The Engineering Quadrangle was dedicated on October 13, 1962. Built at a cost of approximately $8 million with funds derived largely from the $53 million campaign, the Quadrangle consists of six interconnecting halls surrounding a central court, located on Olden Avenue between Nassau Street and Prospect Avenue on land formerly a part of the old University Field. The Quadrangle, whose floor area is the equivalent of that of seven Nassau Halls, contains 120 laboratories for research and instruction, over 125 faculty offices and graduate study spaces, 25 classrooms, a research library, a general purpose machine shop, and a lounge and convocation room. It was designed by the architectural firm of Voorhees, Walker, Smith, Smith and Haines.

Five of the halls, devoted to teaching and research, are named for faculty and alumni: John Maclean, Sr., Princeton's first professor of chemistry; John Thomas Duffield, Professor of Mechanics and Mathematics; Cyrus Fogg Brackett, founder of the department of electrical engineering; George Erle Beggs, Professor of Civil Engineering; and James E. Hayes, C.E. 1895 and E.E. 1897. The sixth unit, the library, is named for the class of 1900, which made the principal gift for its construction. The court at the center of the quadrangle is named for architect Stephen F. Voorhees '00, a university trustee.
