‘This contract is certainly my greatest success as a composer, so far’, commented Bartók in 1918 on contracting with the Viennese publisher Universal Edition. After years of hit-and-miss publishing with two Budapest firms, Rozsnyai and Rózsavölgyi, Bartók was proud at having caught, with the 1917 Budapest première of his ballet The Wooden Prince, the attention of Universal Edition's director, Emil Hertzka. Hertzka was renowned for his cultivation of such musical talents of central Europe as Mahler, Schoenberg, Janáœk, Berg and Szymanowski. Until about 1926, when Hertzka developed heart troubles and took a lesser role in managing the firm, Bartók was generally happy with his Viennese publishing connexion. Universal Edition had quickly moved to bring out the considerable backlog of his compositions, had strongly promoted his works through its new house journal Muskiblätter des Anbruch, and had often spurred his imagination with complimentary scores, suggestions and in-house gossip. But then, from 1926 to 1932, when Hertzka died, Bartók's dealings with Universal Edition became progressively less personal, less prompt and sometimes even chilly, although his compositions did continue to appear regularly from the publisher and to receive a quite reasonable level of exposure. Thereafter, as the Depression and financial difficulties led to more serious publication delays and breakdowns in communication, Bartók grew bitter and imperious. Several times after 1932 he threatened to terminate his contract with Universal Edition.
