Despite being unable to neither read nor write music , he whistled melodies which were then transcribed and performed in the outdoor kiosks of Vienna . After being taken prisoner by the Germans in 1942 , the Nazis burned all his possessions including his house , his documents and his scores . He was killed in the concentration camp of Theresienstadt at the age of ninety , on September 20 , 1942 . Miraculously , thanks to a cousin , who had fled with his family to England before the Kristallnacht , there survived two scores of his unpublished musical waltz ( " Aeroplane waltz " and " Diana waltz " ) . The writer Elisa Springer , his maternal granddaughter , who wrote a book , '' Das Schweigen der Lebenden '' ( '' The Silence of the Living '' ) , preserved these scores
