Robert Whittaker

Robert Harding Whittaker (December 27, 1920 – October 20, 1980) was a distinguished American plant ecologist

In 1969 Whittaker proposed a "five kingdom" system in which three kingdoms were added to the animals and plants: Monera, Protista, and Fungi. Whittaker defined the kingdoms by a number of special characteristics.Whittaker, Robert H. (1969) "New concepts of kingdoms or organisms. Evolutionary relations are better represented by new classifications than by the traditional two kingdoms". Science, 163: 150-194Hagen, Joel B.
