U.S. Congress House Unamerican Activities Committee travelled to Seattle for three sets of hearings in the mid 1950s, demanding testimony from suspected Communists and threatening to imprison those who refused to answer questions about their own political activities and the lives of others. Here is the complete record of these investigations including testimony by John Daschbach, Eugene Dennett, Barbara Hartle, Louise Hatten, Burt Nelson, Julia Ruttillia, Clayton VanLydegraf, and others.
