The historic Foundation Building of the Cooper Union was constructed between 1853 and 1859 under the design of the college’s namesake, Peter Cooper.
The Italianate brownstone building is the oldest extant structure in America to be framed with steel beams.
Fun fact: Cooper created room for an elevator shaft predating the invention, believing the technology would come along soon enough.
The building’s Great Hall has hosted many-a great speaker, including Mark Twain and presidents Lincoln, Grant, Cleveland, Taft, Theodore Roosevelt, Wilson, Clinton, and Obama.
