Frederick Valk (10 June 1895 – 23 July 1956) was a German-born stage and screen actor of Czech Jewish descent who fled to the United Kingdom in the late 1930s to escape Nazi persecution, and subsequently became a naturalised British citizen. Despite making his later career in the English-speaking world, Valk never attempted to shed his heavy accent in either his stage or film work, and it became a trademark, particularly in film where he was often the first choice for a role which called for a German or generic Central European accent.
