Question: How old was Arthur Fonjallaz when Amaudruz published Ubu Justicier au Premier Proces de Nuremberg? Passage:Initially a supporter of the Swiss fascist movement of Arthur Fonjallaz, he came to wider attention in 1949 when he published Ubu Justicier au Premier Proces de Nuremberg, one of the first works to question the veracity of the Holocaust. Increasingly active in neo-fascism, he organized conferences in Malmo in 1951 which led to the formation of a pan-European nationalist group known as the European Social Movement and then led the more radical splinter group known as the New European Order later that year. This group sought the creation of a new RomeBerlin axis to unite Europe against capitalism and communism and in January 1953 set up a European Liaison Office under Amaudruz in Lausanne to co-ordinate the work of affiliated groups. He also came an early member of the Volkspartei der Schweiz but left the party over the issue of South Tyrol (where he was opposed to irredentism). Of all the groups involved Amaudruz was closest to Ordine Nuovo. Conferences were held irregularly, although membership was fluid and Amaudruz devoted much of his time to writing for journals such as Nation Europa.
