“With a heavy heart, we share our deepest condolences with his daughter and brother, and we honor and remember the creator, voice and champion of Marvel,” reads a statement from Marvel. The company also posted this Lee quote on its remembrance page, which recounts his lifetime of work:

“I used to be embarrassed because I was just a comic-book writer while other people were building bridges or going on to medical careers. And then I began to realise: Entertainment is one of the most important things in people’s lives. Without it, they might go off the deep end. I feel that if you’re able to entertain, you’re doing a good thing.”
