Jerry Robinson, the man that created The Joker, Two-Face, and Robin, has passed away at the age of 89, according to Comic Book Resources. Robinson began his career at 17 working as an inker for artist Bob Kane on Batman. Soon, he began to flex his creative muscle by adding his own art to the book. This led to the creation of some of the most memorable characters in Batman's 70+ year history.

Even though Robinson had feuded with Kane over who got the credit for these characters, it has been widely accepted that they are the brainchild of Robinson. Over the years, Robinson still worked on comics, but he also became an advocate for creator's rights and a historian of the medium.

Recently he was hired by Warner Brothers and Christopher Nolan as a creative consultant on The Dark Knight, which, of course, featured the Joker as the main villain. Not only did this Joker physically resemble Robinson's, but the storyline also heavily borrowed plot-points from his original comics. It's a testament to how timeless Robinson's work has become. 

Any comic book fan unfamiliar with Robinson's original work should definitely grab some Batman reprints from the '40s to truly understand what an impact he had on the entire industry.
