1922 Encyclopædia Britannica/Hildebrandsson, Hugo Hildebrand

HILDEBRANDSSON, HUGO HILDEBRAND (1838-       ), Swedish meteorologist, was born at Stockholm Aug. 19 1838, and was educated at the Stockholm gymnasium and the university of Upsala, where he took his doctor's degree in 1858, becoming doctor of physics in 1866. In 1878 he was appointed first professor of meteorology at Upsala and director of the meteorological observatory there, retaining these posts until 1906. He was a prominent member of the International Meteorological Committee, and for some years served as its secretary, while he also sat on the Nobel Committee for Physics, in 1900 obtaining the Nobel prize. In 1880 he was elected an hon. fellow of the Royal Meteorological Society of London, which in 1920 awarded him the Symons gold medal, being also a member of many foreign scientific societies.

As a meteorologist Hildebrandsson is remarkable for his researches into the subject of cloud, and in 1880 was requested by the International Meteorological Committee to prepare the International Cloud Atlas, a work carried out in conjunction with Leon Teisserenc de Bort. Many further observations were subsequently incorporated in Les bases de la météorologie dynamique (1907), in which Teisserenc de Bort again collaborated. His papers on centres of action of the atmosphere mark a great advance in seasonal forecasts.
