Cerium (Ce, [Xe]4/ 15t/ 6.v2), name and symbol after the asteroid Ceres. Discovered (1803) by Jons Jacob Berzelius and Wilhelm Hisinger and independently by Martin Klaproth. 

Selenium was discovered in the early 1800s by Jons Jakob Berzehus (1779—1848) along with a friend Wilhelm Hisinger (1766—1852), who was a mineralogist. Berzehus believed tellurium was contaminating the product in a sulfuric acid factory. Later, he found it to be another element similar to tellurium. After isolating it, he identified it as element 34, which turned out to be selenium.

In the autumn of 1824 Arfwedson helped Berzelius and Wilhelm Hisinger arrange the mineral collection of the Academy of Sciences according to Berzelius chemical system. Two years later Berzelius visited Arfwedson at Hedenso. This, said he, is a most beautiful place, and Arfwedson and his wife have improved it since I was here last time. Inside there reigns extreme neatness and a degree of luxury which could be much less and still be sufficient (3). Berzelius pleasure was marred, however, by an attack of gout which did not yield even when Arfwedson himself applied nine leeches to the affected knee. 

Wilhelm Hising, or Hisinger, as he was called after being raised to... 

Skinnskatteberg, Vestmanland, Sweden, where Wilhelm Hisinger once lived. The mineral cente was first found m one of the mines on his estate. 

Wilhelm Hisinger, 1766-1852. Swedish mineralogist and geologist. Owner of the famous Riddarhytta mining property in Vestmanland, where cerite was discovered. He was one of the first to analyze the lithium mineral petalite. 

Ekeberg (40, 41), M. H Klaproth, and N.-L Vauquelin all investigated Gadolin s new oxide, and it came to be called ijttria, a name derived from Ytterby. In 1803 Klaproth discovered in the mineral cerite another earth which he called terre ochroitebut which is now known as ceria. Berzelius and Wilhelm Hisinger also discovered ceria independently, but upon further investigation neither their yttria nor their ceria proved to be a pure oxide (3). 

Birth of Wilhelm Hisinger, the discoverer of the earth ceria. Berzelius, Hisinger, and Klaproth all investigated this earth, the latter independently. 

Swedish chemists Jons Jakob Berzelius and Wilhelm Hisinger and German chemist Martin Klaproth discover the black rock of Bastnas, Sweden, which led to the discovery of several elements. Berzelius and Hisinger originally assume the rock is a new element, which they name cerium. 

In 1789, Klaproth isolated zirconia from zircon, and in the same year he discovered uranium in the ore pitchblende. He confirmed the existence of strontia (discovered by Thomas Charles Hope [1766-1844]) in 1795 and discovered titanium that same year. In 1797, he isolated chromium, while in 1789 he announced the discovery of tellurium. Klaproth shares a three-way discovery of cerium with Wilhelm Hisinger (1766-1852) and Jons Jakob Berzelius (1779-1848). 

In 1751 the Swedish chemist Axel F. Cronstedt found, near Bastnas, Sweden, a mineral that was eventually named cerita (its name related to the planetoid Ceres). Independently, Martin Klaproth, Jons J. Berzelius, and Wilhelm Hisinger, working with cerita, each isolated a product, ceria (in 1803), from which Carl G. Mosander obtained three different substances, as oxides cerium, lanthanum, and a mixture of oxides known as didymia. 

Berzelius (Figure 6.4) studied medicine, but even as a student he was performing chemical experiments in his spare time. After graduation he worked as a physician to the poor in several areas of Stockholm at a very low salary, but continued his chemical investigations in conjunction with Wilhelm HIsInger (1766-1852). They performed important work on the chemical effects of an electric current (Chapter 7). In 1807 Berzelius was appointed professor of medicine and pharmacy at Stockholm, and following a reorganisation in 1810 he became professor of chemistry and pharmacy. 

Davy s move to the Royal Institution meant that he had to abandon his electrochemical researches for a while. In 1803 Berzelius and Wilhelm Hisinger (1766-1852) found that when an electric current was passed through solutions of various salts, acids were found at the positive pole and bases at the negative. This observation was probably important in leading Berzelius to the dualistic theory (see below).
