In Summer 1972, UW–Parkside runner Lucien Rosa competed in the Olympic marathon in Munich, representing his home country of Ceylon (now Sri Lanka). He later became the head men's cross country and track coach at the university. In September that year, the Library/Learning Center and the Physical Education Building opened to the public. The library's collection included 200,000 books and 1,700 periodicals, and later grew to include more than 365,000 volumes, 1,680 periodicals, 4,720 maps and 11,600 audio/visual titles. In March 1973, assistant life sciences professor Omar Amin discovered a new species of tiny parasitic worm in the Pike River and named it "Acanthocephalus parksidei" after the university. In June the same year, the first UW–Parkside Alumni Association was founded, for the around 1,200 alumni of the university.
