Founded in 1924, the Ostrowtzer Hilfs Farein was named after the town of Ostrowiec in Poland. The society’s mission was to provide support to Ostrovtzers who had immigrated to Toronto, offering small loans, medical assistance, and a fostering a sense of community. In the aftermath of the Holocaust, the society extended its relief efforts to surviving Ostrovtzers around the globe and became known as the United Ostrowtzer Hilfs Committee. This collection comprises over three hundred letters sent to Max Hartstone in his role as secretary of the committee. These letters document the efforts of the United Ostrowtzer Hilfs Committee, in collaboration with Ostrovtzer societies worldwide, to aid and support to Holocaust survivors from Ostrowiec. They also offer insight into the immediate, postwar experiences of Holocaust survivors. The letters have been digitized and can be found here.
