**Jakob Rudolf Keyser** (1 January 1803 – 9 October 1864) was a Norwegian historian, archaeologist and educator.[1]

## Biography

Jakob Rudolf Keyser was born in [Christiania](/source/Oslo), now [Oslo, Norway](/source/Oslo,_Norway). He was the son of Bishop [Johan Michael Keyser](/source/Johan_Michael_Keyser) (1749–1810) and his second wife Kirsten Margarethe Wangensteen. He was the brother of professor Fredrik Wilhelm Keyser and theologian Christian Nicolai Keyser.[2]

Following studies in [Iceland](/source/Iceland), Rudolf Keyser was appointed as a docent at the [Royal Frederick University](/source/University_of_Oslo) in Christiania in 1828. He became a professor in 1831 and remained at the university until he retired in 1862. Keyser was also the first manager for the [University Museum of National Antiquities](/source/University_of_Oslo). He cataloged and categorized prehistoric artifacts which had originated from excavations. He did so utilizing the chronological system developed by [Christian Jürgensen Thomsen](/source/Christian_J%C3%BCrgensen_Thomsen).[3]

Keyser was most commonly associated with the [Theory on immigration to Norway](/source/Theory_on_immigration_to_Norway). Keyser was a supporter of the migration theory that the Norse tribes had wandered into Norway from the north and east, a view also shared by [Peter Andreas Munch](/source/Peter_Andreas_Munch), a former student of Keyser. This theory was inspired in part by the earlier works of [Gerhard Schøning](/source/Gerhard_Sch%C3%B8ning). The theory was commonly denounced by many Norwegian historians especially by [Ludvig Kristensen Daa](/source/Ludvig_Kristensen_Daa). Rudolf Keyser became a knight in the Order of St. Olav in 1847.[4]
