Klaus Tenfelde (1944–2011)
Klaus Tenfelde, in recent decades Germany’s most influential historian of labour and the working class, died on 1 July 2011, just seven weeks after he had retired from “his” Institute for Social Movements at the Ruhr University Bochum. In retirement, Tenfelde had hoped to continue work on his substantial “History of the Ruhr”, but a deceptive illness prevented it. Tenfelde is survived by his wife, Ellen and their two children.
