A refugee scholar translated Ibn Khaldun into English and studied hashish in Islam
Evidence
Franz Rosenthal (1914–2003) studied with Schaeder and Paul Kraus in Germany and acquired the traditional Orientalist grounding in philology, but he left Germany in 1938 after Kristallnacht and eventually became a professor in Yale. An excellent classicist who knew Homer and Hesiod by heart, he was a specialist in Graeco-Arabic studies and was the author of Der Fortleben der Antike im Islam (‘The Classical Heritage in Islam’, 1965). He was also a specialist in historiography and the translator into English of Ibn Khaldun’s historico-philosophical magnum opus, the Muqaddimah. He produced specialized studies of hashish and gambling in medieval Islam that make fascinating reading. — Robert Irwin, For Lust of Knowing, 445
