Wikipedia summary
Axel Fredrik Cronstedt
Baron Axel Fredrik Cronstedt () was a Swedish mineralogist and chemist who discovered the element nickel in 1751 as a mining expert with the Bureau of Mines. Cronstedt is considered a founder of modern mineralogy, for introducing the blowpipe as a tool for mineralogists, and for proposing that the mineral kingdom be organized on the basis of chemical analysis in his book @i@Försök till Mineralogiens eller mineral-Rikets upställing ("An attempt at mineralogy or arrangement of the Mineral Kingdom", 1758).
Georg Brandt
Georg Brandt (26 June 1694 - 29 April 1768) was a Swedish chemist and mineralogist who discovered cobalt (c. 1735). He was the first person to discover a metal unknown in ancient times.
Jean-Charles-Galinard de Marignac
Jean Charles Galissard de Marignac (24 April 1817 - 15 April 1894) was a Swiss chemist whose work with atomic weights suggested the possibility of isotopes and the packing fraction of nuclei. His study of the rare earth elements led to his discovery of ytterbium in 1878 and co-discovery of gadolinium in 1880.
