The college students needed separate quarters. In 1872 Saint Joseph Hall was erected for their use. The number students continued to increase, and the Laurentianum (the present Main Building) was built in 1881. All student activity was now separate from the friary, with the exception of the dining room. In 1886, at the urging of bishops in the Midwest, a commercial course was introduced into the college curriculum so that Catholic young men going into the business world would have a strong foundation in their Catholic faith.
