Boris Yefimov was a Soviet and Russian graphic artist, known as a master of political caricature. Born in Kyiv into the family of a craftsman, he began drawing in childhood, and his first publications appeared before the Revolution. He did not receive formal artistic training. In the 1920s, he worked for Ukrainian newspapers, then moved to Moscow and began collaborating with major national publications, including “Pravda”, “Izvestia”, and the magazine “Krokodil”, among others. During the Great Patriotic War, he created satirical images of the USSR’s enemies. After the war, he worked at the Nuremberg Trials, making sketches from life. In the postwar decades, he continued publishing caricatures, headed the “Agitplakat” association, and remained active in public and artistic life. In addition to caricatures, he illustrated books, designed stage productions, and worked in animation. In 1967, he published a memoir about his brother, Mikhail Koltsov. In his later years, he continued drawing and writing memoirs. He died in Moscow in 2008. The Bakhrushin Theatre Museum collection preserves costume designs, playbills, and scenery designs created by Boris Yefimov.
