Prematurity in Scientific Discovery: On Resistance and Neglect
The Italian discovery eventually led to a change in the periodic table: the term “
masurium” and its symbol Ma were displaced by “technetium” (reflecting its
creation by technology) and the symbol Tc.38 The work on rhenium was well
accepted ...

which they named masurium, and element 75, rhenium. Their initial identification
of both elements was based in part on x-ray spectroscopic data that were difficult

A Mind Always in Motion: The Autobiography of Emilio Segrè
In the same paper they had announced the discovery of two elements: element

Bureau of Standards Journal of Research
After many years of fruitless search by an unknown number of investigators, the
problem was attacked by Walter Noddack and Ida Tacke, who announced,1 in
1925, the discovery of both 43 and 75, and proposed the names "masurium" and

The Chemical Tree: A History of Chemistry
They again used Moseley's X-ray spectroscopy to identify and to measure lines,
and identified what they named rhenium (75) after Tacke's birthplace on the
Rhine, and 'masurium' after Noddack's homeland in East Prussia. Whereas
rhenium ...
