Johan Gotschalk Wallerius; (1709-1785) was a Swedish chemist, mineralogist & agriculturist.
Wallerius studied at the University of Uppsala, then taught medicine at Lund, before returning to Uppsala in 1735 as a lecturer in medicine. As a member of the medical faculty, he taught physiology and anatomy, but he also maintained an interest in chemistry and mineralogy. To pursue these subjects, Wallerius set up a chemical laboratory, where experiments were carried out and lectures on chemistry, mineralogy and assaying given. In 1750, Wallerius was appointed to the newly created professorship of chemistry at Uppsala. He remained in that position he served until failing health led to his retirement in 1767. ?In his professorship position, one of his duties was to be a moderator when students were to defend a dissertation.?We offer here four of those dissertations. As was the custom of that time, all are in Latin.
