Carl Linnaeus (/lɪˈniːəs, lɪˈneɪəs/;[1][2] 23 May[note 1] 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné[3] (Swedish pronunciation: [ˈkɑːɭ fɔn lɪˈneː] (listen)), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy".[4] Many of his writings were in Latin; his name is rendered in Latin as Carolus Linnæus and, after his 1761 ennoblement, as Carolus a Linné.
