Abstract: | This year marks the bicentenary of the death of the Swedish chemist Torbern Bergman. He took up chemical work comparatively late in life, but made important contributions to the classification and analysis of minerals and mineral waters. He is best known, however, for his work on chemical affinity, described in his Dissertation on Elective Attractions (1775). He corresponded with contemporary French chemists, including P. J. Macquer, the bicentenary of whose death also falls this year. |
