Deletion of Duke Friedrich of Württemberg

Comment: per , , . A search of both English ''and German'' sources online show lots of media/press coverage of his tragic death and aftermath. He was also a very wealthy, active business man. It took only a few minutes to find literally hundreds of cites, and about an hour to add several sources, which reveal significant coverage in multiple (some reliable and some less so) sources. I added a few of those cites and I think this now passes the Heymann standard
Stance: keep
