Frank Dikötter is the author of a series of brilliant and harrowing books about communist China. He is not only a prize winning historian of post war China but a highly engaging speaker. He talked about China from the time of the communist takeover after WWII all the way up to and beyond the death of Mao. The regime was responsible for the deaths of tens of millions and Frank does a great service in helping to keep the story of one of the greatest tragedies in history at the forefront of people's minds.
