th of November 2018 at Cedars-Sinai Medical Center in Los Angeles, aged 95.
Stanley Lieber adopted the pen name Stan Lee because the low social status of comic books embarrassed him. He wanted to save his real name for the Great American Novel he planned to write one day, and years later he adopted Stan Lee as his legal name.
The Marvel Method was Stan Lee's workflow for producing comics under heavy deadlines. He would brainstorm a story with an artist and provide a brief synopsis, the artist would draw the pages and decide the panel-to-panel storytelling, and Lee would then add word balloons and captions, making the artists effectively co-plotters.
Stan Lee challenged the Comics Code Authority in 1971 by publishing a three-issue Amazing Spider-Man drug-addiction story, issues #96 through #98, without the Code's seal after it was refused. The issues sold well, and the Code later loosened to permit negative depictions of drugs.
After his wife Joan Boocock died on the 6th of July 2017, Stan Lee faced lawsuits and accusations of elder abuse. His business manager Keya Morgan was placed under a restraining order in August 2018 and later charged with five counts including false imprisonment, fraud, and elder abuse, and Lee sued former manager Jerardo Olivarez over alleged changes to his will and transfers from his accounts.
