The Justice Society of America (JSA) is a superhero team appearing in American comic books published by DC Comics. The team was conceived by editor Sheldon Mayer and writer Gardner Fox during the Golden Age of Comic Books. The JSA first appeared in All Star Comics #3, making it the first team of superheroes in comic books. The original members of the Justice Society of America were Doctor Fate, Hourman, The Spectre, Sandman, Atom, Flash, Green Lantern, Hawkman, Hawkgirl, Johnny Thunder, Thunderbolt, Wildcat, Star-Spangled Kid, S.T.R.I.P.E., Doctor Mid-Nite, Starman, Mister Terrific, Black Canary, Red Tornado, Batman, Superman, Wonder Woman, Robin and Huntress. The team was originally popular, but after the popularity of superhero comics waned in the late 1940s, the JSA's adventures ceased with issue #57 of the title. During the Silver Age of Comic Books, DC Comics reinvented several Justice Society members and banded many of them together in a new team, the Justice League of America. JSA members remained absent from comics for ten years until Jay Garrick appeared alongside Barry Allen, his Silver Age counterpart, in The Flash #123. The Justice Society was established as existing on "Earth-Two" and the Justice League on "Earth-One", different versions of Earth located in different universes. This allowed for annual cross-dimensional team-ups of the teams between 1963 and 1985. New series, such as All-Star Squadron, Infinity, Inc. and a new All-Star Comics featured the JSA, their children and their heirs. These series explored the issues of aging, generational differences, and contrasts between the Golden Age and subsequent eras.
