Father Goose: His Book is a collection of nonsense poetry for children, written by L. Frank Baum and illustrated by W. W. Denslow, and first published in 1899. Though generally neglected a century later, the book was a groundbreaking sensation in its own era; "once America's best-selling children's book and L. Frank Baum's first success," Father Goose laid a foundation for the writing career that soon led to The Wonderful Wizard of Oz and all of Baum's later work.

Lyman Frank Baum was an American author best known for his children's fantasy books, particularly The Wonderful Wizard of Oz, part of a series. In addition to the 14 Oz books, Baum penned 41 other novels, 83 short stories, over 200 poems, and at least 42 scripts. He made numerous attempts to bring his works to the stage and screen; the 1939 adaptation of the first Oz book became a landmark of 20th-century cinema.
