Torbern Olof Bergman (KVO) (20 March 1735 – 8 July 1784) was a Swedish chemist and mineralogist noted for his 1775 Dissertation on Elective Attractions, containing the largest chemical affinity tables ever published.

Bergman lectured at the University of Uppsala on physics and mathematics, publishing papers on the rainbow, the aurora, the pyroelectric phenomena of tourmaline.

To refute them, he shut himself up for some time in a laboratory, and prepared a treatise on the manufacture of alum, which became a standard work.

Thanks to the influence of Gustav III, then crown prince and chancellor of the university, he was appointed a professor of chemistry, and remained at this position for the rest of his life.

[1] Bergman greatly contributed to the advancement of quantitative analysis, and he developed a mineral classification scheme based on chemical characteristics and appearance.
