medicine, geology, paleontology.

Baier was the son of Johann Wilhelm Baier, professor of Protestant theology at the University of jena, and Anna Katharine Musaeus After private tutoring he matriculated in 1693 at University of Jena, where he dutifully studied Philosophy, classical languages, mathematics, medicine, and natural science. During 1699 and 1700 he traveled in northern Germany and in the Baltic Sea provinces to Riga and Dorpat, enriching his knowledge by conversations with other Scholars and by examining collections and Visting libraries. In 1700 he finished his studies and war awarded the degrees of M.A., Ph.D., and M.D. After awarded educational trip, to visit mining facilities in the Hartz Mountains and university towns in northern Germany, he settled in 1701 as a practicing physician in Nuremberg.

In 1703, during the War of the Spanish Succession, Baier was director of a field hospital for the soldiers of the Nuremberg contingent. The following year the was awarded a professorship at the medical faculty of the University of Altdorf in Nuremberg which he held until his death. He was twice elected rector of the University in 1708 he became a member of the Leopoldina (Academy of Natural Scientists) and in 1730 was chosen its president.

Baier’s scientific fame today does not rest on his medical investigations, but on his studies of minerals and fossils. At that time the natural sciences could be pursued only within theframework of medicine: oryctography, comprising geology and palentology, was at the very beginning of its development Baier’s Orctogrphia norica(1708) was a new, systematic presentation based on his own studies. The work contributed much to disproving the idea that fossils were a mere sport of nature. By means of exact descriptions and good illustration for the he laid the foundations for the investigation of Jurassic fauna and of scientific paleontology in general. Instead of theory, he clearly presented what could be observed. He believed that the earth had been created in one act and that the Deluge was the only great change since the Creation. His exact foundation work, however, helped to prepare the ground for the next generation to determine historically the geological structure of mountains and to transform orctography in to geology
