The Beginning of a Long Series of Scientific Blunders The enthusiasm that oft en characterizes researchers can at times distort certain preconceived convictions and deceive the scientist into believing that a controlled experiment has produced the correct result when, in fact, it is erroneous due to insufficient or incorrect data. This is the case for the discovery of a mysterious terra nobilis made by the chemist Torbern Olof Bergman. Bergman was born on March 20, 1735, in Katrineberg, Sweden. He was a chemist and mineralogist who became famous in 1775 for printing the most extensive tables of chemical affinity ever published at that time, and he was the first chemist to use letters of the alphabet as a notation system for chemical species. He took his doctorate at the University of Uppsala in 1758. After initially holding the professorship of physics and mathematics, he later took the chair in chemistry, which he retained for the rest of his life. Bergman made significant contributions to progress in quantitative analysis and metallurgy, and he developed a classification scheme of minerals based on their chemical characteristics. In 1777, Bergman confidently announced the result of an extremely expensive investigation. He studied the behavior of diamond with a blowpipe, and, aside from the presence of silicon, he seemed to have generated an unknown compound. He extracted the oxide of a metal from the diamonds, which, according to the custom of the time, he called terra nobilis. His discovery was quickly forgotten, not least because his life soon took a tragic turn. After marrying Margareta Catharina Trast in 1771, he enthusiastically continued his activities as a synthetic and analytical chemist, 3 but on July 8, 1784, at the age of only 49, he died in Medevi, Sweden. It is believed that he fell victim to poisoning from the chemical substances he used in his research. At the time of his death, he had been a member of the Royal Society of London and the Swedish Royal Academy for many years, and he was certainly one of the most famous chemists of his time.
