Wim Tunderman was born on 14 January 1903, in the city of Rotterdam. On 26 December 1942, he died as a result of medical experiments in the Dachau camp. He was married to Bastiaantje (Jeanne) Kurpershoek. Jeanne learned of his passing on 8 January 1943. Unable to cope with his death, she died three months later. At an early age, Wim felt the calling to become a minister. Not an easy path since his circumstances were not ideal and also his father did not see a future for Wim as a minister. But he made it and started as an assistant minister in the village of Vrouwenpolder in the Dutch province of Zeeland in 1933. In 1938 Reverend Tunderman accepted a calling in the city of Groningen. During his calling he stood firmly and publicly against national socialism. He continued doing this after the occupation by the Germans in 1940. He met his nemesis and was arrested on 9 January 1942, by the German SD. After spending some time in the camp in Amersfoort, he was put on a transport to Dachau in October 1942. Together with a number of other, mainly Polish, clerics, he was subjected to medical experiments such as injecting pus into his legs. This was too much for Wim and on 26 December 1942, he died as a result of this horrible experiment. Wim had prepared for this and knew he would die in the belief his death was a sacrifice in the service of life after the resurrection in Christ.
