Dr Daniel Larsen

Temporary Lecturer


I previously held a Junior Research Fellowship at Trinity College, Cambridge. My MPhil and PhD degrees are from Christ's College, Cambridge, and I previously completed my BA at the University of Nebraska-Lincoln.

Research Interests

My research interests are principally in American and British foreign policy and intelligence, particularly in the first half of the twentieth century.

 I have focussed especially on Anglo-American relations and British war policy in the First World War era, with an emphasis on the role of British intelligence. My first book, Plotting for Peace, is forthcoming with Cambridge University Press, and it re-examines American peace diplomacy and the British diplomatic and political response to it during 1914 to 1917.  I am especially interested in the role of codebreaking in shaping foreign policy, the role of secrecy in diplomacy, and I am currently moving into the area of international economics and finance and its importance in Anglo-American wartime relations.


I am co-convenor for POL14 "U.S. Foreign Policy", during 2019-2020.  I am also a Temporary College Lecturer in History at Trinity College.
