Rudy Baker, a Communist Party United States of America official, is today best known for his role as head of the CPUSA"s underground secret apparatus.

He went to Moscow and trained at the International Lenin School from 1927 to 1930.
Baker shows up in the Venona project decryptions of Soviet codes under the cover name SON. He may also be RUDI. In these messages, SON is the head of the party"s covert arm or secret apparatus, which Baker took over in mid-1938 after the defection of Whittaker Chambers.
