He is known by the epithet "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). Linnaeus was born in the countryside of Småland, in southern Sweden.

Carolus linnaeus is the father of taxonomy. I think he itself described the word.
