Detective Comics #27
Detective Comics #27 holds an irreplaceable place in comics history as the first published appearance of Batman — introduced here as 'The Bat-Man' — alongside his enduring ally Commissioner Gordon, making it the fountainhead of what would become DC's flagship character and the title series from which the publisher drew its very name. The six-page lead story, 'The Case of the Chemical Syndicate,' established the foundational template of a wealthy, masked detective-vigilante operating outside the law, a template that shaped superhero storytelling for decades. The issue also captures a pivotal transitional moment in the medium: Detective Comics had been a thriving anthology of pulp-inspired crime and adventure strips — starring characters like Slam Bradley, Speed Saunders, and the Crimson Avenger — and Batman's arrival would gradually transform it from an ensemble crime book into a superhero vehicle, permanently altering the direction of the genre. The story's debut was so culturally durable that DC and other creators have retold and reimagined 'The Case of the Chemical Syndicate' across multiple decades, treating the issue as a touchstone of the medium's own origin mythology.
Detective Comics #27 (1939) introduces the world to the Bat-Man in "The Case of the Chemical Syndicate," a gripping mystery where the enigmatic vigilante takes on a deadly corporate conspiracy. Written by Bill Finger and illustrated by Bob Kane, this landmark issue marks the first appearance of Batman, with Kane also handling the cover art.

In early 1939, following the runaway commercial success of Superman in Action Comics #1, editor Vin Sullivan tasked freelancers to deliver new superhero concepts; Bob Kane responded quickly, conceiving the initial visual idea for 'The Bat-Man,' while his studio collaborator Bill Finger — then working as an uncredited ghost writer — rewrote the script, devised the character's civilian name Bruce Wayne, and redesigned the costume from a caped red-and-black figure into the gray-and-black cowled silhouette that would define the character. Kane brought the concept to Sullivan and negotiated a contract solely in his own name, locking Finger out of any official credit; Kane remained Batman's sole credited creator for over seven decades until DC formally recognized Finger as co-creator in 2015. The debut story's plot is widely recognized by historians as closely paralleling — some say plagiarizing — Theodore Tinsley's 1936 Shadow novel 'Partners of Peril,' which shares nearly the same chemical-company murder scheme.
