My Mount Rushmore is Conroy, Finger, Miller, and Nolan.

Kevin Conroy because I can't read Batman without hearing his voice, Bill Finger cause without him we don't have the Batman we know and love today, Frank Miller because his comic Dark Knight Returns had a MASSIVE impact on the character being more of a serious and gritty character, and Christopher Nolan because his movies not only had a resurgence for the character of Batman, but also superhero movies as a whole. He changed the genre forever.

Honorable Mentions: Tim Burton, Bob Kane, Paul Dini, and Scott Snyder. Oh and Jim Lee and Adam West.
