In the original version of Wonder Woman's origin story, Steve Trevor was an intelligence officer in the United States Army during World War II whose plane crashed on Paradise Island, the isolated homeland of the Amazons. He was nursed back to health by the Amazon princess Diana, who fell in love with him and followed him when he returned to the outside world. There she became Wonder Woman (and also his coworker, Diana Prince).
Steve Trevor was portrayed as an American military hero who often fought battles both alone and alongside Wonder Woman. At the same time, he was also a traditional superhero's love interest, an esquire-in-jeopardy: repeatedly becoming kidnapped and needing to be rescued by Wonder Woman, as well as pining after the superheroine in the red-and-blue outfit while failing to notice her resemblance to his meek, bespectacled co-worker Diana Prince.
After Marston's death, much of the original supporting cast had less attention paid to them. Under writer-editor Robert Kanigher, both his and Diana's personalities were compromised considerably, with Steve beginning to seem threatened by his heroine's power, and with Diana almost beginning to seem apologetic about it. As with Superman stories of the same period, the question of marriage was never far from the couple's minds. There was also considerable attention given to the threat of the Amazon's secret identity being revealed.
In 1968, Diana chose to give up her powers and cut ties with her native Paradise Island to stay close to Steve. Trevor was killed off in the next issue. He was thus absent for the next few years of the comic. In the mid-1970s, following the return of the heroine's powers, Trevor was brought back to life by Aphrodite, and given a new identity as the brunette Steve Howard. In 1978, he was killed off again. He would be replaced in 1980 by a double from another, undisclosed dimension of the Multiverse. For the next few years the classic relationship of Wonder Woman and Steve Trevor would be essentially restored, and explored with some detail. In 1985 with issue # 322, writer Dan Mishkin dealt with Trevor's three separate "lives," and after much explanation merged the "new" Steve with the old.
During this same period in early 1980s issues of Wonder Woman, the villainous Doctor Psycho fused Steve's image with Wonder Woman's abilities and became "Captain Wonder," sporting a costume similar to Wonder Woman's. In the final issue of the original Wonder Woman series, Steve and Diana married.
Post-Crisis and Beyond
At the end of the series, the Wonder Woman and retired four-star General Steve Trevor of pre-Crisis Earth-Two traveled to Mount Olympus to live with the Greek gods and goddesses, as many of the other pre-Crisis Earth-Two heroes died or merged into a new streamlined continuity. The Wonder Woman of pre-Crisis Earth-One was devolved back into the mystical clay from which she was formed (technically dying), thus allowing Wonder Woman and her supporting characters to be re-introduced with new origins, backgrounds and plotlines.
With the restart of the series in the third volume after the Crisis on Infinite Earths series, Steve Trevor was revamped to be considerably older than Diana. In addition, the two of them never had a romantic relationship. Years before Trevor's crash landing on Themyscira (the modern name for Paradise Island), his lost mother Diana Rockwell Trevor had also crashed there, finding the Amazons battling a large monster. Seeing they were close to defeat, Diana Trevor used her pistol on the beast, giving the Amazons an advantage in the battle. Trevor dies as a result. After her death the Amazons considered the outworlder to be an honored hero for her sacrifice. It is from her that Queen Hippolyta named her daughter Diana and also from her that the Amazons came into possession of a gun originating from Man's World. It's this familial link that led to the god Ares to manipulate Steve into bombing Themyscira to eliminate the Amazons. However while in flight and guided to the island, Trevor realized he was about to needlessly bomb civilians and attempted to abort the mission. Steve's co-pilot, a minion of the war-god, transforms into a monster in an attempt to continue the attack. Diana rescues Steve from the resulting disaster.
Bringing the unconscious Trevor to the island, Diana recognized his American flag insignia on his uniform mirrored her own armor's color motif and took this as a sign of where she had to go to begin her fight against Ares. Thus inspired, Diana took Trevor to 'Man's World' in the city of Boston and began her calling. Since then, Trevor and Diana have been close friends despite him being old enough to be her father. This version of Steve Trevor went on to marry Etta Candy and became the Deputy Secretary of Defense for the U.S. government.
Following the recent Infinite Crisis limited series, Wonder Woman's origin has yet again been revamped, as by extent her supporting cast. Diana is no longer a recent arrival to man's world, but instead has been around for a considerable time, having been involved in the creation of the Justice League of America (as was the case in the group's Silver Age introductory story in 1960). Although Steve still remains close friends with Diana and married to Etta, his history with Diana has not fully been developed.
The New 52
In the aftermath of the Flashpoint storyline, history is rewritten. In a conversation between Steve Trevor and Amanda Waller five years ago, Steve tries to convince Waller that Diana and the Amazons are not a threat to global security, as they are benevolent. Steve then becomes the U.S. government's liaison to Diana during her stay in Washington, D.C. and later becomes the head of the newly formed A.R.G.U.S., (Advanced Research Group for Uniting Super-Humans), as well as the UN's liaison to the newly formed Justice League. Promoted to the rank of Colonel, his assistant is Etta Candy and he has made his feelings and attraction to Wonder Woman clear to her, although his feelings haven't been reciprocated. The hero Black Orchid is revealed to be A.R.G.U.S. Agent Alba Garcia, working covertly for Justice League Dark to monitor John Constantine. 
Steve will also be a member of several team books, including Team 7, launching in September 2012, and Justice League of America, launching in 2013.
A similar character named Howard Shelton appears in the Squadron Supreme series as the aged husband of Power Princess (taking the post-Crisis age difference even further). Though they met decades earlier, only he aged and Power Princess took care of him even as an old man. He was later quietly killed by a counterpart of Hyperion who almost immediately took up a relationship with Power Princess.
In the Elseworlds Wonder Woman: Amazonia, Stephen Trevor is a Royal Marine who tricked the Amazon's into being loyal, but he called down the British Empire and slaughtered them all, except Diana. He brings her to Man's World to put her into stage plays re-enacting Biblical stories. Diana later kills Stephen as revenge. 
The parody superhero team The Inferior Five (first published by DC in 1966) included Dumb Bunny, a strong but unintelligent woman described as the daughter of "Princess Power" and "Steve Tremor", pastiches of Wonder Woman and Steve Trevor.
In the alternate timeline of the "Flashpoint" event, Steve and Wonder Woman have no relationship instead it appears that he is in love with Lois Lane. Steve made an appearance in London where he is waiting at a rendezvous point for Lois Lane as he is attacked by Wonder Woman and the Amazons. Wonder Woman catches him by the neck with her Lasso of Truth and begins interrogating him after he is temporarily able to resist the lasso's effects. He explains that he was hired to extract Lois Lane from New Themyscira because she was sent to gather information on the Amazons for Cyborg who's amassing superhumans to stop the fighting between Wonder Woman and Aquaman. Steve's fate remains unrevealed, as a subject of Wonder Woman asked her what to do with him. Update: He dies strangled by WonderWoman.
