Harrison H. Rountree was a friend of L. Frank Baum, who in time became one of Baum's largest creditors.
Rountree was a Chicago businessman, president of the Turner Brents Works, a brass foundry. He was a son of Major John Hawkins Rountree, a prominent Midwestern politician and civic leader of his generation. Harrison Rountree was the brother-in-law of Chauncey L. Williams, one of Baum's first publishers at Way & Williams. Baum dedicated his 1898 book By the Candelabra's Glare to Rountree. Baum biographer Katharine Rogers describes Rountree as "a cheerful, optimistic businessman."
Rountree loaned money to Baum when Baum was financing his Fairylogue and Radio-Plays in 1908. The debts from that enterprise largely caused Baum's bankruptcy in 1911. In the arrangements that followed, Rountree was appointed the trustee of Baum's estate, and the royalties from Baum's books with Bobbs-Merrill (including The Wonderful Wizard of Oz) were transferred to Rountree to help pay Baum's creditors — one of the biggest of them being Rountree himself. Baum's widow Maud Gage Baum did not regain the rights to Wonderful Wizard until 1932.
Rountree also has a daughter named Dorothy; she has been discussed as a possible source for the name of Baum's primary heroine.
