Wiesenthal and his brother attended high school at the Humanistic Gymnasium in Buchach, where classes were taught in Polish. There Simon met his future wife, Cyla Müller, whom he would marry in 1936. Hillel fell and broke his back in 1923 and died the following year. Rosa remarried in 1926 and moved to Dolyna with her new husband, Isack Halperin, who owned a tile factory there. Wiesenthal remained in Buczacz, living with the Müller family, until he graduated from high school—on his second attempt—in 1928.
