At that time, he was the father of two children and spent many years earning low wages, which forced Burroughs to start writing pulp fiction. His first story was “Under the Moons of Mars”, under the pseudonym Norman Bean, which Frank Munsey published in the February to July 1912 editions of The All-Story, a text that inaugurated the Barsoom series and first published as a book in 1917 in Chicago under the title “A Princess of Mars”. While completing his series he also completed “Tarzan of the Apes” and other novels. Burroughs also wrote popular science fiction, fantasy, western stories and historical novels, many published in All-Story and The Argosy. After great success with his best sellers, in 1923 Burroughs created Edgar Rice Burroughs, Inc. and began printing his own books until the 1930s.
