Life and work

Driesch attended from 1877 to 1886 the scholars of the school Johanneums in Hamburg. He studied from 1886 at the University of Freiburg in August Weismann, from 1887 at the University of Jena Zoology at Ernst Haeckel and Oscar Hertwig and botany at Ernst Stahl. In 1889, he remained at the newly established marine biological station on Plymouth to studies. In 1889 he received his doctorate in Haeckel with his work " Tectonic Studies in hydroid ". In 1890, he went on study trips to India and Lesina. In 1891 he was at the Zoological Station of Naples, where he made experimental studies on the development of mechanical sea urchin germ and he succeeded by " batch experiments " the separation of the first blastomeres. Their advancement to all individuals, regardless of whether it eg a sea urchin embryo in the middle abschnürte ( whereupon two sea urchins emerged ), or two embryos put together at an early stage of development and it emerged a whole sea urchins, indicated his opinion on the existence of a fundamental biological " force ," which he borrowed Aristotels, as entelechy, a living beings inherent ability themselves to complete as a living being, described. Thus he became a central representative of the neovitalists and especially natural philosophical works in the 1920s found widespread both among the laity and among biologists and zoologists.

From 1900 he was a private tutor in Heidelberg, in 1904, he was elected a member of the Leopoldina. In 1907 he became professor of Natural Theology in Aberdeen ( Scotland).

From 1924 he was also involved in parapsychology, served 1926-27 as president of the Society for Psychical Research in 1932 and published a methodology for this area (often reprinted, with contributions by Hans Bender Paperback ).
