Bob Kane created Batman and hired the at-the-time 17 year old Jerry Robinson to ink the comics. Although it’s not without some controversy, it is now widely accepted that Jerry Robinson created the Joker character.
Robinson was born in New Jersey, January the 1st, 1922 and died in his sleep on the 8th of December 2011. He was nearly 90.
Inducted into the Comic Book Hall of Fame in 2004, Jerry Robinson had gone on to fight for creator’s rights – such as helping to ensure that Jerry Siegel and Joe Shuster got both recongition and compensation they hadn’t previously had for creating Superman.
Jerry Robinson’s influence on Batman goes beyond the Joker. He suggested the name “Robin”, based on Robin Hood, to Kane and Bill Finger while the pair planned to add a sidekick to the Batman series.
