Massachusetts Institute of Technology, also known as MIT, is an American private research university located in Cambridge, Massachusetts, United States. MIT has five schools and one college, containing a total of 32 academic departments, with a strong emphasis on scientific and technological education and research.

Founded in 1861 in response to the increasing industrialization of the United States, the institute adopted the European polytechnic university model and emphasized laboratory instruction from an early date. MIT's early emphasis on applied technology at the undergraduate and graduate levels led to close cooperation with industry. Curricular reforms under Karl Compton and Vannevar Bush in the 1930s re-emphasized basic scientific research. MIT was elected to the Association of American Universities in 1934. Researchers were involved in efforts to develop computers, radar, and inertial guidance in connection with defense research during World War II and the Cold War. Post-war defense research contributed to the rapid expansion of the faculty and campus under James Killian.
