Tilman Nagel (born 19 April 1942, in Cottbus) is a German Orientalist and Professor Emeritus at the University of Göttingen. The author of numerous books including The Koran and Timor the Conqueror is recognized as one of the world's leading experts in Islamic Studies, particularly theology and history. His opus magnum, Mohammed: Life and Legend,[1] depicts the historic reality of the life of Mohammed separating it from the legendary, and draws from a rich array of sources of which many have not yet been translated into European languages. Reviewers consider this "monumental piece of research" to remain "highly relevant for decades to come".[2]
