Works
Haekel was professor of comparative anatomy at the University of Jena, where he worked for 47 years, from 1862 to 1909. Haekel discovered, described and named thousands of new species, mapped a tree of life relating all life forms.Ernst Haeckel 1868. The history of creation, translated by E. Ray Lankester, Kegan Paul, Trench, London, 1883, 3rd edition, volume 1. He coined many terms in biology, including ecology, phylum, phylogeny,  stem cell, and the kingdom Protista. Haeckel promoted and popularised Charles Darwin's work in Germany and developed the controversial recapitulation theory ("ontogeny recapitulates phylogeny"). This claimed that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development.Di Gregorio, Mario A. 2005.

The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures.Haeckel, Ernst. Art forms from the ocean: the Radiolarian atlas of 1862. Prestel Verlag, 2005.  As a philosopher, Ernst Haeckel wrote Die Welträtsel (1895–1899, The Riddle of the Universe, 1901), and Freedom in Science and Teaching to support teaching evolution.Freedom in science and teaching. German 1877, English 1879, .

Haeckel was a member of the nationalist and antisemitic Pan-German League (German: Altdeutscher Verband) and of the peace organization Verband für internationale Verständigung.
