Carl Linnaeus

About this figure

Carl Linnaeus (1707–1778) was a Swedish botanist and physician who created the systematic framework for naming and classifying living organisms that biologists still use today. Trained in medicine and botany at the universities of Lund and Uppsala, he developed an early and lasting fascination with plants that shaped nearly everything he later accomplished, including a medical career he pursued partly as a practical necessity alongside his true interest in natural history.

In 1732, the young Linnaeus undertook a demanding scientific expedition through Lapland, in far northern Scandinavia, traveling largely alone and on foot or horseback through difficult terrain to study the region's plants, animals, minerals, and the customs of the Sámi people, an experience he recorded in journals later published, well after his death, as Lachesis Lapponica. The expedition supplied specimens and observations that fed directly into his later classification work and gave him firsthand material distinct from the herbarium specimens most of his contemporaries relied on.

Linnaeus's central and lasting achievement was binomial nomenclature, the convention of giving every species a two-part Latin name -- genus followed by species, as in Homo sapiens -- which he applied systematically across the natural world in his major works Systema Naturae and Species Plantarum. Before Linnaeus, naturalists commonly used long, inconsistent descriptive Latin phrases to identify organisms; his simplified two-name system, combined with a nested hierarchy of classification ranks, brought order to a rapidly growing body of specimens flowing into Europe from global exploration and trade, and it remains, with modifications, the basis of scientific naming today. He trained a network of students, sometimes called his "apostles," who traveled the globe collecting specimens and sending them back to Uppsala, vastly expanding the scope of his classification project during his own lifetime. He was ennobled by the Swedish crown later in life and remained an active professor and correspondent with naturalists across Europe until his death in 1778.
