Erik Linstrum is a historian of modern Britain in its imperial and global contexts. His research explores the politics of knowledge and the circulation of information, with particular interests in science and technology, war and violence, and the long history of decolonization. His first book, Ruling Minds: Psychology in the British Empire, won the George Louis Beer Prize of the American Historical Association for the best book of the year in European international history. He is currently writing a history of knowledge about colonial violence in post-1945 Britain. Tentatively titled Age of Emergency, it traces reports of atrocities in Malaya, Kenya, and Cyprus as they circulated through British society: from the anticolonial left to the unabashedly imperialist right, from Fleet Street to the Church of England, from veterans' associations to the British Red Cross, from BBC teleplays to the West End theater scene.
