Lothar Wallerstein

Lothar Wallerstein was a musician, conductor, and theatre director of Austrian descent, born in what is now the Czech Republic. His career in music and theatre spanned several prominent institutions, including the Vienna State Opera, Salzburg Festival, and Metropolitan Opera, where he worked as a stage manager. In 1926, he took on the role of stage director at the Vienna State Opera, a position that allowed him to collaborate with notable composers, such as Richard Strauss, with whom he reworked Mozart's Idomeneo in 1931.

Wallerstein's life took a significant turn in 1940 when he emigrated to New York City to escape the growing Nazi influence in Austria and the subsequent invasion of the Netherlands, where he had initially sought refuge. He became a U.S. citizen in 1945. Following World War II, Wallerstein returned to Europe, where he dedicated himself to teaching and education. He founded an opera school in The Hague, Netherlands, and taught acting classes to singers, leaving a lasting impact on the world of opera and music. Wallerstein passed away in 1949, four years after gaining American citizenship.
