The Germans occupied Denmark in April 1940, but the Danish government remained in existence and was able to protect Danish Jews. In August 1943, the government resigned after refusing to accede to German demands. German police began to arrest Jews in early October. Leif and his family decided to flee, and were smuggled by fishing boat to safety in Sweden. In Sweden, Leif attended school and his parents worked in a garment factory. The family returned to Denmark after the end of the war.
