Given name: Ludwik Family name: Hirszfeld

In summer 1941 organized a course for doctors about infectious diseases. Doctor Kochman, who was German, obtained a permission for Hirszfeld and his family to stay in their villa in Saska Kepa. If he had not got involved in the RGO (Central Welfare Council) issue he would have been able to stay there. Just like many other Jews who converted to Christianity he issued a memorial by the agency of the RGO (Central Welfare Council) to doctor Frank. In the memorial he highlighted his sincere Catholic faith and asked for the right to live outside the ghetto. The RGO (Central Welfare Council) assured the professor that everything was on the right track. After having read the memorial the authorities sent the list of all people who signed it to the blue policemen and ordered them to bring these people to the ghetto as they were considered one hundred percent Jews. As a result Hirszfeld, his wife and daughter ended up in the ghetto. In summer 1941 they moved to the rectory in Grzybowski Square.

A professor, considered an anti-Semite.
