Lyman Frank Baum (15 May 1856 - 6 May 1919) was a US author, poet, playwright, actor, and independent filmmaker best known today as the creator - along with illustrator WW Denslow - of one of the most popular books in US children's literature, The Wonderful Wizard of Oz. He wrote thirteen novel sequels, nine other fantasy novels, and a plethora of other works (55 novels in total (plus four "lost" novels), 82 short stories, over 200 poems, an unknown number of scripts, and many miscellaneous writings), and made numerous attempts to bring his works to the stage and screen. His works predicted such century-later commonplaces as television, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).
