The Mayo brothers and the 1925 opening
John D. Mayo and Cass A. Mayo were brothers from Iowa who arrived in Tulsa in the early 1900s and built fortunes in oil and real estate during the boom years. By 1923 they had decided to build a hotel that would establish Tulsa as a sophisticated American city rather than a frontier oil town. They hired Chicago architect George Winkler and the New York firm of Schmidt, Garden & Martin to design what they specified should be among the finest hotels west of the Mississippi.
Construction took two years and cost roughly $3 million — about $55 million in today's dollars — for an 18-story Renaissance Revival tower with 600 guest rooms. The hotel opened to public reception on May 25, 1925 with a gala that drew Oklahoma's political leadership, the state's leading oil-boom families, and visiting dignitaries from Tulsa's sister cities. The Mayo became Oklahoma's tallest building on opening day and held the title until the Philtower opened across the street in 1928.
The Mayos themselves operated the hotel for decades. The family kept the property running through the Great Depression, World War II, and the postwar years, maintaining the Mayo's reputation as Tulsa's premier hotel through changing economic cycles. The hotel was sold out of family hands in the 1960s and changed owners several times before closing entirely in 1981.
