On March 6 1940 WWII had not yet gone global, a lot of countries had not been affected by the war. Although the anxiety of an impending war was prevalent it was still a matter of “business as usual” in a majority of nations.
On that same day Detective Comics introduced Batman’s sidekick. Dick Grayson aka Robin-the Boy Wonder. About a year after Batman’s debut, Batman creators Bob Kane and Bill Finger introduced Robin the Boy Wonder in Detective Comics #38 (1940). The name “Robin the Boy Wonder” and the medieval look of the original costume were inspired by The Adventures of Robin Hood.
Although Robin was introduced on March 6 1940, the comic was only published in April 1940.
