Josef Waldmann (known as Jossel) fled to the Netherlands on 22 January 1939. He was taken in at various assembly points for Palestine Pioneers. From 12 January 1940 until 7 December 1942 he lived as a ward at the youth aliyah home in Loosdrecht, the Paviljoen Loosdrechtse Rade. Afterwards he went into hiding. He left his hiding place to try to escape to Switzerland together with seven other Palestine Pioneers (Siegbert Leo Adler, Bernard Aschheim, Robert Jozef Dürheim, Juda Pinkhof, Fabian Schön, Lilli Kellner and Esra Jurovics). They were caught at the Belgian border.
