Deletion of Jean Calvignac

Comment: per . I am not seeing reliable secondary sources. It seems like he should be notable, considering his accomplishments, but the lack of reliable secondary sources stands out too much

Comment: per , not weak at all.  There are how many millions of patents out there?  (Heck, I've a deceased uncle who holds one.)  Being a patent owner even of a famous invention provides zero notability beyond that invention, failing reliable secondary sources about the subject.  Where are the sources about this fellow
