Deletion of Kazimierz Cwojdziński

Comment: per my statement above. Yes, it's true that I didn't improve this article when I contested  deletion, but that was simply because I have other demands on my time, such as looking after my grandson, and thought that this was such an obvious notability pass that nobody would consider bringing the article to AfD without at least checking whether the available sources in Polish show notability
Stance: keep
