In the year 1940, Armour Institute and Lewis Institute merged in Chicago to create the Illinois Institute of Technology. The merging of these two schools called for a new master plan for the university, and Mies van der Rohe was commissioned for the job. Mies’ plan for the IIT campus was one of the largest projects he ever conceived and he developed it for twenty years. Today the campus contains 20 of his works, including the famous Crown Hall.
