Tom Swift is the main character of five series of American juvenile science fiction and adventure novels that emphasize science, invention, and technology. First published in 1910, the series total more than 100 volumes. The character was created by Edward Stratemeyer, the founder of the Stratemeyer Syndicate, a book-packaging firm. Tom's adventures have been written by various ghostwriters, beginning with Howard Garis. Most of the books are credited to the collective pseudonym "Victor Appleton". The 33 volumes of the second series use the pseudonym Victor Appleton II for the author. For this series, and some of the later series, the main character is "Tom Swift, Jr." New titles have been published as recently as 2007. Most of the various series emphasized Tom's inventions. The books generally describe the effects of science and technology as wholly beneficial, and the role of the inventor in society as admirable and heroic.

The minstrel show, or minstrelsy, was an American form of entertainment developed in the early 19th century. Each show consisted of comic skits, variety acts, dancing, and music performances that depicted people specifically of African descent. The shows were performed by white people in make-up or blackface for the purpose of playing the role of black people. There were also some African-American performers and all-black minstrel groups that formed and toured under the direction of white people. Minstrel shows lampooned black people as dim-witted, lazy, buffoonish, superstitious, and happy-go-lucky.
Tom Swift Jr. is the central character in a series of 33 science fiction adventure novels for male adolescents, following in the tradition of the earlier Tom Swift ("Senior") novels.

It was decided that the protagonist of the new series would be the son of the earlier Tom Swift and his wife, Mary Nestor Swift; the original hero continued as a series regular, as did his pal Ned Newton. The covers were created by illustrator J. Graham Kaye. Covers in the later half of the series were mostly by Charles Brey. A total of 33 volumes were eventually published.
