Noi (Noah) Abramovich Trotsky (Noi Abrámovic Tróckii) was a renowned Soviet architect (March 15, 1895 - November 19, 1940).
Trotsky was born in St. Petersburg to a family of a typesetter and went on to study art from the renowned painter, Nicholas Roerich. He graduated from the Petrograd Art Course in 1920, which would later become the Academy of Arts.
Trotsky was the apprentice of Ivan Fomin who was known at the "Red Doric". His training under Fomin incited a familiarity with classical forms. Trotsky's most famous work was in the Constructivist style but he would later turn to Neoclassicism in the 1930s. The Kirov District Administration building from 1938 expresses this transition most clearly.
Trotsky's best-known project is the House of Soviets (Saint Petersburg). At the year of its completion, the building was the largest office building in Saint Petersburg (then Leningrad). In March 1936, the Leningrad Soviets decided to relocate all the city's administration to a new site at the southern end of International Avenue. In open tender, Trotsky's project was selected over ten others. It was completed after Trotsky death, with co-authors Modest Shepilevsky and Yakov Lukin, and it features an impressive 11-meter-high frieze by Soviet sculptor Nikolai Tomsky.
Trotsky taught at the Academy of Arts' successor, VKhuTeIn, Higher Institute of Arts and Design. From 1929 he was a Professor at the Institute of Painting, Sculpture and Architecture. From 1939 Trotsky taught at the Saint-Petersburg State University of Architecture and Civil Engineering.
He died in 1940 and is buried at the Volkovo Cemetery in Saint Petersburg.
