Hermann Cohen was a 19th-century German-Jewish pianist and musician who later became a Discalced Carmelite priest. Born in Hamburg in 1820, he studied music under Franz Liszt before converting to Roman Catholicism. After entering the Carmelite order, he dedicated his life to religious service, eventually playing a significant role in restoring the order's presence in both England and France. He died in Spandau in 1871, leaving behind a legacy of musical talent and religious devotion.
