Buck Rogers is a fictional character who first appeared in Armageddon 2419 A.D. by Philip Francis Nowlan in the August 1928 issue of the pulp magazine Amazing Stories as Anthony Rogers. A sequel, The Airlords of Han, was published in the March 1929 issue. Philip Nowlan and the syndicate John F. Dille Company, later known as the National Newspaper Syndicate, contracted to adapt the story into a comic strip. After Nowlan and Dille enlisted editorial cartoonist Dick Calkins as the illustrator, Nowlan adapted the first episode from Armageddon 2419, A.D. and changed the hero's name from Anthony Rogers to Buck Rogers. The strip made its first newspaper appearance on January 7, 1929. Later adaptations included a serial film, a television series (where his first name was changed from Anthony to William), and other formats. The adventures of Buck Rogers in comic strips, movies, radio and television became an important part of American popular culture. This pop phenomenon paralleled the development of space technology in the 20th century and introduced Americans to outer space as a familiar environment for swashbuckling adventure. Buck Rogers has been credited with bringing into popular media the concept of space exploration, following in the footsteps of literary pioneers such as Jules Verne, H.G. Wells, and Edgar Rice Burroughs.
