Yuri Mikhailovich Lotman (Russian: Ю́рий Миха́йлович Ло́тман, Estonian: Juri Lotman) (28 February 1922 – 28 October 1993) was a prominent literary scholar, semiotician, and cultural historian, who worked at the University of Tartu. He was a member of the Estonian Academy of Sciences. He was the founder of the Tartu-Moscow Semiotic School and is considered to be the first Soviet structuralist because of his early essay On the Delimitation of Linguistic and Philological Concepts of Structure (1963) and works on structural poetics. The number of his printed works exceeds 800 titles; and his archive (which is now kept at the University of Tallinn and at the Tartu University Library) which includes his correspondence with a number of Russian intellectuals, is immense.
Yuri Lotman was born in the Jewish intellectual family of lawyer Mikhail Lotman and Sorbonne-educated dentist Aleksandra Lotman in Petrograd, Russia. His elder sister Inna Obraztsova graduated Leningrad Conservatory and became a composer and lecturer of musical theory, his younger sister Victoria Lotman was a prominent cardiologist, and his third sister Lidia Lotman was a scholar of Russian literature of the second half of the 19th century on staff at the Institute for Russian Literature of the Russian Academy of Science (Pushkin House) (she lived in Saint-Petersburg).
Lotman graduated from secondary school in 1939 with excellent marks and was admitted to Leningrad State University without having to pass any exams. There he studied philology, which was a choice he made due to Lidia Lotman's university friends (actually he attended university lectures in philology whilst he was still at secondary school). His professors at university were the renowned lecturers and academicians – Gukovsky, Azadovsky, Tomashevsky and Propp. He was drafted in 1940 and during World War II served as a radio operator in the artillery. Demobilized from the army in 1946, he returned to his studies in the university and received his diploma with distinction in 1950. His first published research papers focused on Russian literary and social thought of the 18th and 19th century.
