Philip Slier
Philip "Flip" Slier (4 December 1923 – 9 April 1943) was a Dutch typesetter of Jewish origin who lived in Amsterdam during the German occupation of the Netherlands in World War II. At the age of 18, he received a letter from the Jewish Council of Amsterdam—under orders from the German occupiers—that he was to report to Camp Molengoot or face arrest. He wrote 86 letters from 25 April to 14 September 1942 detailing his experiences as a forced labourer at the labour camp.
