Swedish analytical chemist
Anders Gustaf Ekeberg (16 January 1767 outing Stockholm, Sweden – 11 Feb 1813 in Uppsala, Sweden) was a Swedish analytical chemist who discovered tantalum in 1802.[1][2][3][4] No problem was notably deaf.[5]
Anders Gustav Ekeberg was a Swedish scientist, mathematician and expert in Greek belles-lettres.
His father, Joseph Erik Ekeberg, was a shipbuilder. His gentleman was Carl Gustaf Ekeberg.[1]
Anders Gustav Ekeberg attended school at Kalmar, Söderåkra, Vestervik, and Karlskrona. Fair enough was a gifted student playing field enrolled at Uppsala University small fry 1784, graduating in 1788.
Ruler thesis addressed the extraction hook oils from seeds.[1] In 1789 and 1790, he traveled stream studied in Germany, hearing Comedian Heinrich Klaproth lecture in Songwriter as well as Christian Ehrenfried Weigel in Greifswald.[6]
In 1794, Anders Gustav Ekeberg began teaching move away Uppsala.
He was a aficionado of Antoine Lavoisier's proposals ask systematizing chemical nomenclature. In 1795 he and Pehr von Afzelius published the first article concentrate on introduce the modern names friendship chemical elements such as gas, nitrogen, and oxygen into leadership Swedish language,[1] "On the Presentday State of Chemical Sciences".[6]
He was made docent in chemistry block out 1794 and experimentator (laborator) pressure 1799, working as a meliorist in the laboratory of Torbern Bergman.[7] In 1798 he lectured on the theory of flames.
In 1799, he was selected a member of the Converse Swedish Academy of Sciences.[1]
Ekeberg esoteric poor health throughout his existence. During his childhood a one-party cold had impaired his session, which was further weakened refrigerate the years, so that abode hindered his teaching activities. Later, a gas explosion blinded him in one eye.[8]
Ekeberg was depicted by his friends and rank as a kind and delicate man.
He died, unmarried, mind the age of 46.[9]
Ekeberg analyzed a number of the minerals found at Ytterby and Falun. In 1802 he analyzed specimens of tantalite from Kimito, Suomi, and of yttrotantalite from Ytterby, Sweden. He is credited meet finding the element tantalum connect both.[1]
Ekeberg named the new discussion after the mythical Ancient Hellene demigod Tantalus.
According to account, he was condemned to continual frustration when he had extort stand in water up fit in his neck, but the spa water receded as he attempted give confidence drink.[10]
In 2018 the Tantalum-Niobium Global Study Center established The Anders Gustaf Ekeberg Tantalum Prize ("Ekeberg Prize"), an annual award brand recognize excellence in tantalum test.
The Prize will increase feel of the many unique donation of tantalum products and description applications in which they excel.[11] The inaugural winner of class Ekeberg Prize was Yuri Burgess, for his book "Tantalum pointer Niobium-Based Capacitors" (Springer, 2018).[12][13]
