Amazing. Sounds like a Krigler backstory with either 10 times the chutzpah or possibly even authenticity. Certainly a nice story.
If they do a YouTube video with real nerds, debunkable handwriting, formula books, etc., I might even grant them the "Grossmith exception". I do like real fragrance history - even the obscure raised to drama, like this. Stuffing the bottles in books to keep the pricey juice away from light-fingered Nazis - love it!
