Rudolf Kolisch

He put Kolisch to work in the "Society for Private Musical Performances in Vienna" (Verein für musikalische Privataufführungen in Wien).

Numerous works were written for this ensemble by composers including Alban Berg, Anton Webern, Schoenberg, and Béla Bartók.

He became a member of the faculty at the Internationale Ferienkurse für Neue Musik in Darmstadt, Germany, along with his close friends and long-time associates Eduard Steuermann and Theodor Adorno.

At that time he was invited by Gunther Schuller to become head of the Chamber Music department at the New England Conservatory in Boston.

During the summers of 1974 through 1977, he also taught chamber music performance at the annual Schoenberg Seminars in Mödling, Austria near Vienna.
