School years
Siegel wrote for his school's weekly newspaper, The Glenville Torch. One of his known works for that newspaper was Goober the Mighty, a parody of Tarzan. Joseph Shuster provided illustrations for some of Siegel's Goober stories. This was their first known collaboration as writer and artist.[6]
Siegel also self-published a fanzine called Science Fiction: The Advance Guard of Future Civilization. In the third issue of this fanzine, he published a short story titled "The Reign of the Superman" under the pseudonym "Herbert S. Fine". The story is about a vagrant named Bill Dunn who gains vast psychic powers after taking an experimental drug. Dunn then calls himself "the Superman" and proceeds to use his powers maliciously.[25]
In 1933, Siegel and Shuster began making amateur comic strips together. They self-published their work in a fanzine titled Popular Comics.
DC Comics
Siegel and Shuster began working for DC Comics (then known as National Allied Publications) in 1935. Siegel's writing career there was interrupted in June 1943 when he was conscripted into the Army, though he continued to receive credit for stories written by ghostwriters.[26] After his discharge, he sued DC Comics for the rights to Superman and Superboy, and was consequently given no more freelance work from the publisher.[27] In 1959, he returned to DC as a writer, and was dropped again in 1967 when he again attempted to take back the copyright to Superman.[28]
During his first tenure at DC Comics (1935–1943), Siegel created the following characters:
During his second tenure at DC Comics (1959–1966), Siegel created several characters relating to the Legion of Super-Heroes, including members Bouncing Boy, Brainiac 5, Triplicate Girl, Invisible Kid, Matter-Eater Lad, Phantom Girl, and Chameleon Boy; and enemies Cosmic King, Lightning Lord, and Saturn Queen, who are part of the Legion of Super-Villains.
During his second tenure as writer at DC Comics, Siegel did not receive any byline for his stories, which was the normal policy of DC Comics at the time.

Funnyman
Siegel and Shuster conceived Funnyman, a clownish superhero, while they were still working for DC Comics. They anticipated a decline in the popularity of conventional superheroes, and thought a comedy hybrid character would have sustainable appeal. Unlike other characters they created, Siegel and Shuster were determined to retain the copyright to Funnyman. This was unacceptable to DC Comics, so they instead made a deal with Magazine Enterprises, a comic-book publishing company owned by Vin Sullivan. The series Funnyman lasted six issues, and a subsequent newspaper strip also was unsuccessful.[29] It was the last collaboration of Siegel and Shuster. By this time, Shuster's vision had deteriorated to the point he could not work.[30]
Marvel Comics
Siegel first worked for Marvel in 1963, under the pseudonym "Joe Carter". With Stan Lee, he co-created the villain Plantman (Strange Tales #113). He also scripted the "Human Torch" feature in Strange Tales #112–113 (Sept.–Oct. 1963), introducing the teenaged Torch's high school girlfriend, Doris Evans; and, under his own name, a backup feature starring the X-Men member Angel, which ran in Marvel Tales and Ka-Zar.[31] According to then-Marvel editor-in-chief Stan Lee, Siegel "was down on his luck" and in ill health at the time, so he gave him a job at Marvel as a proofreader, during which time Siegel wrote the Angel story.[32]
Archie Comics
Siegel worked for Archie Comics in 1966, on series including The Fly, The Mighty Crusaders, The Web, and Steel Sterling, all starring characters revived from the 1940s. Archie canceled its superhero line later that year, and Siegel was let go.
Fleetway Publications
Siegel became the main writer on The Spider a British comic book supervillain/superhero that appeared in anthology book Lion between 26 June 1965 and 26 April 1969[33] and was reprinted in Vulcan. Siegel took over the writing of the character with his third adventure, and would write the bulk of his adventures. His first work on the character was published in the 8 January 1966 issue, the start of the serial "The Spider v Doctor Mysterioso".[34][35] He also created and wrote Gadgetman and Gimmick-Kid.
Military magazines
When Siegel served in the Army (1943–1946), he was posted in Honolulu, Hawaii and wrote for Stars and Stripes, Midpacifican, and Yank, the Army Weekly, all military publications written by soldiers. In Stars and Stripes, he had a small humor column titled "Take a Break wit T/5 Jerry Siegel". In Midpacifican, he wrote the comic strip Super Sam, in which an Army private gains superpowers after receiving a blood transfusion from Superman. This was not authorized by DC Comics.
Miscellaneous
In 1956, Siegel created two superheroes for Charlton Comics: Mr. Muscles and Nature Boy. The series Mr. Muscles ran two issues, and Nature Boy three.[36]
In 1968, he worked for Western Publishing, for which he wrote (along with Carl Barks) stories in the Junior Woodchucks comic book.
He subsequently worked for the Italian comic Topolino published by Mondadori Editore (the Italian Disney comics licensee) from 1972 to 1979.[37][38] He was listed in the mastheads of the period as a scriptwriter ("soggettista e sceneggiatore").
In the 1980s, he worked with Val Mayerik on the feature "The Starling", which appeared in the comic book
