Duifje van der Molen was a daughter of Meijer van der Molen and Esther Appel. She married 24 April 1919 in Amsterdam the cigar maker Wolf Hartlooper, a son of Joseph Hartlooper and Sara Bonte. The couple had one son, Joseph, who was born in Amsterdam in 1926.
When Wolf Hartlooper was still unmarried, he worked in Antwerp as a cigar maker. After his marriage in 1919, he became a café holder; he owned café De Molen at Gelderschekade 120 and he lived with his wife Duifje in the beginning with his father-in-law Joseph Bonte at Rapenburgerstraat 81. Afterwards they lived since 1926 at Nieuwmarkt 15 II where also Isaäc Liefman and his wife Naatje van der Molen lived, and later they resided at nr. 15 parterre, where also Wolf’s father Joseph Hartlooper and his daughter Roosje lived.
Wolf Hartlooper and his family were “exempted until further notice” based on owing a business, a café. After the request for a Sperre was granted because of the business, a sign with the text “Joodsch Lokaal” (Jewish Place ) was placed on the façade. In fact, the Joodsch Lokaal Sperre which was linked to the licence to operate a Jewish business (shop-store etc), was a special Jewish Council Sperre.
Wolf Hartlooper was not entirely healthy; he suffered from a heart disease.His son Joseph, who had a 3-year education of U.L.O. and a type diploma, cooperated in the café as servant ( waiter), in a licenced Jewish Place (Joodsch Lokaal). But eventually, the Hartlooper family was arrested and taken to Westerbork during the big raids in Amsterdam in the end of May 1943. They all arrived in Westerborkf and stayed for a few days in barrack 64. On 1 June they were deported to Sobibor and on arrival there on 4 June 1943, Wolf Hartlooper, his wife Duifje Hartlooper-van der Molen and their son Joseph have been immediately killed.
