Tim Hochstrasser is Associate Professor of International History at LSE where he lectures on early modern European history, culture and political thought. He was educated and has taught at the Universities of Cambridge and Oxford. He is particularly interested in the Enlightenment era of European Thought but believes that the relationship between events and ideas can only be fully understood by taking seriously the architecture, town planning, design, art history and music within any period. He tries to reflect this holistic approach to history in his writings and teaching. He has lived and worked in London for many years and regularly takes groups of students out on London walks and expeditions to galleries so that they can experience the material culture of history first hand.
