The Wonderful Wizard of Oz is an American children's novel written by author L. Frank Baum and illustrated by W. W. Denslow, originally published by the George M. Hill Company in Chicago on May 17, 1900. It has since been reprinted on numerous occasions, most often under the title The Wizard of Oz, which is the title of the popular 1902 Broadway musical as well as the iconic 1939 musical film adaptation.
Baum dedicated the book "To my good friend & comrade, My Wife" Maud Gage Baum. In January 1901, George M. Hill Company completed printing the first edition, a total of 10,000 copies, which quickly sold out. The Wonderful Wizard of Oz sold three million copies by the time it entered the public domain in 1956.
Lyman Frank Baum (May 15, 1856 May 6, 1919), better known by his pen name L. Frank Baum, was an American author chiefly known for his children's books, particularly The Wonderful Wizard of Oz. He wrote thirteen novel sequels, nine other fantasy novels, and a host of other works (55 novels in total, plus four "lost works", 83 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 anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high risk, action-heavy occupations (Mary Louise in the Country), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).
