Niall Ferguson (born April 18, 1964, in Glasgow) is a British historian. He specialises in financial and economic history as well as the history of empire. He is the Laurence A. Tisch Professor of History at Harvard University and the William Ziegler Professor of Business Administration at Harvard Business School. He was educated at the private Glasgow Academy in Scotland, and at Magdalen College, Oxford.
He is best known outside academia for his revisionist views rehabilitating imperialism and colonialism; within academia, his championing of counterfactual history is a subject of some considerable controversy. In 2008, Allen Lane published his most recent book, The Ascent of Money: A Financial History of the World which he also presented as a Channel 4 television series.
Ferguson is also a Senior Research Fellow of Jesus College, Oxford University and a Senior Fellow of the Hoover Institution, Stanford University. He is a resident faculty member of the Minda de Gunzburg Center for European Studies. In addition, Ferguson is an advisory fellow of the Barsanti Military History Center at the University of North Texas.
