[2] Krogmann was a founder member of the Freundeskreis der Wirtschaft, an influential group of far right industrialists established in 1932 by Wilhelm Keppler.
[5] His appointment was ratified in no small degree because of his status as a member of one of Hamburg's pre-eminent mercantile families and as such it was hoped that he would appeal to the business community in the city, much of which was sceptical about the Nazis.
However, as Kaufmann's power grew so Krogmann's status diminished so as by 1937 he had been demoted to the lesser title of First Councillor of the Municipal Authority.
[7] Despite his shaky status, Krogmann, a devotee of the writings of Richard Wagner, Paul de Lagarde and Houston Stewart Chamberlain, was a staunch believer in Nazism, especially its antisemitic aspects, and rigorously enforced anti-Jewish laws within Hamburg whilst publicly speaking in support of them elsewhere.
[4] He demonstrated this in particular in a speech he delivered to the Ostasiatischer Verein in 1935 in which he rounded on members of the business community who were critical of the racial policy of the Third Reich, whilst emphasising the "decisive importance" of the Jewish question.
