Anastas Mikoyan
Antonov-Ovseyenko was the first former Trotskyist to be posthumously rehabilitated, and in 1956 was named in a speech by Anastas Mikoyan to the 20th party congress of the CPSU. Later, his son Anton, a historian, feared that he was to be 'un-rehabilitated', and fought a long rearguard battle to protect his reputation.
