Olof Fåhræus

Olof Immanuel Fåhræus (23 March 1796 – 28 May 1884), was a Swedish civil servant, politician and entomologist mainly interested in Coleoptera.

In 1840, a new Swedish government was formed under Arvid Mauritz Posse, then director general of the Customs Board.

In 1847, he asked to leave his post as minister and was succeeded by his twin brother Fredrik Fåhræus.

Instead, Fåhræus served as Governor of Gothenburg and Bohus County from 1847 to 1864 and then as chairman of the board of the Bank of Sweden from 1867 to 1872.

Fåhræus was elected a member of the Royal Swedish Academy of Sciences in 1840 and received an honorary doctorate from Uppsala University in 1877.
