Cooper Union

This building was specially designed to house Peter Cooper's great philanthropy- a trade school for boys in New York who could not otherwise afford such specialized training. It is notable for the early use of rolled-iron sections produced by Cooper, Hewitt & Co. at Trenton Jersey- Cooper's own rolling mills. Cooper put off the completion of the school to roll beams for Astor's new library on Lafayette Street and for Harper & Brothers' publishing house on Franklin Square.
