For many years Lyn Smith has been recording the experiences of Holocaust survivors for the Imperial War Museum Sound Archive. In Forgotten Voices of the Holocaust, she has used these and other interviews to piece together this powerful oral history of how the Nazi regime murdered over six million European Jews, as well as Communists, Poles, Jehovah's Witnesses, homosexuals, people with disabilities, Soviet Prisoners of war and much of the Sinti Roma (Gypsy) population.
