The Wizard of Oz (1902 musical)
The Wizard of Oz was a 1902 musical extravaganza based on "The Wonderful Wizard of Oz" by L. Frank Baum, which was originally published in 1900. Much of the original music was by Paul Tietjens and has been mostly forgotten, although it was still well-remembered and in discussion at MGM in 1939 when the classic film version of the story was made. Although Baum is the credited bookwriter, Glen MacDonough was hired on as jokewriter after Baum had finished the script.
The Wonderful Wizard of Oz
Some critics have suggested that Baum may have been inspired by Australia, a relatively new country at the time of the book's original publication. Australia is often colloquially spelled or referred to as "Oz". Furthermore, in "Ozma of Oz" (1907), Dorothy gets back to Oz as the result of a storm at sea while she and Uncle Henry are traveling by ship to Australia. Like Australia, Oz is an island continent somewhere to the west of California with inhabited regions bordering on a great desert. One might imagine that Baum intended Oz to be Australia, or perhaps a magical land in the center of the great Australian desert.
