They had three children: Nuria Dorothea (born 1932), Ronald Rudolf (born 1937), and Lawrence Adam (born 1941). Gertrude Kolisch Schoenberg wrote the libretto for Schoenberg's one-act opera Von heute auf morgen under the pseudonym Max Blonda. At her request Schoenberg's (ultimately unfinished) piece, Die Jakobsleiter was prepared for performance by Schoenberg's student Winfried Zillig.
