Sergey Radlov was a theatre director, educator, playwright, theatre theorist and historian. Honoured Artist of the RSFSR (1933) and Honoured Art Worker of the RSFSR (1940). Born in 1892 in St. Petersburg into the family of philosopher Ernest Radlov, he graduated from the historical-philological faculty of St. Petersburg University (1916). From 1913, he collaborated with Vsevolod Meyerhold's Studio and the journal "Love for Three Oranges". In 1919, he founded the People's Comedy Theatre, where he developed ideas of popular spectacle, employing techniques of clowning, buffoonery, and eccentricity. During the 1920s–1930s, he directed performances at the Leningrad Academic Drama Theatre (now — Alexandrinsky Theatre) and the Theatre of Opera and Ballet (now — Mariinsky Theatre). Among his landmark productions were "Othello", "Lysistrata", "Eugen the Unfortunate", the operas "The Love for Three Oranges" and "Wozzeck", and the ballet "The Fountain of Bakhchisaray". From 1928, Radlov led the Young Theatre he had founded, where he devoted particular attention to Shakespearean repertoire: "Othello", "Romeo and Juliet", and "Hamlet". In 1935, he staged "King Lear" at the State Jewish Theatre (GOSET), with Solomon Mikhoels in the title role. During the Great Patriotic War, Radlov's theatre was on tour abroad and found itself in occupied territory. After the liberation of France, the director and his troupe returned to the USSR but were subsequently repressed. Radlov was sent to a labour camp near Rybinsk; his wife, the poet Anna Radlova, was also arrested and died in captivity in 1949. Radlov was released in 1953 but denied rehabilitation and the right to reside in Moscow or Leningrad. In 1957, he was exonerated and officially rehabilitated. In his final years, he worked at theatres in Daugavpils and Riga, where he realised his "great Shakespeare cycle": "Hamlet", "King Lear", and "Macbeth". The online collection of the Bakhrushin Theatre Museum features set designs for performances directed by Sergey Radlov, posters, photographs, and archival documents reflecting his creative journey.
