Ulrich Fleischhauer (14 July 1876 – 20 October 1960) (Pseudonyms Ulrich Bodung, and Israel Fryman) was a leading publisher of antisemitic books and news articles reporting on a perceived Judeo-Masonic conspiracy theory and "nefarious plots" by clandestine Jewish interests to dominate the world.
Fleischhauer was born in Thamsbrück, in Bad Langensalza, the son of a Lutheran deacon.
His career was at first grounded in the Imperial German Army where by 1918 Fleischhauer rose to the rank of Lieutenant-Colonel and regimental commander of a field artillery unit in Colmar. After suffering serious wounds, Fleischhauer retired from military service and received a government pension, although he continued to serve for some time as chairman of the National Federation of German Officers (Nationalverbandes Deutscher Offiziere).
After the army, Fleischhauer sought out something else to do full-time. The draw of the public policy arena attracted him. In the aftermath of the defeat of the German and Austria-Hungarian empires, a number of new political parties emerged, many arguing for pan-Germanism. Fleischhauer joined the German National People's Party (Deutschnationale Volkspartei, or DNVP) and was a representative of the far right wing. Intellectually, Fleischhauer was a disciple of Theodor Fritsch and through their common Völkisch movement circles he also developed friendships with a number of other revolutionary nationalists in secretive Aryan organizations such as the Thule Society. Fleischhauer was especially close to poet and political activist Dietrich Eckart, an early backer of Adolf Hitler.
