Career
Immediately after the bombing of Rotterdam during the German invasion in 1940, he set up the first Dutch resistance group, De Geuzen, and published the Geuzenbericht, a resistance pamphlet, the very next day. After a show trial, he was shot at Scheveningen on 13 March 1941 together with 17 others, including three Communists involved in the February Strike. He was posthumously awarded the Resistance Cross which his widow received in 1955.
