Jack Soble
Lithuanian spy for the Soviet Union

Jack Soble (May 15, 1903 – 1967) was a Lithuanian who, together with his brother Robert Soblen, penetrated Leon Trotsky's entourage for Soviet intelligence in the 1920s. Later, in the United States, he was jailed, with his wife Myra, on espionage charges. He was born in Vilkaviskis, Lithuania as Abromas Sobolevicius and sometimes used the name Abraham Sobolevicius or Adolph Senin.
Biography
Early life
Soble was born in 1903 as Abromas Sobolevicius in, then-Russian controlled, Lithuania to a wealthy Jewish family. Soble travelled to Leipzig in 1921, to attend college, while there he joined the German Communist Party. In 1927 he travelled to the Soviet Union marrying before returning to Germany. Soble studied briefly at the University of Berlin where he became a Trotskyist which led to his expulsion from the Communist Party and the university.
Spying career
Soble would claim decades later that he was coerced by Soviet agents to become a spy in 1931 after his wife returned to the USSR to visit her sick mother and threats to her safety were made if he did not cooperate. These claims are considered suspect as there is evidence that Soble had earlier contact with Stalin's agents.
Soble, who now adopted the name Abraham Senin, became publicly known as a prominent member of the German Trotskyist circle, visiting Leon Trotsky himself on at least two occasions.

Why this record matters
“Jack Soble” is worth following because a concise public description often conceals a longer documentary argument. Here, Jack, Soble and Lithuanian provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 10, 2026. The linked authority identifier is Q5038145. VIAF identifies the subject as 3011167025443453390001. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1903, 1967, 1921 and 1927.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
