Cahn Auditorium (1940) is the largest performance space on campus, with more than 1,000 seats and an orchestra pit. One of the country's most famous college productions, the annual Waa-Mu Show (begun in 1929), is staged here, as are many other productions each year. The auditorium was named for civic leader Bertram Cahn, donor, trustee, alumnus (class of 1899), and chairman of the clothier B. Kuppenheimer and Company.
