It was Conrad Gessner (1516–1565), the forerunner of modern zoology, who emancipated natural sciences from a medieval deadlock and opened up new aspects of viewing natural objects through his own observations. He greatly inXuenced the German Xower painter Maria Sybilla Merian (1647–1717), who started to rear the insects she was painting herself to be able to observe them under natural conditions. When she exactly recognised the signiW- cance of the parasitoid is diYcult to assess, but in the preface of the 1717 version of her “caterpillar” book she made clear that she knew the whole cycle of parasitoid development. So the Wrst publication by a German, Merian, with a correct interpretation dates from 1717, although she might have discovered the phenomenon already 30 years earlier. Merian’s studies may have inspired Johann Leonhard Frisch (1666–1743) and August Johann Roesel von Rosenhof (1705–1759) to study insects in detail. Roesel von Rosenhof accurately described several behavioural aspects related to the life history of parasitoids. The Wrst taxonomists working speciWcally on Hymenopteran parasitoids in Germany were Johann Ludwig Christian Gravenhorst (1777–1857) and Christian Godfried Nees von Esenbeck (1776–1856). The forestry entomologist Julius Theodor Christian Ratzeburg (1801–1871) was the Wrst to describe the ecological relationships of parasitoids in detail. He inXuenced many other entomologists in the 19th century and founded the long tradition of Hymenopteran parasitoid research in Germany10aforest entomology10aGermany10ahistory of insect parasitism10aHymenoptera10aparasitoids10ataxonomy1 aVidal, S.  uhttps://insectafgseag.myspecies.info/en/content/history-hymenopteran-parasitoid-research-germany
