The book Empty Mansions [1] is about the heiress of Montana copper mining interests, Hugette Clark (father is namesake of Nevadah's county). IIRC, she inherited multiple properties and $300m+USD. A quite fascinating view into the insanity of an eccentric ultrawealthy, who lived into the 21st Century at times thread-barren.

The unfathomable wealth she squandered on bullshit throughout her mostly-anonymous lifetime of luxury... could have supported hundreds of other 20th century families. As specific example, she maintained a Santa Barbara mansion, for decades, without ever visiting the property.

That she was given it all from her father creating a superfund site... probably helps explain much of her reclusiveness [that and loss of sister at a young adult age].
