Bill Finger
https://en.wikipedia.org/wiki/Bill_FingerWithout whom there might not be a Batman, or at least not as we know him now. He contributed enormously to the forming of Batman, the Joker, and several decades of stories.
Living from 1917-1974, Finger died at the age of 59.
I recall reading that anytime in a Batman story you saw things like a giant typewriter, or a giant penny, those kind of visuals were a signature Bill Finger story element.
