In the spring of 1938, Lise Meitner, being a Jew, had to leave Berlin and went to a job offered her by Manne Siegbahn in the Nobel Institute of Stockholm. Being Austrian, she had not up until then been seriously affected by Hitler’s persecution of Jews; however, in the spring of 1938, Austria was annexed by Hitler and she had to get out of the country. Dutch colleagues smuggled her into Holland without a visa and thence to Sweden. The German team would have to carry on without her.
