The campus was named "Indiana University South Bend" in 1968. The first master's degrees were conferred in 1970. Enrollment exceeded 5,000 in 1971, and the addition to Northside Hall was opened in 1972. The purchase of the Associates Building (now known as the Administration Building) was completed in 1975. Groundbreaking for the Franklin D. Schurz Library was in 1986, and it opened in 1989. Chancellor Wolfson retired in 1987 and H. Daniel Cohen was named chancellor. Cohen concentrated on improving facilities, grounds, and programming. In 1994, the university purchased the former Playland Park, a 26.5-acre parcel on the south side of the St. Joseph River. Playland had been an amusement park, a golf course, and a ballpark. Cohen resigned in 1995 as a result of sexual harassment allegations against him, and long-time history professor, Lester C. Lamon, assumed the position of acting chancellor for two years until Kenneth L. Perrin was named chancellor.
