musicum", "Studio for New Music"), wrote critiques of musical events, and composed, 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." Overall, Ullmann "probably made the most significant contribution of any single individual to the musical life of Terezin", composing 20 works in the camp. On 16 October 1944 he was deported to the camp at Auschwitz-Birkenau, where on 18 October 1944 he was killed in the gas chambers. Later works 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". 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.
