 One of these early cases was that of party official Sergei Pisarev.Pisarev was arrested after criticizing the work of the Soviet secret police in the context of the so-called Doctors' Plot, an anti-Semitic campaign waged at Stalin's instructions that should have brought about a new terror wave in the Soviet Union and possibly the extermination of the remaining Jewish communes that had outlived the Second World War.Pisarev was committed to the Special Psychiatric Hospital in Leningrad which along with an analogous hospital in Sychevka has started functioning since the Second World War.
