of Jay Garrick in the 2014 The Flash series. The various incarnations of the Flash also feature in animated series such as Superman: The Animated Series, Justice League, Batman: The Brave and the Bold and Young Justice, as well as the DC Universe Animated Original Movies series. Publication history Golden Age The Flash first appeared in the Golden Age Flash Comics #1 (January 1940), from All-American Publications, one of three companies that would eventually merge to form DC Comics. Created by writer Gardner Fox and artist Harry Lampert, this Flash was Jay Garrick, a college student who gained his speed through the inhalation of hard water vapors.

After several more appearances in Showcase, Allen's character was given his own title, The Flash, the first issue of which was #105 (resuming where Flash Comics had left off). Barry Allen and the new Flash were created by writers Robert Kanigher and John Broome and cartoonist Carmine Infantino. The Silver Age Flash proved popular enough that several other Golden Age heroes were revived in new incarnations (see: Green Lantern). A new superhero team, the Justice League of America, was also created, with the
