Lyman Frank Baum [May 15, 1856-May 6, 1919] wrote the dialogue for the stage version of 'The Wizard of Oz'. Baum was the author and originator of the series on the royal histories of Oz. He also was involved most closely in the first and most famous staging of his book as a play, in 1902/1903.

The Wizard of Oz was a musical play.

The leader of the winged monkeys. The name isn't mentioned within the book, the 1939 film, or the 1902-1903 stage versions of The Wizard of Oz. But the name does appear at the end of the 1939 film, in the credits, as the leader of the flying monkeys.

If Dorothy Gale has ever had a middle name, nobody has ever written it down or shared it. L. Frank Baum, the writer who created her in 1900, didn't even give her a last name in The Wonderful Wizard of Oz (she got it in the 1902 stage play The Wizard of Oz, and it made its debut in the books in the third Oz book, Ozma of Oz, in 1907). He never gave her a middle name, nor told us the names of her parents.
