Juda Crost was a son of Levie Crost and Catharina Sluijters. He married Sara Scheffer on 8 March 1933 in Amsterdam, a daughter of Willem Scheffer and Vrouwtje Lopes Dias. The couple had four children: Catharina, Willem, Levie and Jakob. All the four children have been killed in Auschwitz, together with their mother Sara Schffer, on 8 October 1942.
Juda Crost was sent on 23 March 1942 to the forced labor camp Gijselte in the province of Drenthe. On 2 and 3 October the Jewish labor camps were evacuated but many labor camps for different purposes remained in use. Thousands of men were taken to Camp Westerbork. At the same time, their families were arrested and - under the heading of family reunion - brought to Camp Westerbork. Those days, more than 17.000 people stayed in that camp at the heath of Drenthe. The days and weeks that followed, nearly all thes people were deported to Auschwitz. Juda Crost arrived on 3 October 1942 in Camp Westerbork and was deported to "the East" on 8 October 1942. Eventually he lost his life in Mauthausen on 22 April 1945.
