At the start of the First World War, her family fled to Vienna, returning to Poland in 1918. It was in this year that Korn's first published works appeared, in Nowy Dziennik, a Zionist newspaper, and in Glos Przemyski, a socialist journal. These items were published in Polish, but a year later she published her first Yiddish poem in the Lemberger Tageblatt. Her recognition grew with the publication of her first volumes of poetry: Dorf (Village, 1928) and Royter mon (Red Poppies, 1937). Her first collection of prose, Erd (Land), was published in 1936.
Following the German invasion of eastern Galicia in June 1941, Korn fled to Uzbekistan, before moving to Moscow, where she remained until the end of the war. She returned to Poland in 1946, immigrating to Montreal, Canada in 1948.
Korn's fourth collection of poetry, Heym un heymlozikayt (Home and Homelessness), was published in 1948. She remained in Montreal, writing poetry, until her death in 1982.
