Ian Kershaw

Sir Ian Kershaw (born 29 April 1943) is an English historian whose work has chiefly focused on the social history of 20th-century Germany. He is regarded by many as one of the world's foremost experts on Nazi Germany and noted for his biographies of Hitler.

Kershaw worked at the University of Sheffield. He has called German historian Martin Broszat an "inspirational mentor" who did much to shape his understanding of Nazi Germany. Kershaw has served as historical adviser on numerous BBC documentaries, notably ''The Nazis: A Warning from History'' and ''War of the Century''. Provided by Wikipedia
