A 40-minute interview with Sir Geoff Palmer, OBE, Professor Emeritus in the School of Life Sciences at Heriot-Watt University in Edinburgh, and a leading human rights activist. The discussion covers issues such as Sir Geoff's use of archives to tell the story of Henry Dundas's role in delaying the abolition of slavery by fifteen years; resistance of contemporary historians towards a new interpretation of events using a scientific approach; and the importance of documentary evidence to refuting those who seek to downplay or deny crimes against humanity.
