Antoni Uniechowski, born on February 1903, in Vilnius, was a Polish draftsman, illustrator, and set designer. He came from an artistic family; his father, Janusz Radogost-Uniechowski, was an art collector, and his mother, Zofia from Jelskich, was artistically talented. After initial lessons at home, in 1916 he began studying at a Russian gymnasium in Mińsk Litewski. In 1918, the family moved to Warsaw, where Uniechowski continued his education at the St. Stanislaus Kostka Gymnasium, while also attending evening drawing courses led by Feliks Słupski at the Wojciech Gerson School.
In 1924, he registered as a listener at the School of Fine Arts in Warsaw, and in 1930, he completed his artistic studies, training under Karol Tichy in painting and Wojciech Jastrzębowski in design. Uniechowski was active as a poster artist, film and theater set designer, and primarily as a book illustrator. His style was characterized by light, free drawings made with ink and watercolor. He collaborated with numerous publishing houses, illustrating works such as Voltaire's "Philosophical Tales," Henryk Sienkiewicz's "The Deluge," Ignacy Krasicki's "Monachomachia," Stefan Żeromski's "Ashes," and Bolesław Prus's "The Doll" and "Emancipated Women." From 1945 to 1956, he collaborated with the weekly magazine "Przekrój" and was a member of the Professional Block of Plastic Artists. He made his debut as a set designer at the Powszechny Theater in 1957 and also created sets for Television Theater and designed theatrical and film posters.
Antoni Uniechowski passed away on May 23, 1976, in Warsaw and was buried at the Military Cemetery at Powązki.
