The Great Hall of The Cooper Union has stood for more than a century as a bastion of free speech and a witness to the flow of American History and ideas. When the hall opened in 1858, it quickly became a mecca for all interested in serious discussion and debate of the vital issues of the day.

The Great Hall was the platform for some of the earliest workers' rights campaigns and for the birth of the NAACP, the women's suffrage movement and the American Red Cross. To the Great Hall's podium has come a pageant of famous Americans – rebels and reformers, poets and presidents. Before they were elected, Presidents Lincoln, Grant, Cleveland, Taft and Theodore Roosevelt all spoke there.
