Miriam Camps (1916-94) was a US diplomat, journalist, economist and scholar. Involved in the design of early post-war European integration organisations at the State Department in the 1940s, she remained at the centre of US foreign policy formulation towards Europe until the late 1960s. Her practical experience as a formal and informal diplomat – from the late 1950s Camps was affiliated with elite foreign policy think tanks – informed her output as a scholar. Like other female international thinkers and experts, she was well-known in her time, but her contribution both to US foreign policy and scholarship on European integration has since been largely overlooked by historians of European integration and IR scholars. This article explores Camps’ scholarship and her contribution to the field of European Studies. It asks why we know so little about Camps and advocates revisiting early European integration research and integrate individuals with more variegated careers into the founding history of the discipline.
