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 totals 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. Translated into many languages, the books have sold more than 30 million copies worldwide. Tom Swift has also been the subject of a board game and several attempted adaptations into other media. Tom Swift has been cited as an inspiration by various scientists and inventors, including aircraft designer Kelly Johnson.
