He was born in Tverá, Skagafjörður, Iceland to farmers Ólafur Jónsson and Kristín Björnsdóttir, and was educated at the Royal Danish Academy of Fine Arts in Copenhagen. From 1784 he lectured at the Kongsberg School of Mines, in mathematics and drawing, later also in jurisprudence, and was appointed professor from 1794.
