Ernst Haeckel was born on 16 February 1834, in Potsdam (then part of the Kingdom of Prussia ). In 1852 Haeckel completed studies at the Domgymnasium, the cathedral high-school of Merseburg. He then studied medicine in Berlin and Würzburg, particularly with Albert von Kölliker, Franz Leydig, Rudolf Virchow (with whom he later worked briefly as ...
May 03, 2014 · Ernst Haeckel's Biogenetic Law (1866) The biogenetic law is a theory of development and evolution proposed by Ernst Haeckel in Germany in the 1860s. It is one of several recapitulation theories, which posit that the stages of development for an animal embryo are the same as other animals' adult stages or forms.
Aug 03, 2019 · Born in Germany in 1834, Ernst Haeckel studied medicine at the University of Berlin and graduated in 1857. While he was a student, his professor Johannes Müller, took him on a summer field trip to observe small sea creatures off the coast of Heligoland in the North Sea, sparking his life-long fascination for natural forms and biology.

Ernst Heinrich Philipp August Haeckel (February 16, 1834 1919) was a philosopher, professor, physician, naturalist, biologist and artist.
Ernst Heinrich Philipp August Haeckel was born on 16th February 1834 in Potsdam, Germany. He spent his childhood in the German town of Merseburg where his father worked as a government official.
After receiving a degree in medicine in 1857, Haeckel practiced medicine for a short time. He then travelled to Italy where he painted and considered becoming a professional artist.
Heavily influenced by Charles Darwins 1959 work On the Origin of Species by Means of Natural Selection Haeckel returned to academic studies, obtaining a doctorate in zoology from the University of Jena in 1862 and then teaching zoology there. He became an associate professor of zoology in 1862 and Haeckel remained at Jena until he retired from teaching in 1909.
Although best known for the famous statement ontogeny recapitulates phylogeny, he also invented many words commonly used by biologists today, such as phylum, phylogeny, and ecology. On the other hand, Haeckel also stated that politics is applied biology, a quote used by Nazi propagandists. The Nazi party, rather unfortunately, used not only Haeckels quotes, but also Haeckels justifications for racism, nationalism and social Darwinism.
Haeckel also proposed the idea that all multicellular animals derived from a theoretical two-layered (ectoderm and endoderm) animal, the Gastraea, a theory that provoked much discussion. He engaged in much valuable research on marine invertebrates, such as the radiolarians, jellyfish, calcareous sponges, and medusae, and wrote a series of monographs on these groups based largely on specimens brought back by the Challenger Expedition of 1872 to 1876.
He was the first to divide the animal kingdom into unicellular and multicellular animals. An ardent Darwinist, Haeckel made several zoological expeditions and founded the Phyletic Museum at Jena and the Ernst Haeckel Haus, which contains his books, records, and other effects. An effective popularizer of science, Haeckel produced numerous tree diagrams, showing evolutionary relationships between different species. Modern scientists and science historians have varied on the value of these diagrams but many praised his work and creativity. Haeckel also produced artwork, much of it quite beautiful, starting with his atlas of radiolarians, published in 1862.
It has been argued that what he saw was influenced by Jugendstil, the Art Nouveau form popular in Germany at the time. Whether or not artistic style influenced Haeckels illustrations, his illustrations certainly influenced later art forms, including light fixtures, jewelry, furniture, and even a gateway to the Paris Word Fair in 1900. In 1906 the Monist League was formed at Jena with Haeckel as its president. The League held a strong commitment to social Darwinism in which man was seen as part of nature and in no way qualitatively distinct from any other organic form.
The European War became known as The Great War, and it was not until 1931, with the beginning realization that another global war might be possible, that there is any other recorded use of the term First World War.
Although Haeckels ideas are important to the history of evolutionary theory; he was a competent invertebrate anatomist most famous for his work, many speculative concepts that he championed are now considered incorrect but still he has been admired greatly for his contributions.
Haeckel died on August 9th, 1919, in Germany, leaving behind his great inventions for others to serve as a source of inspiration.

Apr 05, 2021 · Ernst Haeckel and the Origins of Ecology. Ecology derives from the Greek word oikos, meaning "household," and is the study of the relationships among organisms and their surroundings. The science was named by German biologist Ernst Haeckel (1834-1919), who introduced the term in several works in the 1860s and 1870s, first in German and then in ...
