Why it's listed
Located on West 44th Street between Fifth and Sixth avenues in Manhattan, this seven-story building began in 1890 as the Berkeley School for Boys, designed by Lamb & Rich as a four-story Renaissance Revival structure. Its facade includes a frieze copied from the Parthenon, modeled on casts once held by the Metropolitan Museum of Art. The General Society of Mechanics and Tradesmen, founded in 1785, bought it in 1899. Between 1903 and 1905 architect Ralph S. Townsend removed the top story, added three new stories faced in yellow Roman brick, and built rear classroom wings, with Andrew Carnegie paying for the work. Inside are a marble lobby, a three-story library with a large skylight, a wrought iron staircase, and classrooms. The building houses the Mechanics' Institute, the Library, a museum with a lock collection, and a publishing center. It is recognized for its role in education and social history and for its architecture.
Significance in brief: The building has housed the General Society, founded in 1785, since 1899. It contains the Mechanics' Institute school, a library, and a museum serving working people's education. It is also significant as an architectural work by Lamb & Rich, with a major addition by Ralph S. Townsend funded by Andrew Carnegie.
