Anders Gustaf Ekeberg (16 January in Stockholm, Sweden – 11 February in Uppsala, Sweden) was a Swedish analytical chemist who discovered tantalum in [1][2][3][4] He was notably deaf.[5]

Education

Anders Gustav Ekeberg was a Swedish scientist, mathematician and expert in Greek literature.

His father, Joseph Erik Ekeberg, was a shipbuilder. His uncle was Carl Gustaf Ekeberg.[1]

Anders Gustav Ekeberg attended school at Kalmar, Söderåkra, Vestervik, and Karlskrona. He was a gifted student and enrolled at Uppsala University in , graduating in His thesis addressed the extraction of oils from seeds.[1] In and , he traveled and studied in Germany, hearing Martin Heinrich Klaproth lecture in Berlin as well as Christian Ehrenfried Weigel in Greifswald.[6]

Career

In , Anders Gustav Ekeberg began teaching at Uppsala.

He was a supporter of Antoine Lavoisier's proposals for systematizing chemical nomenclature. In he and Pehr von Afzelius published the first article to introduce the modern names for chemical elements such as hydrogen, nitrogen, and oxygen into the Swedish language,[1] "On the Present State of Chemical Sciences".[6]

He was made docent in chemistry in and experimentator (laborator) in , working as a demonstrator in the laboratory of Torbern Bergman.[7] In he lectured on the theory of combustion.

In , he was elected a member of the Royal Swedish Academy of Sciences.[1]

Ekeberg had poor health throughout his life. During his childhood a severe cold had impaired his hearing, which was further weakened over the years, so that it hindered his teaching activities. Subsequently, a gas explosion blinded him in one eye.[8]

Ekeberg was portrayed by his friends and students as a kind and gentle man.

He died, unmarried, at the age of [9]

Research

Ekeberg analyzed a number of the minerals found at Ytterby and Falun. In he analyzed specimens of tantalite from Kimito, Finland, and of yttrotantalite from Ytterby, Sweden. He is credited with finding the element tantalum in both.[1]

Ekeberg named the new element after the mythical Ancient Greek demigod Tantalus.

Anders Gustaf Ekeberg was born in in Sweden. He was a Swedish scientist, mathematician, and poet. He became a professor at Uppsala University in and initially made his name by developing advanced analytical techniques and by proposing Swedish names for the common chemical elements according to the principles set out by the "father of.

According to legend, he was condemned to eternal frustration when he had to stand in water up to his neck, but the water receded as he attempted to drink.[10]

The Anders Gustaf Ekeberg Tantalum Prize

In the Tantalum-Niobium International Study Center established The Anders Gustaf Ekeberg Tantalum Prize ("Ekeberg Prize"), an annual award to recognize excellence in tantalum research.

The Prize will increase awareness of the many unique properties of tantalum products and the applications in which they excel.[11] The inaugural winner of the Ekeberg Prize was Yuri Freeman, for his book "Tantalum and Niobium-Based Capacitors" (Springer, ).[12][13]

    Anders gustaf ekeberg biography of barack obama Barack Obama undoubtedly possesses one of the most complicated – and fascinating – backgrounds of any former president of the United States. Born to a father he hardly knew and to a mother he almost never saw, Obama’s path to the White House is one of the most remarkable and unlikely of any I’ve seen.
