Abstract

On the basis of the „principle of the universal connection“ Leibniz connected the science of nature, anthropology and meteorology and linked climatic conditions with human diseases. In 1671/76 he put his bioclimarical conception in writing for the first time in the Directiones. Stimulated and supported by Caspar Neumann, Bernardo Ramazzini and Friedrich Hoffmann, Leibniz since 1690 demanded in several letters and papers bioclimatic observations for Germany. The Summariscbe Punctation is the best paper, where Leibniz named the conditions for an effective bioclimatology. The present paper reports on the philosophical basis and the chronological sequence of Leibniz' bioclimatical project
