Stern–Gerlach Medal is one of many awards Wikidata knows about. Information is often available in a list within the articles. In some languages there are links to all those who received the award.
Having all the awards and all the people who received them in Wikidata is a massive undertaking. It can be argued that everyone who received an award has some notability..
Some people think that awards are not that important to categorise. Their way of thinking means that awards specifically relevant within a culture, a language become underrepresented. This is however an effect that diminishes in time.
It would be good when the lists were available to Wikipedias to use. When such lists become a service from Wikidata, it is easy to provide minimal information for the people that do not have an article yet. For best results it helps when all the associated labels are available.
