  abstract  = {Humboldt unterschied zwischen drei Gebieten, die sich mit der Erfassung der Erde befassen: geognosia, historia telluris, physiografia. 1793 verwandte er den Begriff „Geognosie" zum ersten Mal. Er erl{\"a}uterte den Begriff in einer Fußnote, die 1815, 1817 und 1845 erneut abgedruckt wurde. Der Aufsatz untersucht die Bedeutung, die Humboldt dem Begriff „Geognosie" beilegte, und bietet eine neue deutsche {\"U}bersetzung der lateinischen Texte der Fußnote.},

  abstract  = {On the 17th of July 1800 Alexander von Humboldt was elected as an extraordinary member of the Prussian Acad{\´e}mie royale des sciences et belles-lettres at Berlin. The paper first deals with Humboldt's scientific activities before his election and then goes into detail as far as his integration into the work of the Academy is concerned. Humboldt was elected as a chimiste c{\´e}l{\`e}bre, but as a member of the Academy he did not work as a chemist. When Humboldt proposed in 1837 to classify the members of each class in special fields, he chose for himself the field of "mineralogy-geology".},
