Huguette Clark, “antisocial socialite”.
I recommend clicking through and reading the entire NYT obit. Ms. Clark was 104 when she died, and her story is one of the saddest things I’ve read recently.
In addition to the Astor comparison, I’m reminded somewhat of the Green family, particularly Sylvia Green.
On a totally unrelated note, I think I’m going to have to pre-order the Blu-Ray edition of Citizen Kane
(Hattip: I actually saw the obit skimming over the NYT site this morning, but thanks to Althouse for providing the link.)
