astroengine writes "When representatives from the Merseyside Maritime Museum paid a routine visit to Heathrow Airport, they were in for a surprise. Looking for any tidbits of the UK's immigration control history, they came across Einstein's Dover landing card dating back to 1933. Apart from being a wonderful snippet of physics history, having been handled by the legendary physicist who transformed the way in which we view the Universe with his general and special theories of relativity, the landing card is a stark reminder about the harrowing pre-war history of Nazi Germany. Stating his nationality as "Swiss," the landing card shows that Einstein, a Jew, had denounced his German nationality only weeks earlier in protest of Adolf Hitler's oppressive regime."
