Cass Gilbert is perhaps best remembered as the architect of the Woolworth Building, for years the tallest building in the world. Yet his work also included such monumental public buildings as the U.S. Custom House in Lower Manhattan and many state capitols. He created ornate Classical buildings but was also a pioneer of the modern skyscraper. This small exhibition in the library showcases material from the Cass Gilbert Collection from New-York Historical's Library collection. It features early 20th century photographs, drawings, letters, brochures and ephemera from Gilbert's extensive collection of personal and professional papers.
