UPDATE: Here's an excerpt from the obituary released by the Genovese family:
Eugene Dominick Genovese, preeminent scholar of slavery and the master class in the American South, died on the morning of September 26th, 2012, after a long illness. Born in 1930, he graduated from Brooklyn College (1953) and Columbia University (1955, 1959) and taught at Rutgers University; Sir George Williams University in Montreal, Canada; the University of Rochester; the College of William and Mary, and a coalition of Georgia universities—Emory, Georgia Tech, Georgia State, and the University of Georgia. Ranking with the most influential historians of his generation, he also had appointments at Cambridge (as Pitt Professor), Princeton, Yale, and Columbia, was recipient of an honorary doctorate from the University of North Carolina at Chapel Hill, and served as president both of the Organization of American Historians and of The Historical Society, which he helped found.Read on here, at HNN.
