I visited E.P. and Dorothy Thompson at their home in Worcestershire in December 1991 to record their memories of their years in the Communist Party for a radio series I was making about the international Communist movement - the audio of the series is available here. The original audio cassettes are part of a personal archive now deposited at the National Sound Archive. The audio of both interviews is posted elsewhere on this site - with permission - along with a transcript of the interview with Edward Thompson. I will also transcribe the interview with Dorothy Thompson in due course.
Edward and Dorothy's daughter Kate has set up a wonderful website about her parents with much more information and a bibliography: www.edwardanddorothythompson.com
