Thanks> I forgot the name Myles Horton. He was the day-to-day manager of the Center while Dombrowski and Grossman provided guidance from the Party.
Don’t remember if Horton ever was identified as a Party member but the Communist Party wouldn’t have entrusted such an important recruiting and training school to someone they couldn’t trust.
Just for a history factoid. The last time I saw Carl and Anne Braden was 50 years ago this month at another CPUSA anti-intelligence front conference in DC, that of the National Committee to Abolish HUAC, which was changed at the meeting to NCAHISC.
I even carried some newspapers (The Patriot) for Carl to Union Station. Anne stayed around at the conference. She later went on to become a major Party leader in other southern operations and some black extremist fronts in North Carolina. Gotta hand it to her, she was a fireball, for the Soviets.
