Eilif Dahl

Eilif Dahl (7 December 1916 – 17 March 1993) was a Norwegian botanist and politician for the Labour Party. He made contributions to the field of lichenology through his work on lichen chemistry and taxonomy, particularly his studies of Arctic flora. His most important publication was Studies in the Macrolichen Flora of SW Greenland (1950), which described several new lichen taxa. Dahl served as a professor of botany at the Norwegian College of Agriculture from 1965, was active in resistance work during the German occupation of Norway, and later became a board member of the Labour Party from 1965 to 1977. Throughout his career, he maintained connections between lichenology and other botanical disciplines, creating identification keys that proved valuable to researchers across Scandinavia and Australia.
