Overview
Omni William Penn Hotel is a historic hotel at 530 William Penn Place on Mellon Square in downtown Pittsburgh, Pennsylvania. The 23-story property, which also has three underground levels, opened on March 11, 1916, after being built between 1915 and 1916. Contemporary newspapers presented it as one of the grandest hotels in the nation. Its first-night program was the annual Pittsburgh Chamber of Commerce gala, hosted by U.S. Secretary of State Philander Knox and described at the time as the largest gala in Pittsburgh's history. The hotel was originally developed by the Pittsburgh Hotel Company and occupied the western half of its downtown block. In 1928 it was acquired by the Eppley Hotel Company. Eugene Eppley financed a major 1929 expansion that filled the eastern half of the block, increased capacity to approximately 1,600 rooms, and added an Art Deco ballroom associated with designer Joseph Urban. The enlarged property was described as the second-largest hotel in the world. The hotel's scale reflected Pittsburgh's importance as an industrial, commercial, political, and transportation center during the early twentieth century. The property experienced several ownership and management changes during the following decades. Economic pressures during the Great Depression weakened Eppley's control, and Statler Hotels managed the hotel from 1940 to 1951. Eppley later regained control and resumed management in 1952. On June 4, 1956, the Eppley Hotel Company sold the property to Sheraton Corporation in a transaction described as one of the largest hotel sales in United States history at that time. The hotel became the Penn-Sheraton Hotel. Sheraton sold it in 1968 to Nomarl, a group of local investors, after which the William Penn name returned. Nomarl reduced the number of operating rooms as demand for downtown hotel accommodation declined, with some unused rooms converted into dormitory space for Duquesne University. Alcoa acquired the property in 1971. In 1984, Alcoa engaged Westin Hotels to manage the property. Following a reported $20 million renovation, the hotel operated as the Westin William Penn, with capacity reduced from roughly 840 rooms to approximately 650. Omni Hotels & Resorts ultimately acquired the property, and it was renamed Omni William Penn on January 31, 2001. It remains an operating Pittsburgh hotel and a member of Historic Hotels of America, the National Trust for Historic Preservation's recognition program for historic hotels. The hotel's significance extends beyond accommodation. Its public rooms have hosted political speeches, business conventions, scientific meetings, labor gatherings, campaign events, presidential visits, and cultural programs. Notable guests and speakers associated with the property include John F. Kennedy, Harry S. Truman, Dwight D. Eisenhower, Lyndon B. Johnson, George C. Marshall, Herbert Hoover, Richard Nixon, Gerald Ford, Ronald Reagan, Walter Mondale, and Adlai Stevenson. The hotel is also associated with entertainment history: Count Basie and his orchestra performed at the Chatterbox in the 1930s, and the staff reportedly helped innovate the bubble machine later made famous through Lawrence Welk's television performances. In 1934, Bob Hope is said to have made a marriage proposal at the hotel. A major surviving hospitality feature is the Terrace Room, a restaurant dating to 1916. It includes a wall-length mural depicting the taking of Fort Pitt. The hotel's large event spaces and historic interiors support lodging, dining, weddings, conferences, and civic functions. Its identity is therefore based on a combination of historic preservation, full-service hospitality, downtown convention use, and Pittsburgh heritage rather than on a consumer product line. The property was listed on the National Register of Historic Places in 1985.
History
The William Penn Hotel was constructed from 1915 to 1916 in downtown Pittsburgh, facing what is now Mellon Square. It opened on March 11, 1916, with the Pittsburgh Chamber of Commerce gala. The event, hosted by Secretary of State Philander Knox, was reported as the largest gala held in Pittsburgh up to that point. The original building occupied the western half of the block and was designed as a major urban hotel for Pittsburgh's expanding industrial and commercial economy. The Pittsburgh Hotel Company was the original owner. In 1928, the property was sold to the Eppley Hotel Company. Eugene Eppley financed a substantial enlargement in 1929, extending the hotel across the rest of the block. The project increased capacity to about 1,600 rooms and added an Art Deco ballroom associated with designer Joseph Urban. The enlarged hotel was described as the second-largest in the world, reflecting the scale of convention and business travel expected in Pittsburgh during the period. The Great Depression disrupted Eppley's control of the hotel. Statler Hotels managed the property between 1940 and 1951. Eppley regained a controlling interest during the early 1950s and resumed direct management on January 1, 1952. On June 4, 1956, the Eppley Hotel Company sold the hotel to Sheraton Corporation. The property was renamed the Penn-Sheraton Hotel as part of Sheraton's operating portfolio. Sheraton sold the hotel on May 22, 1968, to Nomarl, a group of local investors, for a reported $7.75 million. The original William Penn identity was restored. As demand for downtown hotel rooms declined, Nomarl reduced the operating room count from approximately 1,300 to 900 and made some unused rooms available as dormitory space for Duquesne University. Alcoa acquired the hotel in 1971. Alcoa brought Westin Hotels into the property in 1984. A reported $20 million renovation accompanied the change, and the hotel became the Westin William Penn. The renovation and subsequent operating strategy reduced the hotel from approximately 840 rooms to 650. The building was listed on the National Register of Historic Places in 1985. Omni Hotels & Resorts eventually acquired the property. On January 31, 2001, it was renamed Omni William Penn Hotel, the name it continues to use. The property is also a member of Historic Hotels of America, a program of the National Trust for Historic Preservation. Throughout its history, the hotel has functioned as a venue for political, civic, scientific, labor, business, and cultural gatherings. Events associated with the property include a 1921 banquet honoring Marshal Ferdinand Foch; the formation meeting of the Institute of Transportation Engineers in 1930; a 1937 engagement by Count Basie and his orchestra; a 1938 announcement connected with Point State Park and Pittsburgh's planned urban renaissance; a 1942 United Steelworkers conference; speeches by Harry S. Truman and George C. Marshall; the first Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy in 1950; the 1960 World Science Fiction Convention; and campaign and presidential appearances from the 1950s through the 1980s. From 1939 through the 1960s, it also hosted the region's annual Dapper Dan Sports Awards Banquet. The hotel is known for its historic hospitality spaces, particularly the Terrace Room restaurant, which dates to 1916 and contains a wall-length mural portraying the taking of Fort Pitt. Its historical associations include stays by prominent political figures, Bob Hope's 1934 marriage proposal, and the development of a bubble-machine concept later associated with Lawrence Welk. Today, the property operates as a full-service downtown hotel with guest rooms, restaurants, meeting rooms, ballroom facilities, and wedding and conference services.
