E.M. Rose is an historian and expert in medieval history. Dr.Rose has taught at Johns Hopkins University, Villanova University, Princeton University, and Baruch/CUNY. "Blood libel," the myth that Jews engaged in ritual murder, originated in a suspenseful story of murder, a notorious trial that followed, and the ruthless ecclesiastical politics of Medieval Europe. In the first full telling of this dramatic story, The Murder of William of Norwich: The Origins of the Blood Libel in Medieval Europe (Oxford University Press, July 2015) E.M. Rose reveals how a false myth can arise from cold-blooded political intrigue and change history.
