While Stan Lee created the concept of Spider-Man, it was Steve Ditko who created the character as well as define who he is. Although it was said that Mr. Ditko is a private man, his run on Amazing Spider-Man define his personality as he drew the characters. I think that when we read his work on Spider-Man, we're actually seeing his personal life unfold and how it shaped his personality. Tell me if I am wrong? But I feel that Peter Parker is Steve Ditko and Spider-Man was his way of escaping the world that he was never a part of.
