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

Life

Hansteen studied in Copenhagen, the rights, then mathematics teacher in Frederiksborg on Zealand and was received on the basis of a treatise on terrestrial magnetism in 1814 a reputation as a professor at the University of Christiania. His " studies on the magnetism of the earth" ( Christiania 1819, with Atlas ) gave reason to believe that magnetic observations were made after his trial on almost all expeditions made ​​since then. Hansteen himself undertook many journeys for this purpose, namely 1828-1830 and such in the company of Georg Adolf Erman of Berlin and Lieutenant Due of the Norwegian Navy to Siberia to Irkutsk and Kjachta. The results of this trip can be found in the " Travel Memories from Siberia" ( German Sebald, Leipzig 1854) and in the main work: "Results of magnetic, astronomical and meteorological observations on a trip to Siberia" ( Christiania 1863). Under Hansteen line the observatory were created to Christiania and the magnetic observatory in the park of the observatory (see "Description and Location of the University Observatory in Christiania ", Christiania, 1849). Hansteen gave not only at the University but also at the Artillery and Engineering School Lectures on applied mathematics and directed since 1837 the trigonometric survey of Norway; was also in the great Russian- Scandinavian latitude measurement under his leadership the gamut from 1845-1860 Fuglenäs at Hammerfest under 70 ° 40 'to Atjik under 68 ° 54' measured. He died in 1873.

The lunar crater Hansteen is named after him.
