In February 1945, the ‘Big Three’ met for arguably the most important and controversial of the conferences of the Second World War. At the Yalta Conference, Franklin D. Roosevelt, Winston Churchill and Joseph Stalin discussed the post-war reorganisation of Europe. The British and American leaders had come a long way to cooperate with Stalin, but they had not come alone. Roosevelt’s daughter, Anna, Churchill’s daughter Sarah and Kathleen Harriman, the daughter of the US ambassador to the Soviet Union were all in attendance. For her new book, Catherine Grace Katz has approached the Yalta conference from the perspective of these women, each of whom had a different angle and role there. In this episode Catherine shares her understanding of each of these women and what this can, in turn, tell us about the relationships between the United States, Britain and the USSR.
