Dorothy Gale in the context of "Wicked (musical)"

The Oz books form a book series that begins with The Wonderful Wizard of Oz (1900) and relates the fictional history of the Land of Oz. Oz was created by author L. Frank Baum, who went on to write fourteen full-length Oz books. Baum styled himself as "the Royal Historian of Oz" in order to emphasize the concept that Oz is an actual place on Earth, full of magic. In his Oz books, Baum created the illusion that characters such as Dorothy and Princess Ozma relayed their adventures in Oz to Baum themselves, by means of a wireless telegraph.

After Baum's death in 1919, publisher Reilly & Lee continued to produce annual Oz books, passing on the role of Royal Historian. Ruth Plumly Thompson took up the task in 1921, and wrote nineteen Oz books. After Thompson, Reilly & Lee published seven more books in the series: three by John R. Neill, two by Jack Snow, one by Rachel Cosgrove Payes, and a final book by Eloise Jarvis McGraw and Lauren Lynn McGraw. The forty books in Reilly & Lee's Oz series are called "the Famous Forty" by fans, and are considered the canonical Oz texts.

Judy Garland (born Frances Ethel Gumm; June 10, 1922 – June 22, 1969) was an American actress and singer whose career spanned four decades. She is known for her artistic range and strong contralto voice, working in a variety of genres including musicals, comedies and dramas. Her career and personal life, marked by both public fascination and private struggle, made her a cultural icon and gay icon.

Garland began her career at the age of two: performing with her two older sisters as a vaudeville act called the Gumm Sisters. In 1935, aged 13, she signed a contract with Metro-Goldwyn-Mayer (MGM) and was initially cast in supporting roles in ensemble musicals such as Broadway Melody of 1938 (1937) and Thoroughbreds Don't Cry (1937). She achieved international recognition for her portrayal of Dorothy Gale in the musical film The Wizard of Oz (1939). She followed this with leading roles in MGM musicals including Meet Me in St. Louis (1944), Easter Parade (1948), and Summer Stock (1950). She expanded her range with dramatic performances in A Star Is Born (1954) and Judgment at Nuremberg (1961), both of which earned her Academy Award nominations.
