A new biography came out on Karl Lagerfeld that incidentally supports our rectification despite that it follows the official line of 1933. See the original post here. Another quirk is Lagerfeld gives the same ascendant as Madame Chanel: Sagittarius.
BTW, if it didn’t work, I would re-rectify Lagerfeld’s chart. I have done that a few times (see Bill Barr, former US Attorney general) as as rectifying living or recently dead people is always problematic because the information on them is either sketchy, or wrong.
