Business Administration/Adel Mathematics
Arizona State College at Flagstaff constructed the Business Administration Building in 1962 for $800,000 in the postwar International architecture style. This structure housed the first computer on campus in 1964 and also had an apartment located on the south end that housed Northern Arizona University (NAU) presidents and guests during the 1960s.
In 1981, NAU renamed the structure the Educational Psychology Building after Business Administration moved to South Campus. Then in 1984, the university renamed it the Adel Mathematics Building, after Arthur Adel, a long-time NAU astronomer, mathematician, astrophysicist, and professor emeritus of science and mathematics. Since its opening, Adel Mathematics has undergone minor structural changes, such as the addition of an elevator, but has otherwise remained the same.
