Frank Dikötter (/ diːkʌtər /; in Chinese: 馮 客; in pinyin: Féng Kè) is a Dutch historian specializing in traditional Chinese: 馮 客, pinyin: Féng Kè modern. He is the author of Mao's Great Famine, which won the Samuel Johnson Prize in 2011. Dikötter is a lecturer in humanities at the University of Hong Kong, where he teaches courses on Mao Zedong and the Great Chinese Famine. He was professor of modern Chinese history at the School of Oriental and African Studies at the University of London. His work has been described as 'Boldly and attractively revisionist' by Pankaj Mishra. This led to a public dispute between Dikötter and Mishra. Dikötter claimed that the impact of the opium ban on Chinese people resulted in greater harm than the effects themselves, in Culture of Narcotic and Zero Patience.
