This week we're celebrating International Women's Day with a special episode looking at the role of women in the early days of Chatham House. Katharina Rietzler is a historian at the University of Sussex, and co-leads a Leverhulme-funded project titled 'Women and the History of International Thought.'  Ben met up with Katharina to find out more about how women experienced work at the institute from its founding to the end of the Second World War.  Find out more: 'Women and the History of International Thought' project
