This period saw Illinois Tech as the largest engineering school in the United States, as stated in a feature in the September 1953 issue of Popular Science magazine. Illinois Tech housed many research organizations: IIT Research Institute (formerly Armour Research Foundation and birthplace of magnetic recording wire and tape as well as audio and video cassettes), the Institute of Gas Technology, and the American Association of Railroads, among others. Three colleges merged with Illinois Tech after the 1940 Armor/Lewis merger: Institute of Design in 1949, Chicago-Kent College of Law in 1969, and Midwest College of Engineering in 1986. Illinois Tech's Stuart School of Business was founded by a gift from Lewis Institute alumnus Harold Leonard Stuart in 1969, and joined Chicago-Kent at Illinois Tech's Downtown Campus in 1992; it phased out its undergraduate program (becoming graduate-only) after spring 1995. (An undergraduate business program focusing on technology and entrepreneurship was launched in fall 2004 and was for a while administratively separate from the Stuart School. It is now part of the school, but remains on Main Campus.) The Institute of Design, once housed on the Mies Campus in S.R. Crown Hall, also phased out its undergraduate programs and moved downtown in the early 1990s. Although not used in official communication, the nickname "Illinois Tech" has long been a favorite of students, inspiring the name of the student newspaper; (renamed in 1928 from Armour Tech News to TechNews), and the former mascot of the university's collegiate sports teams, the Techawks. During the 1950s and 1960s, the nickname was actually more prevalent than "IIT." This was reflected by the Chicago Transit Authority's Green Line rapid transit station at 35th and State being named "Tech-35th", but has since been changed to "35th-Bronzeville-IIT." In the 2010s, school administrators began a move to reintroduce the "Illinois Tech" nickname, to decrease confusion with the Indian Institutes of Technology that share the IIT abbreviation and with ITT Technical Institute whose abbreviation is similar. In June 2020 Illinois Tech launched the College of Computing and the revamped Lewis College of Science and Letters. The College of Computing houses the computer science, applied mathematics, and information technology and management departments, as well as the industrial technology and management program. The revamped Lewis College added the biology, chemistry, food science and nutrition, and physics departments to the remaining humanities, psychology, and social science departments.
