Viktor Ullmann (1 January 1898 – 18 October 1944) was a Silesia-born Austrian[1] composer, conductor and pianist.


Viktor Ullmann was born on 1 January 1898 in Cieszyn (Teschen), which belonged then to Austrian Silesia in the Austro-Hungarian Empire. Both his parents were from families of Jewish descent, but had converted to Catholicism[2] before Viktor's birth. As an assimilated Jew, his father, Maximilian, was able to pursue a career as a professional officer in the army of the Austro-Hungarian Empire. In World War I he was promoted to colonel and ennobled.

One writer has described Ullmann's milieu in these terms: "Like such other assimilated German-speaking Czech Jews as Kafka and Mahler, Ullmann lived a life of multiple estrangements, cut off from Czech nationalism, German anti-Semitism and Jewish orthodoxy".[3]

Beginning in 1909 Viktor attended a grammar school (Gymnasium) in Vienna. His musical talents and inclinations soon gave him access to Arnold Schönberg and his circle of pupils. Upon finishing school, he volunteered for military service.

After deployment on the Italian Front at Isonzo, he was granted study leave, which he used to start studying law at Vienna University. There he also attended the lectures of Wilhelm Jerusalem. At the beginning of 1918 he was accepted in Schöenberg's composition seminar. With Schöenberg he studied the theory of form, counterpoint and orchestration. Ullmann was an excellent pianist, although he had no ambitions for a career as a soloist.

In May 1919, he broke off both courses of study and left Vienna in order to devote himself fully to music in Prague. His mentor was now Alexander von Zemlinsky, under whose direction he served as a conductor at the New German Theatre of Prague (now the Prague State Opera) until 1927. In the following season, 1927–28, he was appointed head of the opera company in Aussig an der Elbe (Ústí nad Labem), but his repertoire, including operas by Richard Strauss, Krenek and others, was too advanced for local tastes, and his appointment was terminated.

In 1923 with the Sieben Lieder mit Klavier (7 Songs with Piano) he witnessed a series of successful performances of his works, which lasted until the beginning of the 1930s (Sieben Serenaden). At the Geneva music festival of the International Society for New Music in 1929, his Schönberg Variations, a piano cycle on a theme by his teacher in Vienna, caused something of a stir. Five years later, for the orchestral arrangement of this work, he was awarded the Hertzka Prize, named in honor of the former director of Universal Edition. In the meantime he had been appointed conductor in Zürich for two years. As a result of his interest in anthroposophy, a movement founded by Rudolf Steiner, he spent another two years as a bookseller in Stuttgart, but was forced to flee Germany in mid-1933 and returned to Prague as a music teacher and journalist.

During this period he worked with the department of music at Czechoslovak Radio, wrote book and music reviews for various magazines, wrote as a critic for the Bohemia newspaper, lectured to educational groups, gave private lessons, and was actively involved in the program of the Czechoslovak Society for Music Education. At about this time Ullmann made friends with the composer Alois Hába, whom he had known for some time. Ullmann enrolled in Hába's department of quarter tone music at the Prague Conservatory, where he studied from 1935 to 1937.

While his works of the 1920s still clearly show the influence of Schönberg's atonal period, especially the Chamber Symphony Op. 9, the George Songs Op. 15 and Pierrot Lunaire, Op. 21, Ullmann's compositions from 1935 onwards, like the String Quartet No. 2 and Piano Sonata No. 1, are distinguished by a musical development that is more independent of Schönberg's inspiration. Similarly the opera Fall of the Antichrist develops the issues raised by Alban Berg's opera Wozzeck. Dissonant harmonics, highly charged musical expression, and masterly control of formal structure are characteristic of Ullmann's new and henceforth unmistakable personal style.

Theresienstadt concentration camp[edit]

On 8 September 1942 he was deported to the Theresienstadt concentration camp. Up to his deportation his list of works had reached 41 opus numbers and contained an additional three piano sonatas, song cycles on texts by various poets, operas, and the piano concerto Op. 25, which he finished in December 1939, nine months after the entry of German troops into Prague. Most of these works are missing. The manuscripts presumably disappeared during the occupation. Thirteen printed items, which Ullmann published privately and entrusted to a friend for safekeeping, have survived.

The particular nature of the camp at Theresienstadt enabled Ullmann to remain active musically: he was a piano accompanist, organized concerts ("Collegium musicum", "Studio for New Music"), wrote critiques of musical events, and composed,[4] as part of a cultural circle including Karel Ančerl, Rafael Schachter, Gideon Klein, Hans Krása, and other prominent musicians imprisoned there. He wrote: "By no means did we sit weeping on the banks of the waters of Babylon. Our endeavor with respect to arts was commensurate with our will to live."[3]

Overall, Ullmann "probably made the most significant contribution of any single individual to the musical life of Terezin", composing 20 works in the camp.[5]

On 16 October 1944 he was deported to the camp at Auschwitz-Birkenau, where he was killed in the gas chambers two days later.

Later works[edit]

The work he completed in Theresienstadt was mostly preserved and comprises, in addition to choral works, song cycles and a quantity of stage music, such significant works as the last three piano sonatas, the Third String Quartet, the melodrama based on Rilke's Cornet poem, and the chamber opera The Emperor of Atlantis, or The Disobedience of Death, with a libretto by Peter Kien. Its premiere was planned for Theresienstadt in the autumn of 1944, conducted by Rafael Schachter, but it is believed that the SS commander noticed similarities between the Emperor of Atlantis and Adolf Hitler and suppressed it. However, eye-witness Herbert Thomas Mandl argues, "that the Emperor is not Hitler".[6] The opera was first performed in Amsterdam in 1975 in a version of the conductor Kerry Woodward. It has been broadcast by BBC television in Britain, and there have been productions in several countries. Important productions took place in Bremen and Stuttgart in 1990; American premieres took place in San Francisco in 1975 and in Brooklyn in 1977. Other works include the song-cycle "Man and his Day" to poems by Ullmann's friend, the poet and later historian of Theresienstadt, H. G. Adler.

Since 1993 it is possible to perform the original version of the opera with the help of Karel Berman, based on his Terezin rolebook and the musicologist Ingo Schultz. This reconstructed original version of the original score has been used for the production of the opera done by the director Herbert Gantschacher for ARBOS - Company for Music and Theatre. This production used also Ullmann's original title "The Emperor of Atlantis or The Disobedience of Death" and has been recorded by the Prague label STUDIO MATOUS in 1994/1995. This production of the opera by Herbert Gantschacher has been performed for the first time at Terezin on 23 May 1995.[7] From these first performances at Terezin ever a live recording exists done by ARBOS – Company for Music and Theatre.[8] In all, Ullmann worked on the opera for 27 years, from the first impressions in the First World War in 1917 to the finalization at Terezin in 1944.[9]

The most concrete formulation of this discourse occurs in the Emperor of Atlantis, with the parable of the Emperor's game with Death for Life. The "game", which concerns the Emperor's plan for the total destruction of all human life, ends with the ruin of the Emperor and with the vision of a new understanding between life and death.

When Ullmann was deported to Auschwitz, he left his works in the safekeeping of the philosopher Emil Utitz. After the war, Utitz gave them to H. G. Adler in Theresienstadt in 1945, and Adler brought the scores to England in 1947. Adler subsequently placed them on long-term loan with the Allgemeine Anthroposophische Gesellschaft in Dornach (AAG), Switzerland. In an apparent breach of contract the AAG subsequently deposited them with the Paul Sacher Stiftung, Basle, where they are currently being held illegally, prior to the preparation of a legally valid loan agreement.[10]

List of the Prague and Theresienstadt works[edit]

In the middle of 1942, shortly before his deportation to Theresienstadt concentration camp, Ullmann drew up a comprehensive list of his compositions to that point. This list was preserved in a London library as part of a letter to a correspondent whom it has not hitherto been possible to identify. In contrast to earlier lists of works, the London list is distinguished by an unbroken sequence of opus numbers (1–41) and the unmistakable incorporation of works or titles already known. Ullmann's list of works is of incalculable value in light of the lost or missing compositions, although it makes clear the full extent of the loss caused by persecution and war.

In the following summary Ullmann's opus numbering has been used, and extended for the opus numbers given to works composed in Theresienstadt. The order of titles is essentially chronological and takes account both of compositions known from earlier lists of works as well as of those bibliographically recorded. Uncertain dating is indicated by (?). Traces of an earlier numeration derive from the list of works from the 1920s (Riemann Musiklexikon 11/1929). These references occur only in connection with the "Schönberg Variations", which in relation to the opus numeration and to the chronology cut across the principle of arrangement used.
