Catharina Wagenhuis was the youngest of the three daughters of Isaäc Wagenhuis and Maria Augurk. She was born on 25 March 1924 in Amsterdam and she was a seamstress by profession. She was unmarried and lived at home with her parents in the Bethaniëndwarsstraat 15 2nd floor and up from August 1941 in the Jodenbreestraat 2 1st floor in Amsterdam. Catharina had two sisters: Sara, who was born on 30 May 1914 and who got married in 1936 to Samson de Vries and lived since then with her own family elsewhere in the city, and her eldest sister Rosa, who was born on 26 November 1912.
On 26 May 1943, when the Germans organized large-scaled raids in Amsterdam, about 3000 Jews were arrested, among them also Catharina Wagenhuis. Through the assembly area Polderweg they were carried off to the Muiderpoort station and from there per train to Westerbork. There, Catharina ended up in barrack 57 but already on 1 June 1943, with another 3005 deportees, she was put on transport to Sobibor. Upon arrival there on 4 June 1943 the 19-year old Catharina Wagenhuis and the many other deportees were immediately gassed in the gas chambers there. The only survivor of that transport was Jules Schelvis.
