Roman Polanski is a Polish and French film director, producer, writer, and actor. He won the Academy Award for Best Director for The Pianist (2002).
Roman was born in Paris, France, to parents from Poland, and was raised in Poland. His father, Ryszard Liebling (later Ryszard Polanski), was a Polish Jew, from Krakow. His mother, Bula Katz-Przedborska, who was evidently born in Warsaw, was raised Catholic, and was of partial Jewish ancestry (as well as possibly part Russian). Roman grew up as an agnostic. He and his family were placed in a concentration camp during World War II, from which he was able to escape. His mother was killed in the gas chambers. His father managed to survive.
Roman is married to French actress Emmanuelle Seigner, with whom he has two children, including actress and model Morgane Polanski. He was previously married to actress Sharon Tate, until her murder by the Manson family. Sharon was pregnant with her and Roman’s son at the time.
Roman’s paternal grandfather was Samson Hirsch Liebling (the son of Dawid Liebling and Golda).
Roman’s paternal grandmother was Maria Imerglück (the daughter of Hirsch Imerglück and Reizla). Maria was born in Niegoszowice.
