Tilman Nagel (born 19 April 1942, in Cottbus) is a German Orientalist and Professor Emeritus at the University of Göttingen. He is the author of books including The Koran and Timor the Conqueror. His book, Mohammed: Life and Legend,[1] depicts what he sees as the historic reality of the life of Muhammad. One reviewer considers this "monumental piece of research" to remain "highly relevant for decades to come".[2]
