Greetings. Has anyone ever identified who the "A. Markoff" was, who wrote in The Party Organizer, often in a column called "Agit-Prop Work" and often with a title like "director of Agitation and Propaganda"?
If I found one personal reference to him as "Olgin was followed several speakers later by his fellow party delegate, Dr. A. Markoff, who has been equally successful in the professions of dental surgery and Stalinist officialdom" and also " Isn’t it strange, Dr. A. Markoff, D.D.S.?": https://marxists.catbull.com/archive/shachtma/1932/08/congress.htm
The only Comintern-like dentist associated with the CPUSA that comes to my mind is Dr. Philip Rosenbliett.
(Stay safe and sound)
