Maurits Baks was a son of Abraham Jozef Baks and Saarte Frank. He married Kaatje van Leeuwen in Naaldwijk on 26 August 1907, a daughter of Alexander van Leeuwen and Sara van Os. The couple had two children, namely Sara and Leentje. Both daughters have been killed in the Holocaust. Since 1922 Maurits' spouse Kaatje was an "inspector of the eccleciastical bath"(mikwah) as listed on her registration card of the Jewish Council. She and her husband were therefore "gesperrt because of function" (safeguarded from deportation - "bis auf weiteres" - until further notice).
Maurits Baks was born into a family with six children, of whom one son born in 1883 has died already in 1884, only 1 year old. His other siblings were Rosette born in 1875, he self born in 1877, Jozef born in 1881, Izaak born in 1885 and Mietje born in 1888. They have been all killed in the Shoah. His parents were married in Deventer on 8 April 1869 and they have died already before the war.
Maurits and Kaatje were brought into camp Westerbork on 9 May 1943, and from there two days later, on 11 May, deported to Sobibor. On 14 May 1943 upon arrival there they have been immediately killed.
