Friherr Nils Adolf Erik Nordenskiöld (18

Friherr Nils Adolf Erik Nordenskiöld (18 November 1832, Helsinki, Finland – 12 August 1901, Dalbyö, Södermanland, Sweden) was a Finnish baron, botanist, geologist, mineralogist and arctic explorer of Finland-Swedish origin. He was a member of the prominent Finland-Swedish Nordenskiöld family of scientists.

Born in the Grand Duchy of Finland at the time it was a part of the Russian Empire, he was later, due to his political activity, forced to live in political exile in Sweden, where he later would become a member of the Parliament of Sweden and the Swedish Academy. He is most remembered for the Vega expedition along the northern coast of Eurasia, which he led in 1878 and 1879. This was the first complete crossing of the Northeast Passage.
