Given name: Jan /Jonas Samuel/ Family name: Przedborski

Specialist in internal medicine, before the war, he was a doctor in the Municipal Health and Care Centre at Swietojerska Street No. 19, co-chairman of the Scientific Commission of the Physicians' Union of the Republic of Poland. In 1942, he managed a new orphanage, created at Zegarmistrzowska Street No. 14. On 7 August 1942, he couldn't get to the orphanage, because of a German blockade (from 7 to 9.30 a.m.). The children and the staff were then taken to the Umschlagplatz.

There were 1,000 children in the orphanage at that time, because during the action the children from the Main Shelter Home at Dzielna Street No. 39 and from the boarding school for religious children at Dzielna Street No. 8, were resettled there.
