Christopher Hansteen (born September 26, 1784 in Christiania (now Oslo), † April 11, 1873 there ) was a Norwegian astronomer .

Life

Hansteen studied law in Copenhagen, then mathematics, became a teacher in Frederiksborg on Zealand and was appointed professor at Christiania University in 1814 because of a paper on geomagnetism . His “Investigations into the Earth's Magnetism” (Christiania 1819, with Atlas) gave rise to the fact that magnetic observations were made according to his method on almost all expeditions made since then. While observing terrestrial magnetism, he was in contact with Carl Friedrich Gauß .

Hansteen himself undertook many trips for this purpose, including one from 1828–1830, accompanied by Georg Adolf Erman from Berlin and Lieutenant Due from the Norwegian Navy to Siberia as far as Irkutsk and Kjachta . The results of this trip can be found in the "Travel memories from Siberia" (German by Sebald, Leipzig 1854) and in the main work: "Results of magnetic, astronomical and meteorological observations on a trip to Siberia" (Christiania 1863). The observatory at Christiania and the magnetic observatory in the park of the observatory were laid out under Hansteen's direction (see “Description and location of the university observatory in Christiania”, Christiania 1849).

Hansteen gave lectures on applied mathematics not only at the university, but also at the artillery and engineering school, and since 1837 headed the trigonometric survey of Norway. Under his direction, during the great Russian-Scandinavian latitude measurement from 1845 to 1860, the arc from Fuglenäs near Hammerfest was measured under 70 ° 40 'to Atjik under 68 ° 54'. Hansteen died in 1873.

Since 1821 he was a foreign member of the Bavarian Academy of Sciences . In 1830 he became an honorary member of the Russian Academy of Sciences in St. Petersburg and in 1833 a corresponding member of the Académie des Sciences . In 1840 he was elected to the Göttingen Academy of Sciences , 1845 to the Royal Society of Edinburgh and 1863 to the American Academy of Arts and Sciences .

The Hansteen lunar crater and Mons Hansteen are named after him.
