Carl Linnaeus (23 May 1707 – 10 January 1778), also known after his ennoblement as Carl von Linné  was a Swedish botanist, zoologist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus (after 1761 Carolus a Linné)

Background sketches and notes from his notebook 1811.

Linnaeus departed from Uppsala and travelled clockwise around the coast of the Gulf of Bothnia over the course of six months, making major inland incursions from Umeå, Luleå and Tornio. His observations became the basis of his book Flora Lapponica (1737) in which Linnaeus’ ideas about nomenclature and classification were first used in a practical way. Linnaeus kept a journal of his expedition which was first published posthumously as an English translation called Lachesis Lapponica: A Tour in Lapland (1811)
