Aniela Gruszecka (1884–1976) was a Polish writer, literary critic, and author of historical novels for children and young people.

[1][2] Gruszecka was born on 18 May 1884 in Warsaw, the daughter of Artur Gruszecki [pl], a novelist and publisher, and Józefa Certowicz, whose family came from Ukraine.

This marriage was later annulled and on 30 July 1913, she married Kazimierz Nitsch (1874–1958), a wealthy professor of linguistics at the Jagiellonian University, ten years her senior, who would become president of the Polish Academy of Arts and Sciences.

Her next book for adults, Przygoda w nieznanym kraju (Adventure in an Unknown Country), published in 1933 originally in instalments, was set in the intellectual and artistic circles of Kraków that she knew so well.

[1][2][3][4][5][6][7][8] Gruszecka also wrote historical novels for young people, notably: Król (King - 1913), W grodzie żaków (In the students' town - 1913), Od Karpat nad Bałtyk (From the Carpathians to the Baltic Sea - 1946), Nad jeziorem (By the Lake - 1921) and Powieść o kronice Galla (The Chronicle of Gallus Novel – Six volumes, 1960–1970).

In the same magazine she also published reviews of several famous debuts by young writers, such as books by Witold Gombrowicz, Adolf Rudnicki and Zbigniew Uniłowski.

[2][3][4][7] On 10 November 1933, "for her merits in the field of literature", primarily the book, Adventure in an Unknown Country, Gruszecka was awarded the Knight's Cross of the Order of Polonia Restituta by the president of the Republic of Poland, Ignacy Mościcki.
