The Katzenberger Trial was a notorious Nazi show trial. A Jewish businessman and leading member of the Nuremberg Jewish community, Lehmann (Leo) Katzenberger, was accused of having an affair with a young "Aryan" woman, and on 14 March 1942 was sentenced to death. The trial's presiding judge, Oswald Rothaug, was later tried at the Nuremberg trials (see Judges' Trial) and sentenced to life imprisonment. The Katzenberger Trial later provided a subplot in the 1961 film Judgment at Nuremberg. Background Leo Katzenberger (born 28 November 1873 in Maßbach, near Bad Kissingen) and his two brothers owned a large wholesale shoe shop, as well as 30 shoe shops throughout southern Germany. Katzenberger was a leading member of the Nuremberg Jewish community, and from 1939 was chairman of the Nuremberg Jewish Cultural Organization. He had a long-standing friendship with a young photographer, Irene Seiler (née Scheffler, born 26 April 1910 in Guben), who rented rooms in an apartment house the Katzenbergers owned that was next to the firm's offices. For years, local gossips had claimed that Seiler and Katzenberger were having an affair. Both were married. Trial An unknown person denounced Katzenberger to the authorities, and he was arrested on 18 March 1941 under the so-called Rassenschutzgesetz ("Racial Protection Law"), one of the Nuremberg Laws, which made it a criminal offence, Rassenschande ("racial defilement"), for Aryans to have sexual relations with Jews. Katzenberger consistently denied the charges, as did Seiler, who claimed their relationship was like that of a father and daughter. The investigating judge initially concluded there was too little evidence to proceed with the case, but the investigation attracted the attention of Oswald Rothaug, a judge known for his severity and fervent support for Nazism. Recognising the publicity such a trial would generate and seeing it as a way to display his Nazi credentials and further his career, Rothaug arranged for the case to be brought to him. He sent tickets for the trial to all the prominent Nazis in Nuremberg. No conclusive evidence was presented during the trial that Katzenberger and Seiler had ever had an affair (Seiler had been Katzenberger's tenant since 1932), let alone that it had continued during the war. The law at the time did not call for the death sentence for breaking the Rassenschutzgesetz; the normal sentence would have been several years' imprisonment. Despite this, however, the Volkschädlingsgesetz, a wartime law, allowed capital punishment if
