unicellular organism
among the pioneers in the study of the protists, which were almost ignored by linnaeus except for some genera (e.g., "vorticella, chaos, volvox, corallina, conferva, ulva, chara, fucus") were leeuwenhoek, o. f. müller, c. g. ehrenberg and félix dujardin. the first groups used to classify microscopic organism were the animalcules and the infusoria. in 1818, the german naturalist georg august goldfuss introduced the word "protozoa" to refer to organisms such as ciliates and corals. after the cell theory of schwann and schleiden (1838–39), this group was modified in 1848 by carl von siebold to include only animal-like unicellular organisms, such as foraminifera and amoebae. the formal taxonomic category "protoctista" was first proposed in the early 1860s by john hogg, who argued that the protists should include what he saw as primitive unicellular forms of both plants and animals. he defined the protoctista as a "fourth kingdom of nature", in addition to the then-traditional kingdoms of plants, animals and minerals. the kingdom of minerals was later removed from taxonomy in 1866 by ernst haeckel, leaving plants, animals, and the protists ("protista"), defined as a “kingdom of primitive forms”.
