BATMAN TIMELINE – Batman in 1940

Robin Begins

7749

1940 was an important year for Batman as Robin, The Joker, Hugo Strange, and Catwoman all made their first appearances in the pages of Batman comics. 1940 also saw Batman adopt a “no killing” rule as well as an aversion to firearms.

FEBRUARY: Batman takes on the evil Dr. Hugo Strange for the first time in DETECTIVE COMICS #36. Coming before The Joker or any other of Batman’s most famous rogues, Dr. Hugo Strange was The Dark Knight’s first re-occuring supervillain.

APRIL: Richard “Dick” Grayson’s origin as Robin, The Boy Wonder is detailed in DETECTIVE COMICS #38. Taken in by Bruce Wayne after his circus-performing parents are murdered by mobster Boss Tony Zucco, Dick Grayson is trained by The Batman and soon joins his war on crime as Robin.

SPRING: With BATMAN #1, Batman gets his own comic book. In it, both The Joker and Catwoman (called “The Cat” originally) make their debut in “The Joker”/”The Joker Returns” and “The Cat” respectively. Dr. Hugo Strange returns in the story “The Giants of Hugo Strange.” Read BOF’s review of BATMAN #1 (Vol. 1) HERE.


JUNE: The Basil Karlo version of Clayface makes his first appearance in the story “The Murders of Clayface” in DETECTIVE COMICS #40.

FALL: “The Cat” becomes “The Cat-Woman” and gets her first costume – a cat-head mask, red cape, and an orange dress – in BATMAN #3.

Bill "Jett" Ramey
Bill “Jett” Ramey isn’t just a Batman fan — he’s one of the founding fathers of the online Batman community. As the creator and Editor-in-Chief of Batman-On-Film.com, the original and longest-running Batman news and commentary site, Jett helped carve the very bedrock of modern fan internet press. If there is a Mount Rushmore of this stuff, his face is already up there — sunglasses on, arms crossed, probably telling someone to calm down. A lifelong Dark Knight disciple, Jett has spent decades championing filmmaker‑driven Batman stories, cutting through fanboy noise with a Texas‑sized dose of honesty, and keeping the conversation smart, civil, and drama‑free. He’s the BOF Godfather — the guy who was here before the hashtags, before the clickbait, before the algorithms… and he’s still here, still talking Batman, still calling it straight. When he steps out of Gotham, Jett is pure Texas. He bleeds Dallas Cowboys blue, blasts Elvis and rock ’n’ roll, and has a deep appreciation for cold beer, dive bars, and Texas Longhorns football. He works out, he cooks, and he can grill like a man who’s earned the right to say “don’t assume” when he tells you he lives in the great state of Texas. He shares that home with his wife — “Announcer Rachel” — and their dogs: Gracelin the Labradoodle and Presley, a rescue pup named after the King himself.
