Lev Sedov

son of Leon Trotsky, communist oppositionist and writer (1906–1938)

The Red Book on the Moscow Trials, published in 1936, served as the primary instrument for challenging the judicial narrative established by the Soviet regime during that era. Authored by Lev Sedov, the text provided a systematic critique of the frame-ups that defined the Moscow trials, eventually securing its place as a central document in historical efforts to discredit those proceedings.

Early Life and Political Formation

Born in 1906 in Saint Petersburg, Lev Sedov was the son of Leon Trotsky and Natalia Sedova. To distance himself from any perception of privilege following the October Revolution, he lived independently from his parents. In 1925, at the age of 19, he married and had a son, Lev, one year later. His formal education included studies at the Technische Universität Berlin.

Exile and Trotskyist Activity

Sedov accompanied his parents into exile in 1929. By 1931, he relocated to Berlin, where he sought medical treatment for an eye condition. During this time, he contributed to the Russian-language Bulletin of the Opposition as both an editor and writer. He facilitated the creation of a political bloc in 1932, aiming to organize the anti-Stalinist opposition within the USSR. By 1933, he moved to Paris, operating as a laborer while remaining an active figure in the international movement led by his father.

Death in Paris

In February 1938, Sedov suffered an acute appendicitis attack. Mark Zborowski, an NKVD operative acting as a confidant, facilitated his admission to the Clinique Mirabeau rather than a public medical facility. The clinic, which held ties to Soviet intelligence, performed an appendectomy from which Sedov suffered fatal complications. Following his death in a Paris hospital, he was buried at the Cimetière parisien de Thiais.
