Anders Gustaf Ekeberg
(16 January 1767 in
Stockholm
,
Sweden
? 11 February 1813 in
Uppsala
,
Sweden
) was a Swedish
analytical chemist
who discovered
tantalum
in 1802.

Education
[
edit
]
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
,
Soderakra
, Vestervik, and
Karlskrona
.
He was a gifted student and enrolled at
Uppsala University
in 1784, graduating in 1788. His thesis addressed the extraction of oils from seeds.
[1]
In 1789 and 1790, he traveled and studied in Germany, hearing
Martin Heinrich Klaproth
lecture in Berlin as well as
Christian Ehrenfried Weigel
in
Greifswald
.
[6]
Career
[
edit
]
In 1794, Anders Gustav Ekeberg began teaching at Uppsala. He was a supporter of
Antoine Lavoisier
's proposals for systematizing
chemical nomenclature
. In 1795 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 1794 and experimentator (
laborator
) in 1799, working as a demonstrator in the laboratory of
Torbern Bergman
.
[7]
In 1798 he lectured on the theory of combustion.
In 1799, 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 46.
[9]
Research
[
edit
]
Ekeberg analyzed a number of the minerals found at
Ytterby
and
Falun
. In 1802 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. 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.

The Anders Gustaf Ekeberg Tantalum Prize
[
edit
]
In 2018 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, 2018).
