The court found that he would however be allowed to use the name Sylou, which he claimed had been the surname of an early 19th-century ancestor who had emigrated to Norway.
[2] He studied in Norway under the supervision of Agathe Backer-Grøndahl, Catharinus Elling and Iver Holter, and also for several years abroad, in Berlin, Germany, and Vienna, Austria-Hungary.
In March 1940 he applied for a job in radio broadcasts from Germany to Norway, and he was hired as program presenter and news reader, based in Bremen.
Sylou-Creutz also lamented the absence of German-friendly Victor Mogens as a foreign news commentator in Norwegian radio.
[23] Via contacts in the German Reichskommissariat Norwegen (which was the highest authority over the Broadcasting Corporation), Sylou-Creutz also managed to see his music get a lot of airtime.
[27] By December 1941, reports of the internal quarrels involving Sylou-Creutz had reached the Norwegian-language American newspaper Nordisk Tidende, which described them as a "showdown between the Germans' errand boys".
[29] In 1940 Sylou-Creutz made announcements stating that Jewish music should be banned from Norwegian airwaves and all performers should also be members of Nasjonal Samling.
In 1941 this led to a conflict between the Church of Norway and the Nazi-led Norwegian Broadcasting Corporation, with increasing attempts at censorship from the Nazi authorities and boycotts from the priests.
The artists banned were Robert Riefling, Jan Wølner, Frithjof Backer-Grøndahl, Amalie Christie, Rolf Størseth and Kari Glaser.
The ban attracted great controversy, with the national music consultant Geirr Tveitt resigning in an 18-page protest letter to minister Gulbrand Lunde.
In comparison, non-Nazi artist Ivar Johnsen performed a single piece of Grieg's music in the park Fornøyelsesparken in Stavanger in storming rain with an audience of between 1,000 and 2,000 people the same day.
The Nazi-censured newspaper Larvik Dagblad stated at the time that it was to Sylou-Creutz's credit "both as a human being and an artist" to be able to perform "under these circumstances".
