That name is used, online, by - among others - VIAF, ISNI, BNF, Nukat, Worldcat, the International Atomic Energy Agency and the award page previously discussed.
> I acted accordingly and removed the other last name. As can be seen in Dr Lemaire's papers, she has consistently used the name "Marie-Claude Lemaire" and there is no reason not to respect that request.
That is clearly not so. See, for example:
I'm sympathetic to Dr Lemaire for whatever demons trouble her, but bowdlerising Wikidata and thereby reducing its usefulness will not resolve them.
