In 1929, Schuster was awarded the post of solo cellist in the Berlin Philharmonic Orchestra under Furtwängler, the youngest person ever to hold that position.
One of the many highlights of his New York Philharmonic career was on November 14, 1943, when he was scheduled to play Strauss's Don Quixote under Bruno Walter.
For the remainder of his career, Schuster traveled both nationally and internationally giving recitals and playing with the great conductors and orchestras of the world.
[1] Schuster made numerous recordings of concertos, sonatas and other chamber works with accomplished partners, such as his American Vox set of Beethoven's complete music for cello and piano with Friedrich Wührer; his first recording for that label, with the same pianist, featured the Richard Strauss and first Brahms cello sonatas.
Schuster was featured soloist under such conductors as Toscanini, Walter, Mitropoulos, Rodziński, Solti, Kubelík, Furtwängler, Bernstein, Jochum, Karajan, and Mehta.
