Scheffer, Henrik

On his way home from the Netherlands he studied mining and metallurgy in the Harz, and in 1727 he was placed in charged of the chemical laboratory at the Bureau of Mines in Stockholm, which was then in poor financial condition. After the laboratory was sold, Brandt and his students Henrik Teofil Scheffer and Axel Fredrik Cronstedt carried on their epoch-making researches at the Royal Mint, and in 1730 Brandt became assay master of the Mint. Three years later he published a systematic investigation of arsenic and its compounds in which he showed that arsenic is a semi-metal and that white arsenic [arsenious oxide] is its calx (35). 

Henrik Theophilus Scheffer (Stockholm 29 December 1710-10 August 1759), an assayer and technical chemist in Stockholm, gave courses of lectures published by Bergman from notes taken in 1749-50-51 by Jonas Alstromer (1685-1761), a Stockholm merchant, with important additions by Bergman ... 

In the middle of the 18 century, the Laboratorium Chymicum in Stockholm (see Chapter 30 Cobalt) was an institution with a worldwide reputation. When the platinum question came up in Europe it was natural that the eyes of European chemists were directed towards Stockholm. It was Henrik Scheffer who was assigned to examine the new metal. 

Henrik Scheffer (1710-1759) studied mathematics in Uppsala with Anders Celsius and chemistry under Georg Brandt at the Laboratorium Chymicum.
