During the academic year 1965-66, at the height of the civil rights movement, the University of Michigan Law School faculty looked around and saw not a single African-American student. The absence of any black students was not, it should hardly need saying, attributable to a policy of purposeful exclusion. A black student graduated from the Law School as early as 1870, and in the intervening years a continuous flow of African-American students, though not a large number, had been admitted and graduated. Some went on to distinguished careers in the law.
