Polish journalist, short-story writer, and novelist who was one of the leading figures of the Positivist period in Polish literature following the 1863 January Insurrection against Russian rule.

Born to an impoverished gentry family, Prus was orphaned early in life and struggled unsuccessfully to complete his education. As a young man, he took an active part in the January Insurrection. Throughout much of his life he contributed articles called “chronicles” to daily papers and periodicals; these reveal the talent for detailed observation and lively presentation that was to make his novels and short stories so effective.

A strong proponent of Poland's version of Positivist philosophy, Prus gradually changed from a journalistic career to fiction, and became known as a leading Polish prose writer of the second half of the 19th century. Among his best-known short stories are "Anielka" (1880; “Annie”), "Katarynka" (1881; “The Barrel Organ”), and "Kamizelka" (1882; “The Waistcoat”). "The Barrel Organ" and "The Waistcoat" are included in the English-language volume of Prus's stories entitled The Sins of Childhood and Other Stories (1996). As a novelist, he was considered a major Realist, with his Lalka (1890; “The Doll,” filmed 1969) giving a complex picture of Warsaw's social classes at the end of the century. In Faraon (1897; The Pharaoh and the Priest) he used the conflict between ruler and clergy in ancient Egypt as a metaphor for his depiction of the power struggle in modern society.
