Moses Ben Israel Isserles (1525-1572), one of the great authorities on Jewish law in Poland. He founded a religious academy in Krakow. His rationalist theology, his interest in Greek philosophy, in sciences and secular knowledge make him one of the forerunners of Jewish enlightenment. In one of his legal responses, he wrote: "Better to live on dry bread and peace in Poland," than to live in greater prosperity in countries more dangerous for Jews. Until World War II, his grave in Krakow was the venue of an annual pilgrimage for Polish Jews.
