Miller's son-in-law DeWitt Hutchings, was used to recognize notable aviators, including Amelia Earhart. On March 20, 1942, World War I ace Eddie Rickenbacker was honored at the inn, becoming the fifty-seventh flier added to the monument. Today, 151 fliers or groups of fliers are honored by having their signatures etched onto copper wings attached to the wall. Frank Miller died in 1935 and the inn continued under the management of his daughter and son-in-law, Allis and DeWitt Hutchings, who died in 1956. The inn then went through a series of ownership changes and some of its older rooms were converted to apartments and used as dorms for UC Riverside. In the early 1960s, St. John's College considered buying it as a location for its western campus but abandoned negotiations when John Gaw Meem donated land in Santa Fe, New Mexico. In 1992, Owner Duane Roberts rescued The Mission Inn Hotel & Spa from the brink of demolition, resurrecting the property’s iconic Spanish Mission-style opulence while modernizing the hotel with comfort, technology, culinary, shopping, wedding, and spa amenities. His wife, Owner, Vice Chairman and Chief Operating Officer Kelly Roberts, oversees the AAA Four Diamond-rated Mission Inn and maintains its lofty hospitality standards. The couple brings to life annual events such as the Festival of Lights, Feste dell’Amore, the Pumpkin Stroll, as well as immersive additions like Conde Nast Kelly’s Spa and Boutique and dynamic culinary venues. Architecture With its widely varying styles, the Mission Inn was designed by multiple architects. Frank Miller selected Arthur Burnett Benton to design the original building. Miller chose Myron Hunt to design the Spanish Wing added to the rear of the main building. He later hired G. Stanley Wilson to design the St. Francis Chapel. Wilson also added a rotunda featuring circular staircases and a dome. Notable guests For 120 years, the Mission Inn has been the center of Riverside, host to U.S. Presidents, celebrities, a number of seasonal and holiday functions, as well as occasional political functions and other major social gatherings. Pat and Richard Nixon were married in what is now the Presidential Lounge, Nancy and Ronald Reagan honeymooned there, and eight other U.S. presidents have visited the inn: Benjamin Harrison, William McKinley, Theodore Roosevelt, William Howard Taft, Herbert Hoover, John Fitzgerald Kennedy, Gerald Ford, and George W.
