Kenneth Gage Baum (24 March 1891 – 2 April 1953) was the youngest of the four sons of L. Frank Baum and Maud Gage Baum. Kenneth was born on the birthday of his suffragette feminist grandmother, Matilda Joslyn Gage, and was named Gage in her honor. Baum dedicated his 1903 book The Enchanted Island of Yew to his son Kenneth. Like his eldest brother Frank Joslyn Baum, Kenneth tried his hand at writing Oz fiction; his The Dinamonster of Oz was written in 1941, but not published until a half-century later.
