In chemistry, Jacob Spielmann (1722-1783) was a French chemist, professor of chemistry at Strasbourg University from 1749 to circa 1780, notable for being German polymath Johann Goethe’s chemistry teacher in 1770-71.  Spielmann was one of the last French chemists who supported the phlogiston theory.  Spielmann could have been the role model for the Captain in Goethe's human affinity table.
Spielmann was a student of phlogiston era chemists, Germans Johann Pott (1692-1777), Andreas Marggraff (1709-1782), and Johann Henckel (1678-1744), and most notably French chemist and affinity table creator Étienne Geoffroy (1672-1731).
