Carolus Linnaeus
He developed a system of classification that divided all living things into several groups, including Kingdom, Phylum, Class, Order, Family, Genus, and Species. He also devised the modern system of scientific names, which is still in use today. Linnaeus published his classification system in his book "Systema Naturae" in 1735, which established the framework for the modern taxonomy system. He also published many other books describing and classifying thousands of plants and animals.
