Maximilian Schell was a Swiss film and stage actor, who also wrote, directed and produced some of his own films. He won the Academy Award for Best Actor for the 1961 American film Judgment at Nuremberg, his second acting role in Hollywood. Born in Austria, his parents were involved in the arts and he grew up surrounded by acting and literature. While he was a child, his family fled to Switzerland in 1938 when Austria was annexed by Nazi Germany, and they settled in Zurich. After World War II ended, Schell took up acting or directing full-time. He appeared in numerous German films, often anti-war, before moving on to Hollywood. Schell was top billed in a number of Nazi-era themed films, as he could speak both English and German. Among those were two films for which he received Oscar nominations: The Man in the Glass Booth, where he played a character with two identities, and Julia, where he helps the underground in Nazi Germany. His range of acting went beyond German characters, however, and during his career, he also played personalities as diverse as Venezuelan leader Simón Bolívar, Russian emperor Peter the Great, and scientist Albert Einstein. For his role as Vladimir Lenin in the television film, Stalin, he won the Golden Globe Award. On stage, Schell acted in a number of plays, and his was considered "one of the greatest Hamlets ever." In Schell's private life, he was an accomplished pianist and conductor, performing with Claudio Abbado and Leonard Bernstein, and with orchestras in Berlin and Vienna. His elder sister, Maria Schell, was also a noted Hollywood actress, about whom he produced the documentary, My Sister Maria, in 2002.
