After massive war production, Pittsburgh labored to eliminate the 1930s image of an unsophisticated mill town. During the 1950s and 1960s Renaissance I began, a $500-million program to clean the city's air and develop new structures such as Gateway Center, the Civic Arena, and Point State Park. The late 1970s and early 1980s ushered in Renaissance II, a $3-billion expansion program reflecting the movement away from industry and toward high technology.
Today Pittsburgh has completed this dramatic shift from industry to a diversified base including high technology, health care, finance, and education, and continues its transition to a services-oriented city.
Pittsburgh's cultural personality is expressed by the Pittsburgh Symphony Orchestra, Pittsburgh Opera, Pittsburgh Ballet, Phipps Conservatory, and the Carnegie Museums of Pittsburgh, which include the Museum of Natural History and the Museum of Art. The city has 25 parks, 45 "parklets," 60 recreation centers, and 27 swimming pools.
Born of frontier warfare in the shadow of Fort Pitt, the city is named after the elder William Pitt, the great British statesman. Its strategic military position was an important commercial asset and Pittsburgh soon became a busy river port and transit point for the western flow of pioneers.
Industry grew out of the West's need for manufactured goods; foundries and rolling mills were soon producing nails, axes, frying pans, and shovels. The Civil War added tremendous impetus to industry, and by the end of the war, Pittsburgh was producing half the steel and one-third of the glass made in the country. Such captains of industry and finance as Thomas Mellon, Andrew Carnegie, and Henry Clay Frick built their industrial empires in Pittsburgh. The American Federation of Labor was born here (1881); the city has been the scene of historic clashes between labor and management.
World War I brought a fresh boom to the city, as well as changes in its industrial character. It was a vast arsenal for the Allies during World War II.
