Daniel Snowman is Senior Research Fellow at the Institute of Historical Research, University of London, UK. Educated at Cambridge and Cornell, he was a Lecturer at Sussex University and went on to work for the BBC as Chief Producer, Features (Radio). His books have tended to cross conventional historiographical boundaries, from Kissing Cousins (1977), a comparative study of British and American social attitudes and values, to The Hitler Emigrés (2002), which examined the cultural impact of refugees from Nazism. The Gilded Stage: A Social History of Opera (2009) was a pioneering attempt to place the history of opera in its widest historical perspective.
