Life

Qvist grew up in Åmot, Gästrikland . He studied at Uppsala University from 1743 and was an auscultant at the Bergskollegium in Stockholm from 1747. There he was a friend and colleague of Sven Rinman . In 1770 he was appointed miner and from 1771 he was busy building a steelworks near Stockholm based on English models, which began operations in 1776 (but there were further delays, as material for robust crucibles had to be developed or procured). Qvist had previously traveled to England in 1766/67 and studied iron and steel production there, about which he published a report. He took a two-year leave of absence from the Bergskollegium to build the steelworks. In 1782 he was promoted to assessor at the Bergskollegium. Together with his brother-in-law, the pharmacist Frans Joachim von Aken, he was looking for coal for the blast furnaces in Sweden and was still looking for suitable material for chamotte bricks.

He played a role in the discovery of molybdenum . This occurred in nature in the form of molybdenum luster and was often confused with lead luster (galena) or graphite. Qvist proved in 1754 that molybdenum luster did not contain lead. Molybdenum was first represented and recognized as an element in 1778 by Carl Wilhelm Scheele .

In 1769 he became a member of the Royal Swedish Academy of Sciences.

He is not to be confused with Bengt Bengtsson Qvist, a cousin who was active in the Finnish iron industry.
