In 2020, the Cosmoscow Foundation donated to Garage Archive Collection over 60 unique materials related to Andrei Sinyavsky: the samizdat literary and satirical magazine Ne unyvai (no. 17-18, January 1944) and Sinyavsky's letters from Syzran to Moscow to his mother Olga Chirkova and his childhood friend and future philologist and underground journalist Andrei Remizov. The archive is a unique source of information on the early life of Andrei Sinyavsky.
Andrei Sinyavsky (pseudonym Abram Terz; 1925–1997) was a writer, literary critic, and historian, a Soviet dissident, and a political prisoner. He was the author of short stories and essays, which were published in the West and (to an extent) in the USSR. In the fall of 1965 he was arrested together with Yuli Daniel on charges of anti‑Soviet propaganda. In February 1966, he was sentenced by the Supreme Court to seven years in a penal colony. The trial of Sinyavsky and Daniel is associated with the beginning of the second period of the democratic (dissident) movement in the USSR. In 1971, he was released early on the instructions of Yuri Andropov and in 1973 he emigrated to France.
Andrei Remizov (pseudonym I. Ivanov; 1924–2000) was a philologist and friend of Andrei Sinyavsky and Yuli Daniel. He worked as a researcher at the All‑Union State Library of Foreign Literature (Moscow), and in the 1980s was head of the research department of the State Public Historical Library (Moscow).
