Jacob Smith Jarmann was born
Jacob Smith Jarmann was born in Nord-Fron in Gudbrandsdalen. He is best known as the designer of the Jarmann rifle. Originally he intended to pursue a military career and took the officer's examination in 1840, but he received such poor marks in German that he gave it up.

Around 1838 Jarmann is said to have designed a single-shot breech-loading rifle for paper unit cartridges. Despite favorable comments, it was never adopted by the army because its rate of fire, 13 rounds per minute, implied enormous ammunition consumption for the time. Jarmann therefore set rifle design aside for a while.

In 1854 he founded Nylands Verksted and led it until 1878. The workshop built steamships and technical machinery, but in his spare time Jarmann also worked on firearms designs. In 1870 he completed a single-loader that became the precursor to a 10.15 mm repeating rifle with an 8-round tubular magazine in the stock. After extensive trials, this rifle was adopted as the Norwegian army rifle in 1881.
