Carl von Linné

Born in Småland in 1707, Carl von Linné—better known internationally as Carl Linnaeus—studied at Uppsala and later earned a medical degree in the Netherlands. He became one of Sweden’s most influential scientists, serving as a professor at Uppsala University and building a reputation through teaching, fieldwork, and an extraordinary drive to classify the natural world.

His most lasting achievement was the clear, consistent way he named and organized living things. In works such as Systema Naturae and Species Plantarum, he developed and spread binomial nomenclature, the two-part naming system that gives each species a genus and species name. That approach made it far easier for scholars across countries to talk about the same organisms, and it remains central to biology.

Linné was also an explorer, collector, and energetic observer of nature, especially plants. Even where later science moved beyond his ideas, his ambition to describe nature systematically changed biology for good. He died in Uppsala in 1778, but his influence still runs through botany, zoology, and the way science names the world.
