William H. Prescott

William Hickling Prescott was an American historian and Hispanist, who is widely recognized by historiographers to have been the first American scientific historian. Despite having serious visual impairment, which at times prevented him from reading or writing for himself, Prescott became one of the most eminent historians of 19th-century America. He is also noted for his eidetic memory, also called "photographic memory".
