====The Foundation Building====
Cooper Union's Foundation Building is an Italianate [[brownstone]] building designed by architect [[Fred A. Petersen]], one of the founders of the [[American Institute of Architects]]. It was the first structure in New York City to feature rolled-iron [[I-beam]]s for structural support; Peter Cooper himself invented and produced these beams.<ref name="wsj-2009-06-30">{{cite news |last=Hechinger |first=John |url=https://www.wsj.com/articles/SB124631610981670647 |title=One College Sidesteps the Crisis |work=The Wall Street Journal |date=June 30, 2009 |page=c1}}</ref> Petersen patented a fire-resistant hollow brick tile he used in the building's construction.<ref name="Zuravicky2002">{{cite book|first=Orli|last=Zuravicky|title=New York and the New Nation|url=https://books.google.com/books?id=ulfhnhW9zTMC&q=Fred+A.+Petersen+Cooper+Union&pg=PA24|date=August 2002|publisher=Rosen Classroom|isbn=978-0-8239-8408-4|page=24}}</ref><ref name=di>{{cite web|url=http://www.di.net/articles/architects-concrete-contributions/|title=Architects' Concrete Contributions|work=di.net|access-date=September 13, 2015}}</ref>  The building was the first in the world to be built with an elevator shaft, because Cooper, in 1853, was confident an elevator would soon be invented.
