For other comic book characters with the same name, see The Sandman (comics).

The Sandman is a comic book superhero in the DC Comics universe, best known for his "costume" consisting of a green business suit and gas mask, and for operating in the 1940s. He is a member of the Justice Society of America. He was created by writer Gardner Fox and artist Bert Christman and first appeared in World's Fair Comics #1 (1939).

Following his debut, the Sandman appeared in Adventure Comics from issues #40 to #102. Wesley Dodds (his real name) was one of the earliest superheroes (then called "mystery men" for lack of a better term), though his status as such is debatable as he came rather from the detective tradition seen in the pulps of the 1930s. He had no superhuman powers, but was armed with an exotic "gas gun" that could compel villains to tell the truth, as well as put them to sleep.

In 1941, he was given a more superheroic yellow and purple costume by artist Chad Grothkopf , as well as a yellow-clad kid sidekick, Sandy the Golden Boy. It was this version of the character which was famously written and drawn by Joe Simon and Jack Kirby.

During and after the Silver Age the Sandman made occasional appearances in JSA/JLA teamups. He was one of a number of JSA members who found themselves in the "Ragnarok Dimension" during the early Modern Age. A minor retcon in Neil Gaiman's Sandman suggested that his chosen identity was a result of Dream's absence from his realm, and that he has an aspect of the Dreaming within him.

An updated version of the original Sandman appeared in a 1993 series intended for adult readers entitled Sandman Mystery Theatre.

A one-off special by Gaiman, Sandman Midnight Theatre, has the Sandman interact with the back-story of Gaiman's book, as a visit to Britain leads to an encounter with Roderick Burgess and the imprisoned Dream.

In the present day setting, the JSA were released from Limbo, and a retired Wesley Dodds was shown as the "elder statesman" of superheroes, most notably in a team-up with Jack Knight, the son of his JSA teammate Starman.

In 1999, a year after the end of the Sandman Mystery Theatre series, Wesley died in JSA #1. His still-youthful but now grown-up sidekick, Sandy the Golden Boy, became known simply as Sand and took his mentor's place as a member of the Justice Society of America. Like the Marvel Comics Sandman, Sand had gained the power to turn into sand, though otherwise he was the true heir to the original, pulp fiction-inspired Sandman in all but name.
