In 1935, possessing extensive international experience in conducting after leading the Berlin Philharmonic, the Hamburg Philharmonic and the Washington National Symphony, among others, he decided to settle in the United States, where he became a teacher and guest conductor of the USA main orchestras. During this period, Walter also dedicated himself to the musical composition.
