[3] Within the Hamburg party a power base had been built up by Heinrich Laufenberg with Rudolf Lindau, Wilhelm Düwell and Paul Frölich amongst his closest lieutenants.

[10] Along with Laufenberg and Jan Appel, Wolffheim attended the Heidelberg conference that saw the birth of the Communist Workers Party of Germany (KAPD) and was a founder member of this group.

[12] Individually Wolffheim was close to the rightist General Paul Emil von Lettow-Vorbeck whilst along with Laufenberg he had met with Ernst Graf zu Reventlow immediately prior to the Kapp Putsch.

[13] Following his expulsion from the KAPD Wolffheim became a member of the League for the Study of German Communism, a pro-nationalist group that included representatives of business and army officers amongst its membership.

[14] However his involvement with Nazism was never more than perfunctory (probably due to his Jewishness) and he instead became associated with the Gruppe Sozialrevolutionärer Nationalisten, a national revolutionary group founded by the journalist Karl Otto Paetel in 1930.
