Marek Ferdynand Arczyński

Ferdynand Marek Arczyński, cryptonym "Marek" or "Lukowski", was one of the founding members of an underground organization Żegota in German-occupied Poland, from 1942 to 1945. Żegota's express purpose was to help the country's Jews survive the Holocaust; find places of safety for them, and provide relief payments to thousands of families. Poland was the only country in occupied Europe with such an organization during World War II.
