Throughout the 1920s Chanler corresponded frequently with his old friend Ludwig von Höhnel, then living in retirement in Vienna, on the "Jewish world conspiracy" and the degree to which von Höhnel shared Chanler's antisemitic ideology, writing on March 22, 1923: "You don't seem disturbed by the fact that your town is overrun by Jews." Chanler accepted as authentic the widely recognized forgery, The Protocols of the Elders of Zion, and he employed agents to compile dossiers on Jewish public figures in the US and other countries.
