Lyman Frank Baum (May 15, 1856 – May 6, 1919), known as L. Frank Baum, was an American author of children's books, best known for writing 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" novels, 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).
On May 5, 1919, Baum suffered a stroke. The following day he slipped into a coma but briefly awoke and spoke his last words to his wife, "Now we can cross the Shifting Sands." Frank died on May 6, 1919. He was buried in Glendale's Forest Lawn Memorial Park Cemetery. His final Oz book, Glinda of Oz, was published on July 10, 1920, a year after his death.
