Stanisław Jackowski (1887 in Warsaw – 1951 in Katowice) was a Polish sculptor, and nephew of novelist Bolesław Prus. In 1909-11 Jackowski studied sculpture at the Academy of Fine Arts in Kraków (Akademia Sztuk Pięknych) under Konstanty Laszczka, as well as the history of art at Kraków University. In 1911-12 he attended the Académie Colarossi in Paris, France.
Stanisław Jackowski was born in 1887 to Polish parents in Warsaw, in the part of Poland then ruled by the Russian Empire following the Partitions of Poland.
Jackowski completed his art studies before the First World War in Kraków, the Austrian-ruled part of Poland, and throughout the Interwar period lived and worked in Warsaw. He was a member, and for many years president, of the Rzeźba (Sculpture) Society.
Jackowski died in 1951 in Katowice, Poland.
In 1912 Jackowski designed the Powązki Cemetery tomb of his uncle, novelist Bolesław Prus. The monument bears on three sides, respectively, the writer's actual name Aleksander Głowacki, his dates of birth and death, and his pen name Bolesław Prus. On the fourth side is the inscription "Serce serc" ("Heart of hearts"), borrowed from the Latin inscription "Cor cordium" on the tomb of English Romantic poet Percy Bysshe Shelley in Rome's Protestant Cemetery; and below this inscription is the figure of a little girl embracing Prus' tomb — a figure emblematic of Prus' well-known empathy and affection for children.
