Sigurd Larsen grew in Berlin, son of a Danish father and German mother. He participated as a German soldier in the First World War in which he was severely injured. As a result of that, his parents asked the German nationality to avoid his being recruited again.
Joachim Marcuse (born in 1917) who was persecuted because he was a Jew finished in the mid thirties his professional formation in the wood trade when he met Sigurd Larsen. He knew that Larsen helped business friends to emigrate during that times. During the war, Marcuse was forced to hard labor in a wood factory. One day it occurred to him to ask Larsen to rescue him, his wife Gerda and his friend Kurt Levin, hid in a wood freight of Germany. After having thoroughly studied the plan, Larsen committed himself to help him in the escape. Nevertheless, he suggested not going to Denmark as a destination, because the German troops had already occupied it. As an alternative he organized an exportation of wood to Sweden. Within the wagons he organized a hideout for three people. On December 24th, 1942 Larsen closed the wagon in which the three young people were hidden. During four long days the wagon stayed at the Berlin train station until finally it set off to Sweden. During old night of the year 1942 Joachim and Gerda Marcuse together with Kurt Levin, a close friend of the couple, whom, they had included in their escape plans, arrived Sweden, were they were recognized as political refugees.
For fear that his illegal support was discovered, Larsen took his wood commerce to Denmark short after the successful escape of his friends took place and went to live with his family in Copenhagen.
