Lavoisier

1787 · 173027 — Paris: Chez Cuchet 1787. Modern chemistry therefore starts in 1787 First edition second issue of the work which introduced modern chemical terminology among the most fundamental scientific texts of the 18th century. The folding tables outline the first taxonomic system of chemical substances arranged according to their composition a system which proved immediately influential; even established figures like Priestley felt obliged to adopt the new terminology. The late 18th century witnessed considerable debates over the theory and practice of chemistry. The chief theoretical shift was the identification of oxygen in place of the hypothesized phlogiston which led many contemporaries to view the existing chemical terminology as outdated and confused. This move was largely driven by Lavoisier 1743-1791 and his fellow authors of the Méthode Louis Bernard Guyton de Morveau 1737-1816 Claude-Louis Berthollet 1748-1822 and Antoine-François de Fourcroy 1755-1809. In the Méthode they develop a systematic nomenclature largely derived from oxygen theory arguing that chemical substances should be named according to their constituents. Simple substances should receive simple names and compounds should receive complex names deriving from their constituents. "The new terms were soon translated and adapted into other languages and became the basis of the modern nomenclature of inorganic chemistry. In the purely pragmatic terms of the terminology used modern chemistry therefore starts in 1787" Crosland p. 411.
