Harald Nicolai Storm Wergeland (27 May 1814 – 12 October 1893) was a Norwegian military officer, politician and mountaineer. Having reached the rank of Major General by 1859, he served as Minister of the Army for several periods between 1857 and 1868. He later became Lieutenant General. He had several notable family members.
Wergeland was born in Bergen as the son of Ingeborg Bergithe Lassesen Wergeland and her husband Gierth Christian Storm. A nephew of priest and politician Nicolai Wergeland and cousin of the poet Henrik Wergeland, feminist writer Camilla Collett and military officer Oscar Wergeland, Harald Wergeland grew up in their household.
In October 1841 he married Anne Sofie Schøyen, born in 1816 in Sør-Odal. The couple had several children.
Wergeland enrolled at the Norwegian Military Academy (Krigsskolen) at the age of twelve, graduating at the age of seventeen. He held the military rank of Second Lieutenant. Three years later he advanced to Premier Lieutenant and began holding lectures on artillery at the Norwegian Military Academy. He was later appointed aide-de-camp of King Oscar of Sweden and Norway.
Around 1840 Wergeland was assigned work with cartography. When exploring the Jotunheimen mountain range, he was among the first ascenders of several mountains, including Glittertind (2,464 metres (8,084 ft)). In 1857 he was promoted to the rank of Colonel, and made chief of the General Staff. In 1859 he had been promoted to Major General.
