General Patrick Hurley opened the Ambassador Hotel in 1929, intending it to be a luxury “extended stay” residence for Tulsa businessmen (mostly oil business top executives), who were building mansions that were not yet ready for occupancy. Hurley never stayed in the hotel he founded. He moved to Washington, D. C. in March 1929, after President Herbert Hoover chose him to be Secretary of War, after the death of the previous Secretary, who died in December 1929. Hurley never returned to Tulsa.
