Baum's education began with tutors at home in his early years. At the age of 12, he went to the Peekskill Military Academy. Baum left the school after a health crisis two years later, apparently suffering from some type of heart condition. Never earning a high school degree, he spent his early adulthood exploring his interest in acting and writing for the stage.
Lyman Frank Baum was born on May 15, 1856, in Chittenango, New York. In 1900, Frank Baum wrote one of the most famous works of children's literature, The Wonderful Wizard of Oz, later known as The Wizard of Oz. He enjoyed a comfortable upbringing as the son of a barrel factory owner who also had some success in the oil business. Named "Lyman" after an uncle, Baum hated his first name and chose to be called by his middle name "Frank" instead.
