The Danish author Louis Jensen (19 July 1943 – 4 March 2021) was an innovator in the international literary trends of flash fiction, metafiction, prose poetry, and magical realism. While he published more than 90 books for both adults and children, he was best known for his children's books, which include picture books, short stories, flash fiction, creative nonfiction and novels. His work is characterized by wordplay and playful experiments in form and structure, which have led critics to draw comparisons to Borges, Calvino, Gogol, and the poetry of the Oulipo movement. His work is also rooted in the fairy tale and folk tale tradition, and is deeply influenced by the Danish author Hans Christian Andersen.
