Johannes Prassek was a German Catholic priest born in Hamburg in 1911. After his ordination in Osnabrück in 1937, he served as a chaplain in Lübeck starting in 1939. During the Nazi era, he became an active member of the resistance by opposing National Socialist ideology through discussion groups and the distribution of anti-regime pamphlets. His efforts to support forced laborers, aided by his ability to speak Polish, eventually led to his arrest by the Gestapo in 1942.
