Warren Weaver Hall, ca. 1975.

Upon its completion in 1965, the New York Times described New York University’s Warren Weaver Hall as “the largest mathematics and teaching center in the world.” Designed by the firm Warner, Burns, Toan and Lunde; Weaver Hall replaced “light manufacturing buildings” on Mercer, West 3rd and 4th Streets, and the former 15th Precinct police station at No. 251 Mercer.
