critic of British protectionism. The Nazi police authorities classified Liepmann as an enemy of the state after his emigration. In early 1940 the Reich Security Main Office added him to The Black Book, an index of persons who, in the event of a successful invasion of Britain by the German army, were to be found and arrested as a matter of high priority by SS Commandos who would follow the occupying forces. In early 1940 Liepmann was offered research funding at Queen's University in Kingston, Ontario, but was unable to take it up owing to his internment by the British authorities in May 1940 as an enemy alien. Following his release in February 1941, he was unable to obtain either a visa or an ocean passage to Canada to take up the position. In 1942 he received a scholarship to work at the Royal Institute of International Affairs/Chatham House in Cambridge; then from April to September 1943 he was employed for his linguistic skills as a monitor by the BBC. From January 1944 Liepmann was a German teacher at the County Grammar School for Boys (now Langley Park School for Boys) in Beckenham, Kent.
