Ernst Haeckel: Biography, Facts and Career

Ernst Heinrich Philipp August Haeckel (; German: [ɛʁnst ˈhɛkl̩]; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ecology, phylum, phylogeny, ontogeny, and Protista. Haeckel promoted and popularised Charles Darwin's work in Germany and developed the disproven but influential recapitulation theory ("ontogeny recapitulates phylogeny"), later generalizing it into the so called "Biogenetic Law". He wrongly claimed that an individual organism's biological development, or ontogeny, parallels and summarizes its species' evolutionary development, or phylogeny, using incorrectly drawn images of human embryonic development to derive the law. Whether they were intentionally falsified, or drawn poorly by accident is a matter of debate. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his Kunstformen der Natur ("Art Forms in Nature"), a book which would go on to influence the Art Nouveau artistic movement. As a philosopher, Ernst Haeckel wrote Die Welträthsel (1895–1899; in English: The Riddles of the Universe, 1900), the genesis for the term "world riddle" (Welträtsel); and Freedom in Science and Teaching to support teaching evolution. He also coined the "Biogenetic Law". Haeckel promoted scientific racism and embraced the idea of Social Darwinism. He was the first person to characterize the Great War as the "first" World War, which he did as early as 1914.
