Michael Boro Petrovich was born in 1922 in Cleveland, Ohio, of Serbian and Croatian parentage. After completing undergraduate studies (and winning election to Phi Beta Kappa), he served for the last two years of World War II as an officer in the OSS, his postings including Yugoslavia in the post-War early-Tito era. While pursuing graduate study at Columbia (M.A. 1947, Ph.D. 1955) and study abroad, Michael was engaged as an instructor at the University of Wisconsin-Madison starting in the fall of 1950. He was made Assistant Professor in 1953; he rose to full professorship in 1960, and in 1982 was made Evjue-Bascom Professor of History. Along the way, he accumulated a daunting list of honors: the first Kiekhofer Memorial Teaching Award (1953), the E. Harris Harbison Award for Distinguished Teaching (1967), the Wisconsin Student Association Teaching Award (1969), an honorary degree, and a range of honors national and international. He was chosen to lead various organizations, or serve on councils, in his scholarly fields of Slavic, Russian, and Balkan studies. His prolific scholarly output totaled some 70 items over more than 40 years of publishing; he coauthored five textbooks (and was working on a high-school text when he died), and translated seven of the books of his old friend, the Yugoslav dissident Milovan Đilas.
