Jan Marius Romein (30 October 1893 – 16 July 1962) was a Dutch historian, journalist, literary scholar and professor of history at the University of Amsterdam. A Marxist and a student of Huizinga, Romein is remembered for his popularizing books of Dutch national history, jointly authored with his wife Annie Romein-Verschoor. His work has been translated into English, German, French, Italian, Polish, Indonesian and Japanese. Biography Born in Rotterdam, Romein married the writer and historian Annie Romein-Verschoor (1895–1978) on 14 August 1920. Romein began writing while studying humanities at the University of Leiden (1914–1920). Of his professors the historian Johan Huizinga inspired him the most. During his studies and impressed by the First World War and the Russian Revolution he became interested in Marxism. He translated Franz Mehring's biography on Karl Marx into Dutch (1921; with an introductory essay). After a stay of seven months in Denmark, where Romein's friend and former fellow student Hans Kramers had become the assistant of the physicist Niels Bohr, the couple moved to Amsterdam in 1921. Romein became an editor of the daily De Tribune of the young Communistische Partij Holland (CPH, Communist Party of Holland). In addition, he worked as a freelance writer and translator. Already in 1916-1918 he published a Dutch translation of Romain Rolland's Jean Christophe (10 vols., with an introductory essay). In 1924 he received his doctoral degree, with the highest distinction, at the University of Leiden with the dissertation Dostoyevsky in the Eyes of Western Critics. In 1927 he left the communist party, but he remained interested in Marxism and in the political development of the Soviet Union and of Asia. After publishing a book on the history of the Eastern Roman Empire (Byzantium, 1928) he translated and edited the Harmsworth's Universal History of the World into Dutch, in co-operation with other historians (1929–1932, 9 vols.), with three added chapters written by himself. His first book publication in the field of Dutch history was a pioneering study on the history of Dutch historical writing during the Middle Ages (1932). His most famous books include a history of The Low Countries (1934) and a four-volume work with 36 short biographies of important Dutch (1938–1940), both in cooperation with his wife and fellow historian Annie Romein-Verschoor. In 1939, Romein was appointed professor of history at the University of Amsterdam. He survived World War II after being held hostage as a prisoner
