Rolf Jacobsen (8 March 1907 – 20 February 1994) was a Norwegian writer. Jacobsen could be said to be the first modernist writer in Norway. Jacobsen's career as a writer spanned more than fifty years. He is one of Scandinavia’s most distinguished poets, who launched poetic modernism in Norway with his first book, Jord og jern in 1933. Jacobsen's work has been translated into over twenty languages. The central theme in his work is the balance between nature and technology – he was called "the Green Poet" in Norwegian literature. Youth Rolf Jacobsen was born in Oslo (then called Kristiania), as the son of Martin Julius Jacobsen (1865–1944), who had completed both medical and dental school, and Marie (Nielsen) Jacobsen (1880–1953) a nurse. At the age of six he moved with his family to Åsnes, where Martin Jacobsen had obtained a post as a school dentist. Rolf was educated by his mother, who had completed one year of teacher's training. In 1920 he moved to Oslo and entered a private school. During these years his uncle, who was a railway engineer, looked after him. Jacobson continued his studies at the University of Oslo for five years without graduating. In 1927 he served in the Norwegian army for six weeks. From 1937 to 1939 he was a board member of Hedmark Labour Party.

Jacobsen's diverse literary and other artistic influences included the Poetic Edda, Karel Čapek's play R.U.R., and Carl Sandburg's poetry. The title of the collection also suggests a cyclic relationship between nature and technology. In 1934 Jacobsen returned to Åsnes to take care of his father. He had joined a socialist intellectual group, Clarté, and in Åsnes he became a member of the Labor Party Leadership for Hedmark County. In Åsnes, Jacobsen worked for the daily newspaper Kongsvinger Arbeiderblad, which was supported by Labor. Jacobsen's second collection of poems, Vrimmel (1935), revealed his underlying dismay at modern civilization. Jacobsen rejected Marinetti's manifesto, "We wish
