Linnaeus

In 1758, Linnaeus wrote his Systema Naturae, in which he attempted to name all the species of the world in two names: Genus species

This is part of a larger zoological hierarchy: Kingdom, Phylum, Class, Order, Family, Genus, and species. You can recognize family names because the end in idae; you can recognize orders because they end in iformes.

A Kingdom is defined as a group of phyla that are more similar to each other than they are to any other group of phyla. A Phylum is defined as a group of Classes that are more similar to each other than they are to any other group of classes. And so forth....

Only the species is objectively defined: the only real object.
