married Elisabeth "Elsa" Kunwald (also a pianist), who bore him a son, Hans, in 1902. Hans was to be the father of the German politician Klaus von Dohnányi and of the conductor Christoph von Dohnányi, long Music Director of the Cleveland Orchestra. Hans distinguished himself as a leader of the anti-Nazi resistance in Germany and was ultimately executed in the final stages of World War II. In addition to Hans, Dohnányi and Elsa Kunwald also had a daughter, Greta. Following an invitation by the violinist Joseph Joachim, a close friend of Brahms, Dohnányi taught at the Hochschule in Berlin from 1905 to 1915. There he wrote The Veil of Pierrette, Op. 18, and the Suite in F-sharp minor, Op. 19. Returning to Budapest, he appeared in a remarkable number of performances over the following decade, notably in the Beethoven sesquicentenial year of 1920/1921. Before World War I broke out, Dohnányi met and fell in love with a German actress (also described as a singer), Elsa Galafrés, who was married to the Polish Jewish violinist Bronisław Huberman. They could not yet marry as their spouses refused to divorce them, but nonetheless, Dohnányi and Elsa Galafrés had a son, Matthew, in January 1917. Both later gained the divorces they sought and were married in June 1919. Dohnányi also adopted Johannes, Elsa's son by Huberman. During the short-lived Hungarian Soviet Republic of 1919, Dohnányi was appointed Director of the Budapest Academy, but a few months later the new interim government replaced him with the prominent violinist Jenő Hubay after Dohnányi had refused to dismiss the pedagogue and composer Zoltán Kodály from the Academy for his supposedly leftist political position. However in 1920, with Admiral Horthy becoming Regent of Hungary, Dohnányi was named Music Director of the Budapest Philharmonic Orchestra and as such promoted the music of Béla Bartók, Zoltán Kodály, Leo Weiner and other contemporary Hungarian composers. That same 1920 season, he performed the complete piano works of Beethoven and recorded several of his works on the Ampico player-piano-roll apparatus. He gained renown as a teacher. His pupils included Andor Földes, Mischa Levitzki, Ervin Nyiregyházi, Géza Anda, Annie Fischer, Hope Squire, Helen Camille Stanley, Bertha Tideman-Wijers, Edward Kilenyi, Bálint Vázsonyi, Sir Georg Solti, Istvan Kantor, Georges Cziffra and Ľudovít Rajter (conductor and Dohnányi's godson). In 1933 he organized the first International Franz Liszt Piano Competition. In 1937 Dohnányi met Ilona Zachár, who was
