James Bartholomew "Jimmy" OIsen was born and raised in Metropolis. He was mostly raised by his mother after his father, a military man who was later revealed to be working for Cadmus, disappeared during a mission. Jimmy eventually obtained employment at the Daily Planet, where he worked as a photographer and reporter. He soon established a close relationship with his coworkers Perry White, Clark Kent and Lois Lane, as well as developing a friendship with Superman.
Jimmy Olsen was created by Jerry Siegel and Joe Shuster.
In his first appearance, Jimmy was a nameless member of the Daily Planet press corps. He made his first named appearance in The Adventures of Superman, a radio show. He soon returned to regular comics, where his personality was expanded and developed upon. His first named appearance was in Superman #13, with his full name being revealed in Superman #15. He vanished from comics for about ten years before being revived in the early 1950s as part of a tie-in to the new Adventures of Superman television show.
Following from his 1953 revival, Jimmy was given his own title, Superman's Pal Jimmy Olsen. As was common in the Silver Age, the character's adventures during this time were in general eccentric and surreal, and tended towards the gorilla-related. During this era he had a fan club that implicitly had branches around the whole of the United States. During this era, Olsen is best remembered for his continual transformations into a variety of odd, variably powerful creatures for a variety of reasons. He has been transformed into Giant Turtle Boy, a giant turtle; Elastic Lad, whereby his elasticity was noticeably increased; and a gorilla, among a large number of other transformations.
Jack Kirby took over the title and began introducing elements from his Fourth World, such as Darkseid and early versions of the New Gods, and the DNA Project into Superman's Pal. Readership began to drop as he introduced elements such as the Loch Ness Monster and vampires into the canon, and he left the title as of issue #148. Shortly afterwards, with issue #163, Jimmy was absorbed into the Superman Family anthology label. At this point the character and his adventures took on a more serious bent, adopting the identity of "Mr Action" and working as an investigative reporter who dealt with crime and criminals in the city.
Jimmy has seen little modernization despite the total reboot of the DC Universe that took place following the Crisis on Infinite Earths. Major elements of his character remained the same, including his profession and friendship with Superman. Minor elements, such as his manner of dress, were different from earlier incarnations, but the impetus for these changes is rooted in the early Bronze Age. One significant change was the provenance of his signal watch, originally a gift from Superman, but in the Modern Age a creation of Jimmy himself. He briefly left his job at the Planet during the 1990s, and simultaneously underwent a personality change, becoming more arrogant and pushy. During this period he gained a job with Galaxy Broadcasters, which he soon lost after believing (falsely) that he had uncovered Superman's secret identity. After this brief absence, he regained his job with the Planet. Otherwise the character has remained largely stable.
Following the 2011 relaunch of the DC Universe, Jimmy Olsen remains a photographer for the Daily Planet. Clark Kent is his best friend, although Clark was working for another newspaper. Jimmy instead works together with Lois Lane and Miko on a majority of stories. Jimmy was also present at the demolition of the old Daily Planet building, over which he has expressed disappointment.
Major Story Arcs
During this story arc, Jimmy is briefly promoted to the Planet's star reporter. He assumes the job in place of Clark Kent, who had been demoted. Their relationship suffers because of the strain put on it by their changed relationship dynamic. After the One Year Later, however, Kent returns to his position as star reporter and Jimmy reverts to photography, at one point gaining a Pulitzer Prize for his work.
During the Countdown to Infinite Crisis, Jimmy Olsen becomes involved in the investigation into the murder of Duela Dent. He soon becomes inextricably tied with the Death of the New Gods when he starts inexplicably gaining a series of uncontrollable superpowers. He briefly takes up the mantle of Mr. Action, and attempts to assimilate himself into established superhero communities. However, they reject him and he soon abandons this pursuit. Instead he devotes himself again to an investigation into his powers, which is aided by Forager, who reveals that Jimmy has become the host for the souls of the New Gods. It is eventually revealed that this is because Darkseid is using Jimmy as a way station for powers he intends to use in his universe-conquering quest. When Jimmy returns to Earth following the failed attempt to eliminate the Morticoccus virus he is kidnapped by Mary Marvel, and his powers are taken control of by Darkseid, who causes him to emit Kryptonite radiation until his powers are rewired by Ray Palmer. Jimmy briefly battles Darkseid in a form reminiscent of his Giant Turtle Boy persona but is swiftly defeated. On the verge of being killed, Jimmy is saved when Ray Palmer intervenes again, destroying the New God power battery and returning Jimmy to his regular, unpowered state.

Travelling to the headquarters of Project Cadmus, he learns about the cloning that the Project has been carrying out for several years from Dubbilex, who dies after imparting this information. Jimmy next travels to the small town of Warpath in Arizona and interviews the sheriff, Greg Saunders. Soon Jimmy discovers that Saunders has been working with the only viable clone of the Guardian, and talks to the man. He returns to Metropolis soon after with the knowledge that a part of the US Military, going by the name " Project 7734," is plotting to destroy Superman. He contacts Erik Storn in the hope of gathering more information about this plot. However, he arrives too late, and finds a dying Erik in the wreckage of his burnt-out home. Erik dies in Jimmy's arms after telling him how to contact Natasha Irons. Irons explains the involvement of General Sam Lane in the plot and the existence of a planet killer. After gaining this information, Jimmy is confronted by Codename: Assassin, who has been following Jimmy throughout his investigation. He shoots Jimmy twice in the chest, and leaves him to drown in the ocean. However, Jimmy survives the attempt and uses the opportunity to fake his own death allowing him to carry out his investigation in secrecy.
