 In July 1939, a dramatization of the novel was arranged in Paris in honour of Roth (who had died in May 1939) and Zeisl, who had recently arrived in Paris in flight from Nazi Germany, wrote some incidental music for this production.
 This inspired him to create a complete opera based on Roth's work, for which he persuaded his friend Hans Kafka (1902—1974) to write a libretto.
 Zeisl composed the first act by 1940, by which time he was now living in New York.
 Kafka was not able to produce the libretto for Act II until 1957.
