Louis Jensen (19 July 1943 – 4 March 2021) is a Danish author and innovator in the international literary trends of flash fiction, metafiction, prose poetry, and magical realism.

[4] 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.

According to critic Anna Karlskov Skyggebjerg, "In most of Louis Jensen's books, the main character has something to do with the supernatural, the magic, or the fantastic.

As Skyggebjerg remarks, "In Jensen's books, there is a great deal of cruelty and evil, but also love and friendship between different creatures and humans.

He made the short list (5 authors, nominated from 34 countries) for the Hans Christian Andersen Award two times, in 2010 and again in 2016.

[16] In 2014, he was nominated for the Nordic Council Children and Young People's Literature Prize for his eighth collection of square stories, published in 2012.

The Nordic Council praised the "humour and seriousness" of Jensen's work, suggesting that his stories have "brought greetings from Hans Christian Andersen, Lewis Carroll and E. T. A. Hoffman and other great poets to all the children and adults who just wanted to read along.

He described his mother's childhood in the biographically based book, "En historie om seks søstre" ("A story of six sisters," Gyldendal, 2009).

According to Lise Kildegaard, these "ludic and lyrical" stories reveal Jensen's close observation of nature and his poetic appreciation of a world that combines in equal measure "familiarity and strangeness, commonplace reality and ecstatic vision.

The eleventh and final book in the series, illustrated by Lilian Brøgger and Maria Lundén, includes 134 pages of drawings, most of them in color.

According to critic Anna Karlskov Skyggebjerg, Brøgger "has given the texts new meanings without closing the openness to many interpretations that is one of their hallmarks."

"[25] In a review of the ninth volume of stories in Kristeligt Dagblad, Sara Nørholm writes that Brøgger's illustrations have been "kissed by Picasso, with his mouth full of peat and sunflowers.

She contributed to the more poetic and fairytale-like imagery of the 1980s, and has held her own in the postmodern and deconstructionist revival that has characterized the 1990s and the turn of the century.

This progress can be seen in Louis Jensen’s Hundrede firkantede historier 1-9 (Hundred square stories, 1-9, 1992-2014) where her illustrations developed from fine black and white lines to powerful colours to graphic and collage.
