This new Flash was Barry Allen, a police scientist who gained super-speed when splashed by chemicals after a shelf of them was struck by lightning. He adopted the name The Flash after reading a comic book featuring the Golden Age Flash. 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).
The Silver Age Flash proved popular enough that several other Golden Age heroes were revived in new incarnations. A new superhero team, the Justice League of America, was also created, with the Flash as a charter member.
This second incarnation of the Flash is generally considered the first hero of the Silver Age of comic books and the superhero has remained one of DC‘s most popular ever since. Each version of the Flash has been a key member of either the Justice Society of America or the Justice League, DC’s all-star teams. Wally West has recently rejoined the Justice League.
