Baltazar (Belsazar) Hacquet (1739–1815), francuski podróżnik, przyrodnik, geolog, profesor uniwersytetów we Lwowie i w Krakowie : nowe dane biograficzne w świetle niepublikowanych dokumentów z archiwów francuskich i niemieckich

Balthasar Hacquet, French physician and naturalist, Austrian army officer and inspector of mines in this country, has marked the history of natural science. Also as Professor of the Universities in Lviv and Cracow, he distinguished himself in many disciplines (botany, geology, anthropology and medicine), and particularly in the descriptions of the nature of the Carpathians and the Alps. This important person in the République des savants does not have the place in the contemporary historiography of science. His correspondence with French naturalists Georges Cuvier and Philippe-Isidore Picot de Lapeyrouse, as well as his autobiography and numerous documents, preserved in various archives, help to better understand his role in the development of natural sciences.
