Oskar came from a family of a Kolín businessman Adolf Arnstein and his wife Kamila Arnsteinová who was originally from Votice. He was born on 5 June 1896 at Karlovo náměstí 90 where his father’s firm, trading with assorted goods and alcohol, resided. He met his wife Anna Strasserová (* 13 September 1908) in Chrudim. They got married in 1932 and after five years of marriage their son Pavel was born (* 21 June 1937). On 26 October 1941, that is, two years after the Protectorate was established, they were all taken from Prague by the C transport to Lodź, Poland. Oskar died here on 3 November, just a few days after their arrival. His wife and son had survived in the ghetto for another half a year. Both their death certificates state the day of death on 26 April 1942. Pavel thus did not live to see his fifth birthday.
