Hans Strøm was the first Norwegian who gave species descriptions for Norwegian animals. The results of his research was published as Physisk og Oeconomisk Beskrivelse over Fogderiet Søndmør I-II (Copenhagen, 1762-1766), a work that established his reputation as a scientific authority. He followed up this work with a number of articles, particularly where the natural sciences were strongly represented. He co-founded the Royal Norwegian Society of Sciences and Letters in 1760, with Gerhard Schoning, the historian, and Johan Ernst Gunnerus, bishop of Trondheim. In 1779, Strøm was elected a foreign member of the Royal Swedish Academy of Sciences. He was also elected as a member of a number of science academies in Norway, Denmark and Germany.
