I am one of many descendants.
I've put everything on their history at my website:
J. Wiss & Sons Co. - Scans of vintage books, pamphlets, catalogs, ads, etc.. Razors were eradicated from their history after they stopped making them. I was fortunate to come across these two catalogs. I also have a razor ad elsewhere at the site and an image of a razor ad not in my collection that isn't at the site.
