in the business, and Siegel and Shuster had given away the copyrights to their previous works as well (see the Copyright issues section of this article for more details on this matter). The duo's revised version of Superman appeared in the first issue of Action Comics, which was published on April 18, 1938. The issue was a huge success thanks to Superman's feature. Influences Siegel and Shuster read pulp science-fiction and adventure magazines, and many stories featured characters with fantastical abilities such as telepathy, clairvoyance, and superhuman strength. One character in particular was John Carter of Mars from the novels by Edgar Rice Burroughs. John Carter is a human who is transported to Mars, where the lower gravity makes him stronger than the natives and allows him to leap great distances. Another influence was Philip Wylie's 1930 novel Gladiator, featuring a protagonist named Hugo Danner who had similar powers. Superman's stance and devil-may-care attitude were influenced by the characters of Douglas Fairbanks, who starred in adventure films such as The Mark of Zorro and Robin Hood. The name of Superman's home city, Metropolis, was taken from the 1927 film of the same name. Popeye cartoons were also an influence. The name "Clark Kent" was created by taking the first names of actors Clark Gable and Kent Taylor. "Clark" was also inspired by explorer William Clark especially when coming up with the names "Lois and Clark" a nod to Meriwether Lewis and William Clark, American explorers who discovered the Pacific Ocean. Clark Kent's harmless facade and dual identity were inspired by the protagonists of such movies as Don Diego de la Vega in The Mark of Zorro and Sir Percy Blakeney in The Scarlet Pimpernel. Siegel thought this would make for interesting dramatic contrast and good humor. Another inspiration was slapstick comedian Harold Lloyd. The archetypal Lloyd character was a mild-mannered man who finds himself abused by bullies but later in the story snaps and fights back furiously. Kent is a journalist because Siegel often imagined himself becoming one after leaving school. The love triangle between Lois Lane, Clark, and Superman was inspired by Siegel's own awkwardness with girls. The pair collected comic strips in their youth, with a favorite being Winsor McCay's fantastical Little Nemo. Shuster remarked on the artists who played an important part in the development of his own style: "Alex Raymond and Burne Hogarth were my idols
