Erasmus Benedicter (Benedigt) Kjerschow (Kjerskov) Zahl (19 January 1826 – 29 April 1900) was a privileged trader and an island owner at Kjerringøy in Nordland, Norway.
 Zahl is known as Nobel Literature Prize laureate Knut Hamsun's monetary supporter, and a representative of the old, traditional Nordland—Hamsun's ideal society—he is also internationally known through the character "Mack", who appears in several works of Hamsun, among them "Pan" (1894), "Dreamers" (1904), and "Benoni" and "Rosa" (1908).
Knut Hamsun (August 4, 1859 – February 19, 1952) was a major Norwegian writer, who was awarded the Nobel Prize in Literature in 1920.
 Hamsun's work spans more than 70 years and shows variation with regard to the subject, perspective and environment.
 He published more than 20 novels, a collection of poetry, some short stories and plays, a travelogue, and some essays.
The Knut Hamsun Centre (Norwegian: "Hamsunsenteret" ) is a museum and educational centre in Hamarøy in Northern Norway dedicated to the life and work of the writer Knut Hamsun.
Hamsun is a 1996 internationally co-produced drama film directed by Jan Troell, about the later life of the Norwegian author Knut Hamsun (Max von Sydow), who, together with his wife Marie Hamsun (Ghita Nørby), went from being a national hero to a traitor after supporting Nazi Germany during their occupation of Norway during World War II.
The Norwegian new realism was a literary movement that dominated Norwegian literature in the first half of the 20th century.
 Prominent examples include Knut Hamsun's later work, Sigrid Undset, Johan Falkberget, and Olaf Bull.
 Both Knut Hamsun and Sigrid Undset were awarded the Nobel Prize in Literature.
Tore Hamsun (6 March 1912 – 10 January 1995) was a Norwegian painter, writer, and publisher born in Hamarøy.
 He was the son of the Nobel Prize winning novelist Knut Hamsun and actress Marie Hamsun.
Growth of the soil (Norwegian Markens Grøde), is a novel by Knut Hamsun which won him the Nobel Prize in Literature in 1920.
 It follows the story of a man who settles and lives in rural Norway.
 First published in 1917, it has since been translated from Norwegian into languages such as English.
 The novel was written in the popular style of Norwegian new realism, a movement dominating the early 20th century.
 The novel exemplified Hamsun's aversion to modernity and inclination towards primitivism and the agrarian lifestyle.
 The novel employed literary techniques new to the time such as stream of consciousness.
 Hamsun tended to stress the relationship between his characters and the natural environment.
 Growth of the Soil portrays the protagonist (Isak) and his family as awed by modernity, yet at times, they come into conflict with it.
 The novel contains two sections entitled "Book One" and "Book Two".
 The first book focuses almost solely on the story of Isak and his family and the second book starts off by following the plight of Axel and ends mainly focusing on Isak's family.
Pan (also released under the title Two Green Feathers) is a 1995 Danish/Norwegian/German film directed by the Danish director Henning Carlsen.
 It is based on Knut Hamsun's 1894 novel of the same name, and also incorporates the short story "Paper on Glahn's Death", which Hamsun had written and published earlier, but which was later appended to editions of the novel.
 It is the fourth and most recent film adaptation of the novel—the novel was previously adapted into motion pictures in 1922, 1937, and 1962.
