The Spin Doctors of 19th-Century America. Embracing the emerging sciences of the age, 19th-century Americans thought they might be able to combine physiognomy (the science of reading faces) and the techniques of photography to uncover the true characters of leaders and statesmen. Joanna Cohen from Queen Mary, the University of London explores their efforts and the lessons for voters now. This event was recorded in front of an audience at the Free Thinking Festival at Sage, Gateshead on 01.11.14.
