FeatureIda Noddack and the missing elements
Distinguished women chemists were rare in the early 20th century, but their contributions to chemistry are of great significance. Ida Noddack's scientific career centred around her intensive study of the Periodic Table, and resulted in her discovery, with husband Walter Noddack and physicist Otto Berg, of the metal rhenium, and of nuclear fission in the search for element 93.
