William of Newburgh
William of Newburgh (1135-1198) was a historian in the Yorkshire area, England. His major work was Historia rerum anglicarum which he saw as being historically accurate unlike Geoffrey of Monmouth's History of the British Kings, which he attacks. He has been called "the father of historical criticism". For all his accuracy, his work contains stories of local vampires, as does the fanciful work of Walter Map, his southern contemporary.
