Ernst Haeckel was a renowned German biologist, naturalist, physician, philosopher and artist who identified many new species of living beings and gave names to thousands of them. He traced a genealogical tree of all life forms and came up with new terms in biology such as phylogeny, anthropogeny, the kingdom Protista, phylum, stem cell, and ecology. He publicized Darwin’s theory by producing his work in German language. He presented his recapitulation theory- ‘ontogeny recapitulates phylogeny’ in German, which became controversial subject during his time. Haeckel was also the first to regard psychology as a branch of physiology. Although he contributed much to the theory of evolution, he was best remembered for his extensive work on radiolarian. Haeckel’s book ‘Die systematische Phylogenie’ or ‘Systematic Phylogeny’ which he published in 1894 was regarded as his best work. In 1907, Haeckel was honored with the title of Excellency by Kaiser Wilhelm II; and in 1908, he was awarded the Darwin-Wallace Medal by the Linnean Society of London. Apart from his research activities, Haeckel had also gained the reputation of being a great patron of art. The illustrations in his books spoke volumes of his creativity and his inclination towards paintings.
