Stephen G. Haw (b. 1951) is a botanical taxonomist and historian, specializing in subjects relating to China. He is the author of several published books and a large number of periodical articles. His most important work relates to the taxonomy of Tree Peonies and to the history of the Mongol period in East Asia. He has made a major contribution to studies of Marco Polo's account of East Asia: according to Peter Jackson, an authority on the history of the Mongol conquests, his book about Marco Polo "must surely now have settled the controversy surrounding the historicity of Polo's visit to China."
He studied Chinese at the University of Oxford (Wadham College), and took an M.A. at the University of London. He also studied at the University of Shandong in China. His first book, The Lilies of China, was published in 1986. He subsequently authored China: A Cultural History (1991), A Traveller’s History of China (first edition 1995; several subsequent editions), Broadleaved Evergreens (2001), Marco Polo's China (2006), and Beijing – A Concise History (2007). Of these, A Traveller’s History of China has been published in translations into Finnish, Swedish and Portuguese. One reviewer wrote of this book that it "is not the perfect solution to the problem of a single source for the prospective China tourist, but it is by far the best attempt at such a book I have yet seen."
His articles have appeared in many different periodicals, including the Royal Horticultural Society's publications The Garden and The Plantsman, Hortus, Country Life, The Edinburgh Journal of Botany, and Acta Phytotaxonomica Sinica. During the last few years, several important articles relating to the history of the Mongols in China have appeared in academic journals including the Journal of the Royal Asiatic Society, East Asian History, the Bulletin of the School of Oriental and African Studies, and the Journal of Asian History.
