Happy 110th Birthday to Bill Finger, the co-creator of Batman. He was truly an unsung hero who helped shape the Bat universe as we all know it today. Unfortunately, due to some shady work by co-creator Bob Kane, his contribution was widely forgotten for 76 years until, in 2015, DC Comics officially recognized Finger's work thanks to his biographer Marc Nobleman and granddaughter Athena Finger. Now everyone's happy (except for that one jerk on YouTube, who was clearly a Bob Kane fanatic, refused to accept it and started giving me "evidence" to prove that I was wrong, even though his "facts" were extremely outdated and had been refuted years ago. It took fans on YouTube and Reddit to shut him up).
Do check out the Batman & Bill documentary on Hulu to learn more. In the meantime, Happy Birthday, Bill!
