This book examines the effect of exile and internment on the intellectual development of the young Hans Keller, setting his personal story in the context of what is still a too-little-remembered part of British wartime history. It includes several important Keller texts, including that of his famous broadcast describing his escape from Nazi-occupied Vienna, together with his letters from British internment camps, set within the wider story of what was going on outside, where an intense political debate was taking place during Britain’s ‘finest hour’ about the rights of the individual in times of national emergency. The final section of the book shows the profound effect on Keller of his enforced change of language and culture, as he rediscovered his Viennese heritage through the very different culture of 1940s London.
