Jan Pietraszko was a Polish Catholic bishop who served as an auxiliary for the Kraków archdiocese and held the title of Titular Bishop of Turrisblanda. Born in 1911, he was ordained a priest in 1936 and later became a close collaborator of Archbishop Adam Stefan Sapieha. He was highly regarded for his spiritual guidance, his work as a confessor, and his influential sermons. During the communist era, he faced surveillance by secret services due to his efforts to preserve religious art and advocate for the construction of new churches.
