Writer writer writer writer writer writer! Bill Finger was the writer who took Bob Kane's ridiculous original Batman proposal (which was somewhere between the Crimson Avenger and Superman) and turned it into the guy we know today. He came up with the name Bruce Wayne, created a number of the iconic gadgets and villains, and yes, had a weird thing about giant props. He also got shafted by that bastard Bob Kane and died penniless and alcoholic.
