Linnaeus is credited with establishing the idea of a hierarchical structure of classification which is based upon observable characteristics.

Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as Carl von Linné (help·info), May 23 [O.S. May 12] 1707 – January 10, 1778) was a Swedish botanist, physician, and zoologist, who laid the foundations for the modern scheme of binomial nomenclature. He is known as the father of modern taxonomy, and is also considered one of the fathers of modern ecology.

Linnaeus was born in the countryside of Småland, in southern Sweden.

The Swiss philosopher Jean-Jacques Rousseau sent him the message: "Tell him I know no greater man on earth."

The German writer Johann Wolfgang von Goethe wrote: "With the exception of Shakespeare and Spinoza, I know no one among the no longer living who has influenced me more strongly."

Swedish author August Strindberg wrote: "Linnaeus was in reality a poet who happened to become a naturalist".

In botany, the author abbreviation used to indicate Linnaeus as the authority for species names is simply L.

Linnaean taxonomy

the work of Linnaeus represents the starting point of binomial nomenclature. In addition Linnaeus developed, during the great 18th century expansion of natural history knowledge, what became known as the Linnaean taxonomy; the system of scientific classification now widely used in the biological sciences.

Mankind

Within Homo sapiens he proposed five taxa of a lower (unnamed) rank. These categories were Africanus, Americanus, Asiaticus, Europeanus, and Monstrosus.

Human beings are Homo sapiens (see sapience). He also briefly described a second human species, Homo troglodytes ("cave-dwelling man").

Each race had certain characteristics that he considered endemic to individuals belonging to it. Native Americans were choleric, red, straightforward, eager and combative. Africans were phlegmatic, black, slow, relaxed and negligent. Asians were melancholic, yellow, inflexible, severe and avaricious. Europeans were sanguine and pale, muscular, swift, clever and inventive. The "monstrous" humans included such entities as the "agile and fainthearted" dwarf of the Alps, the Patagonian giant, and the monorchid Hottentot.^[19]

In addition, in Amoenitates academicae (1763), he defined Homo anthropomorpha as a catch-all term for a variety of human-like mythological creatures, including the troglodyte, satyr, hydra, and phoenix. He claimed that these creatures not only actually existed but were in reality inaccurate descriptions of real-world ape-like creatures.

Non placet, quod Hominem inter antropomorpha collocaverim, sed homo noscit se ipsum.

Not please (you) - Man among the Anthropomorpha^, but man learns to know himself.
