Free Association of German Unions (FVDG), and paid staff

Submitted by syndicalist on January 23, 2018

I read in this interesting booklet

"Anarchists, Syndicalists, and the First World War"

(by Vadim V. Damier) that the Pre-WI German union, “Free Association of German Unions” (FVDG), had a paid staff of four. I gather at least one must've been the editor of the "Die Einigkeit" ("The Unity") and "Der Pionier" ("The Pioneer").........So I am wondering who the other paid staff positions may have been?

Anyone know?
