Friedrich Gabriel Sulzer
Friedrich Gabriel Sulzer (10 October 1749 – 14 December 1830) was a German physician from Gotha, Thuringia. Sulzer had a large collection of minerals and published also new results from new species. In 1791, Sulzer published together with Johann Friedrich Blumenbach their results on a new mineral he had acquired. He named the mineral strontianite (strontium carbonate) and made clear that it was distinct from the witherite (barium carbonate) and stated that it contained a new element. He was head of a veterinary school and a midwifery school and chief physician for the local spa in Ronneburg, Thuringia . Additionally, he was the physician for Dorothea von Medem and her sister Elisa von der Recke. He was part of the "Musenhof der Herzogin von Kurland". In 1774, Sulzer, a companion of Johann Wolfgang von Goethe, devoted a whole academic monography in the domain of social sciences and natural history to hamsters, entitled "An approach to a natural history of the hamster" (""Versuch einer Naturgeschichte des Hamsters""). In several instances, he used the hamster to document the equal rights of all beings, including "Homo sapiens".
