Friedrich StromeyerFRS(For)FRSE (2 August 1776 – 18 August 1835) was a Germanchemist. He was the discoverer ofcadmium.

From 1982, the Friedrich Stromeyer Prize has been awarded for chemical achievement in Germany.^[1]

He was born inGöttingen on 2 August 1776^[2] the eldest son of Dr Ernerst Johann Friedrich Stromeyer, professor of medicine atGöttingen University, and his wife, Marie Magdalena Johanne von Blum.^[3]

Stromeyer studied Chemistry and Medicine at Göttingen andParis and received an MD degree from theUniversity of Göttingen in 1800, studying underJohann Friedrich Gmelin andLouis Nicolas Vauquelin. He was then a professor at the university, and also served as an inspector of apothecaries. His students includedRobert Bunsen.^[4]

In 1817, whilst studying compounds ofzinc carbonate, Stromeyer discovered the elementcadmium. Cadmium is a common impurity ofzinc compounds, though often found only in minute quantities. He was also the first to recommend starch as a reagent for freeiodine and he studied chemistry ofarsine andbismuthate salts.

In 1819, he was the first scientist to describe the mineraleudialyte.^[5]

In 1826, he was elected a Fellow of theRoyal Society of Edinburgh his proposer beingEdward Turner. As his fellowship was Ordinary (rather than Foreign or Honorary) this means he was physically present inEdinburgh at that time. The following year he was elected a Foreign Fellow of theRoyal Society of London.^[6]

In 1832, the mineralstromeyerite was named in his honour by mineralogistFrançois Sulpice Beudant.^[7]

He died in Göttingen on 18 August 1835, aged 59.
