Yale Kamisar began his distinguished career as a law professor in 1957 at the University of Minnesota Law School. For three years prior to joining the Minnesota faculty, Yale had been an associate with the Washington, D.C. law firm of Covington & Burling specializing in antitrust law. Understandably, Yale and Minnesota assumed that he would devote the major part of his research and teaching to antitrust. At that time, the study of criminal law was near the bottom of the hierarchy of law school topics, and so young faculty often were assigned the task of teaching criminal law as the price to pay for the privilege of joining the faculty. Criminal procedure had not yet become a separate topic in law schools' curriculums.
