George De Mohrenschildt's brother Dimitri Sergius corresponded with
Boris Souvarine, the self-educated pioneering Sovietologist, who wrote
the first biography of Joseph Stalin, published in 1935. For the next
sixty years he was a leading Sovietologist and anti-communist, founder
of L'Institut d'Histoire Sociale (Paris), as well as an author,
editor, historian, journalist and publisher.

From HSCA:
"De Mohrenschildt testified that his brother Dimitri remained a
"ferocious anti-Communist."(16) he served in the Czarist Russian
Imperial Navy.(17) After the Russian revolution, Dimitri von
Mohrenschildt joined anti-Communist groups and was jailed by the
Communists and sentenced to death.(18) He was released from jail in a
prisoner exchange with the help of a Polish Catholic bishop.(19)
Dimitri von Mohrenschildt emigrated to the United States in August
1920."

I wonder if Levine knew Boris was acquainted with Dimitri De
Mohrenschildt, George's brother.
Small world.
