Yuli Daniel, Russian author and poet (b. 1925)

Yuli Markovich Daniel (Russian: Ю́лий Ма́ркович Даниэ́ль, IPA: [ˈjʉlʲɪj ˈmarkəvʲɪtɕ dənʲɪˈelʲ] (listen); 15 November 1925 — 30 December 1988) was a Russian writer and Soviet dissident known as a defendant in the Sinyavsky–Daniel trial in 1966.

Daniel wrote and translated works of stories and poetry critical of Soviet society under the pseudonyms Nikolay Arzhak (Russian: Никола́й Аржа́к, IPA: [nʲɪkɐˈlaj ɐrˈʐak] (listen)) and Yu. Petrov (Russian: Ю. Петро́в, IPA: [ˈju pʲɪˈtrof] (listen)) published in the West to avoid censorship in the Soviet Union. Daniel and Andrei Sinyavsky were convicted of Anti-Soviet agitation in a show trial, becoming the first Soviet writers convicted solely for their works and for fiction, serving five years at a Gulag camp and prison.
