The Atom (Raymond "Ray" Palmer) is a superhero appearing in American comic books published by DC Comics. The character was created by editor and co-plotter Julius Schwartz, writer Gardner Fox and penciler Gil Kane.

He was played by Brandon Routh in Legends of Tomorrow in the shared DC Arrowverse on The CW. His character first appeared in the third season of Arrow. Publication history The Atom debuted in Showcase #34 (cover-dated Oct. 1961) from the DC Comics precursor, National Comics. Early comics-fandom pioneer Jerry Bails wrote to the National Comics editor Julius Schwartz in December 1960 outlining an updated version of Al Pratt, the company's 1940s Golden Age Atom. Bails and future Marvel Comics editor-in-chief Roy Thomas collaborated on a suggested version that incorporated elements of a Golden Age hero, Quality Comics' Doll Man. Eventual Atom writer Gardner Fox wrote Bails on January 1, 1961, stating that Schwartz passed along Bails' letter to him.

Kane, unaware of Bails' suggestions, said he did "a series of drawings" on large illustration boards, including a depiction of the new Atom riding a German shepherd dog and another of a pistol firing at the Atom, who wore the costume he eventually would in his comic debut but without a belt. Kane, who lived in Jericho, New York, on Long Island, at the time, drove to the nearby Hicksville home of DC production person Tom Nicolosi, who colored the drawings using St. Martin's dyes. Schwartz, after seeing the drawings, had the belt added, a detail Kane said he disliked since "it broke up the costume lines."

He added that he and Fox together plotted the early stories of this new Silver Age Atom. Fox said in 1979, "I doubt that any feedback from Bails
