Step-by-step explanation:
Carl Linnaeus, a Swedish botanist, made significant contributions to the field of classification. He developed the Linnaean classification system in the 1700s, which formed the basis of all modern classification systems. Linnaeus grouped organisms based on their physical traits, such as the number of legs or shape of leaves. His method of naming species, called binomial nomenclature, gave each species a unique two-word Latin name consisting of the genus and species name. Linnaeus is known as the 'father of taxonomy' for his pioneering work in organizing and naming living things.
