Mikhail Ryumin
Mikhail Dmitrievich Ryumin (1 September 1913 – 22 July 1954) was a Soviet security officer in the Ministry of State Security (MGB) who advanced rapidly during World War II and the late Stalin era, culminating in his appointment as deputy minister in October 1951.[1][2] As a protégé of Viktor Abakumov, Ryumin led investigations into major cases, including the 1948 "Marshal's Plot" against Georgy Zhukov and the Leningrad Affair, employing torture to extract confessions.[2] He spearheaded the Doctors' Plot in 1951–1953, fabricating accusations that a group of mainly Jewish physicians conspired to murder Soviet leaders through medical malpractice, which escalated into a broader antisemitic campaign.[2][3] Following Joseph Stalin's death on 5 March 1953, Ryumin was arrested on 17 March by Lavrentiy Beria's orders, dismissed from his posts, and convicted in July 1954 of falsifying evidence, torturing suspects, and other crimes, leading to his execution by firing squad.[1][3] His downfall reflected the post-Stalin reckoning with fabricated purges, though he received no posthumous rehabilitation.[2]
