I did not know about the FDR connection. But should have.
Thanks.
Another interesting individual whose career is a nexus of communism and Wall Street is Felix Frankfurter, Supreme Court Justice.
You might want a drink before researching too much.
Another fellow with the Wall Street / communist alternating stripes is W. Averell Harriman. His mommy donated ten thousand acres outside New York City which became Harriman State Park.
Striking connections.
