Can the original author of this piece please substantiate the claim that "Kroupa and her colleague Friedrich Hecht had discovered triple-weight hydrogen, also known as tritium?"

There is no citation for that sentence. The linked word "tritium" goes to the page that explains how in 1934, Rutherford et al. detected that apparently for the first time, and Harold Urey obtained deuterium in 1932 for which he received the Nobel Prize. If Franke and Kroupa discovered "triple-weight hydrogen" in 1930, and publicized the same, would this not be a notable historical fact that the Nobel committee would have recognized?

This article also has a block of text simply on "Triple-Weight Hydrogen" that is, indeed, a collection of articles on triple-weight hydrogen, but there is no connection between those pieces (listed in bullet points) and either Kroupa or Hecht.

Lastly, the only real information about Kroupa's apparently spectacular breakthrough discovery of tritium several years before others is the summary text for the Smithsonian Institution Archives' entry of the photograph of Kroupa used in the article (and cited as reference #7 as of the date of this comment). That doesn't work as a source, because, again, there's no information anywhere else that substantiates that claim.

And before someone suggests that Kroupa's contribution has been suppressed because she was a woman....the only indications for Friedrich Hecht are the ones that cite Kroupa as well.

Kroupa received a profile in Scientific American in November 1934: see "Personalities in Science," Scientific American 151:5 (November 1934): 227. This profile includes the photograph we see in this Wikipedia article, and the same information about Professor A. Franke and a rock from Winnipeg, Canada. It does not reference triple-weight hydrogen.

If left unchanged this article is going to inject a false narrative about the past and scientific discovery. 130.108.145.210 ( talk) 17:18, 10 April 2023 (UTC) reply
