Henrik Mohn

Henrik Mohn (15 May 1835 – 12 September 1916) was a Norwegian astronomer and meteorologist. Although he enrolled in theology studies after finishing school, he is credited with founding meteorological research in Norway, being a professor at the Royal Frederick University and director of the Norwegian Meteorological Institute from 1866 to 1913.

He was born in Bergen as the son of Albert Henrik Mohn (1811–1894) and Ida Neumann (1814–1864). He was a brother of Jakob and Emanuel Mohn. On the maternal side, he was a grandson of bishop Jacob Neumann.

He was married twice. In December 1863 he married Louise Nicoline Rieck (1836–1866). After she died, he married Julie Birgitte Dyblie (1847–1928) in July 1871. He was a granduncle of Frank and Albert Henrik Mohn, and his niece Hanna married physician and politician Nils Yngvar Ustvedt.

He finished his secondary education at Bergen Cathedral School in 1852, and then enrolled at the Royal Frederick University. He originally studied theology, then switched to physics after attending lectures in that subject. He continued to study astronomy and mineralogy, graduating in the latter subject in 1858. To facilitate learning, he built his own telescope. In 1860 he was hired as a research fellow of astronomy, having delivered an esteemed paper on the orbits of comets in the same year. In 1861, when long-time professor Christopher Hansteen retired from an active academic career, Mohn became the new manager of the city astronomical observatory.
