Today marks the 77th anniversary of the DC Comics publication Batman (Vol 1) 1 from April 25 1940. The 1st story, originally untitled, is the first appearance of the character The Joker, written by Bill Finger and illustrated by Bob Kane and Jerry Robinson. In the dark of night, The Joker corrupts radios all over the city. He states that at midnight he will kill Henry Claridge and steal the Claridge Diamond. Even with dozens of policemen protecting the millionaire in his home, at the stroke of midnight Claridge dies with a grotesque grin on his face. As the policemen check the safe, the diamond is switched with a replica, with a Joker playing card left as ‘The Sign of The Joker!” Elsewhere, Joker rejoices how he fooled the police, placing a solution into Claridge 24 hours prior while he was sleep, stealing the diamond the night before his announcement. The next morning, Bruce Wayne and Dick Grayson read of Claridge’s death by The Joker in the paper. That same night, over the radio, the Joker announces in one hour Jay Wilde will die and he will have the Ronkers Ruby. Policemen go to Wilde’s home, but all is lost when Wilde has Joker’s venom in his veins and a strange gas is released out of the armor in the lounge. As the Joker emerges in triumph, he has successfully paralyzed the policemen long enough to steal the Ruby and escape. The criminal underground get word of the Joker and boss Brute Nelson tells them to spread the word that he will take out The Joker. Bruce Wayne hears of this and transforms into the Batman on his way to Nelson’s when the Joker arrives. Batman beats up Nelson and his men, but Joker has the last laugh shooting Nelson down. After Judge Drake is killed by Joker, After leaving the Judge’s home, Robin follows and is attacked and tied up by the Joker. Using his detective skills the Batman finds Robin and does hand to hand combat with this grinning ghoul. Joker escapes once more but a freed Robin tells Batman he is off to steal the Cleopatra Necklace. Their last battle ensues, and a kick to the face by Robin has the Joker flying off the building, caught by Batman, knocked out and arrested. The issue ends with Joker behind bars.
