Leopold Socha was a Polish sewer worker during World War II, known for his courageous actions in saving Jewish lives. He lived in the city of Lwów, which is now part of Lviv, Ukraine. When the Nazi regime began persecuting Jews, Socha used his knowledge of the city's sewer system to help hide a group of Jewish people from the authorities. Socha's efforts included providing food and shelter to those he rescued, risking his own life in the process. His story is a testament to human bravery and compassion during one of history's darkest periods, highlighting the importance of standing against injustice.
