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 ...

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

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 ...
