Stromeyer, Friedrich. 1808. Gnmdriss der theoretischen Chemie. 2 vols. Gottingen Johann Friedrich Rower. 

Friedrich Stromeyer (1776-1835). During the inspection of a pharmacy, Stromeyer confiscated zinc carbonate as it did not meet the purity standards when calcined, it showed a yellow residue cadmium oxide. 

In Germany, Liebig s well-known laboratory at Giessen was preceded by several other chemical laboratories, notably, those of Friedrich Stromeyer at Gottingen and Johann Dobereiner at Jena. 86 It is striking, as Russell McCormmach has noted, that in Germany and elsewhere the first directors of laboratories in experimental physics tended to be men trained in chemistry. 87... 

Cadmium - the atomic number is 48 and the ehemical symbol is Cd. The name derives from the Greek kadmeia for calamine (zinc carbonate) with which it was found as an impurity in nature. Kadmeia was also the name of the fortress of Thebes, a city in the Boeottia region of central Greece. The fortress was named after its founder, Cadmus, who was the son of the Phoenician king, Agenor, and brother of Europ and would be a possible source for the name of the ore. The element was discovered and first isolated by the German physician Friedrich Stromeyer in 1817. 

Friedrich Stromeyer, 1776-1835. German physician, botanist, chemist, and pharmacist. Inspector-general of all the Hanoverian apothecary shops. Discoverer of the element cadmium. His collection of thirty mineral analyses is a classic of analytical chemistry.

Robert Bunsen was the son of a professor of modem languages at Gottingen, and was bom in that city on March 3.1, 1811. After attending the academy at Holzminden he entered the University of Gottingen, and studied chemistry under Professor Friedrich Stromeyer. At the age of twenty years he received his degree of doctor of philosophy. This does not mean that Bunsen was precocious, for, as Wilhelm Ostwald explains, students graduated at a much earlier age then than they do now. 

In 1814 Jean-Jacques Colin and Henri-Frangois Gaultier de Claubry, professor of toxicology at the School of Pharmacy in Paris, described the blue substance produced when free iodine acts on starch, and studied the effects of temperature and of sulfurous acid, hydrogen sulfide, and other reagents on this reaction (131). In the same year Friedrich Stromeyer first applied this starch reaction to analytical chemistry and was able to detect as little as one part of iodine in 350,000 to 450,000 parts... 

Birth of Friedrich Stromeyer, the discoverer of cadmium, at Gottingen. 

Cadmium is a transition metal. The transition metals are the elements found in Rows 4 through 7 between Groups 2 and 13 in the periodic table, a chart that shows how elements are related to each other. Cadmium was discovered by German chemist Friedrich Stromeyer (1776-1835) in 1817. It is found most commonly in ores of zinc.

Another excellent quantitative worker, who also (like Klaproth) made many analyses of minerals, was Friedrich Stromeyer (Gottingen 2 August 1776-18 August 1835), a pupil of Vauquelin who first studied botany. He became professor of chemistry in Gottingen in 1810. He wrote books on chemistry and published a number of important investigations. He showed that aragonite is a definite crystalline form of calcium carbonate and is not necessarily contaminated with strontium, and recommended starch as a reagent for free... 

Discovery Cadmium was discovered by Friedrich Stromeyer in Gottingen, Germany. He found the new element in 1817 when he examined an impure zinc carbonate, ZnCO. ... 

Germany at that time consisted of a number of independent states. Gottingen was situated in Hannover. The authorities of the state considered it important to inspect the pharmacies, and Friedrich Stromeyer was in 1816 designated to supervisor. The duty was combined with the professorship at the university. 

Cadmium compounds were first used as colorants shortly after the yellow compound cadmium sulfide was discovered by the German metallurgist Friedrich Stromeyer. The element cadmium was discovered by several chemists in 1817. Stromeyer was however the first to report it and is credited with its discovery. He recommended that the brightly colored yellow sulfide be used as an artists color.
