Friherre Nils Ericson was a Swedishmechanical engineer. He became a prominent Swedish canal and railway builder. Born Nils Ericsson, he was raised to the untitled nobility by king Oscar I of Sweden in 1854, and with this he reverted to a spelling of his surname with only one "s". In 1859 he was made a Friherre, the 403rd such elevation to Sweden's titled nobility.
Background
John and Nils were born in Långbanshyttan, Värmland, Sweden and received no formal education, but were taught the rudiments of mechanics from an early age by their father, Olof Ericsson. Olof worked as the superintendent of a mine in Värmland until he lost money in speculations and had to move his family to Forsvik, Västergötland, in 1810. There Olaf became a director of blastings during the excavation of Sweden's Göta Canal. He secured permission for his sons to draw in the office of the draughtsmen of the canal company, where they also learned to draw maps, and he persuaded Lieutenant Brandenburg of the Navy Mechanical Corps to teach them the art of shading and 'finishing off' mechanical drawings before they were in their teens. Their extraordinary skills were noted by Baltzar von Platen, the architect of the Göta Canal, and they were soon dubbed cadets of mechanics of the Swedish Navy and engaged as trainees at the canal enterprise. When two engineers sent to England by Count Platen to obtain information about canal construction returned in 1815 and began to instruct a number of cadets of the Swedish Corps of Mechanical Engineers, the Ericsson brothers were among them; Nils being then twelve years old and John eleven.
Career
In 1823 Nils Ericson joined the Engineering corps of the Swedish Army as a second lieutenant, but in 1830 he transferred to the Navy Mechanical Corps. In 1833 he married a daughter of Count von Schwerin in Östergötland. Between 1830 and 1850 Nils Ericson planned and directed the construction of the canals at Stallbacka, Säffle, Karlstad and Albrektsund. He also led the construction of the Saimaa Canal in Finland, the reconstruction of the Trollhätte Canal in Trollhättan Municipality and the floodgate at Stockholm. In 1845, he was elected a member of the Royal Swedish Academy of Sciences. After 1850 he was primarily occupied with the design and construction of the Swedish state-owned railway system. At the same time he led the planning of the Dalsland Canal while construction there was being led by his son Werner. Sweden started building railways later than many other European countries, having hesitated under heavy debate for several years because of the costs and other issues. Following the Riksdag's decision in 1854, Erikson was chosen to lead the project of building the main lines. There was also a decision that, for military reasons, the railways should avoid the coasts as much as possible. His proposal was that the line between Gothenburg and Stockholm should run south of Lake Mälaren to avoid competition with shipping. He also proposed that the line between Malmö and Stockholm should go north via Nässjö to meet up with Western Main Line at Falköping until the Western's eastward construction reached Katrineholm, where a better junction could be built with a southern line heading directly to Nässjö. This line was called Eastern Main Line but has in modern times been defined to be part of the Southern Main Line. Ericson's proposal also included the railway between Stockholm and Ånge and Main Line Through Upper Norrland which runs between Bräcke and Boden. A railway between Oslo and Laxå was also planned, to connect with Western Main Line. The first parts of the Western and Southern lines were opened in 1856. Ericson resigned in 1862 when all of the Western line opened, and in 1864 the Southern line was opened in its entirety. Northwestern line was opened in 1871, Eastern line in 1874, Northern line in 1881 and the line through Upper Norrland in 1894. When Ericson resigned in 1862 his authority was divided between two agencies until the formation of Kungliga Järnvägsstyrelsen in 1888. Ericson died in Stockholm in 1870, aged 68, and lies buried in Stockholm's Northern Cemetery.
