She was also notoriously abusive towards staff and her family. That was the reason why her family forced her to retire initially (iirc, and I may be misremembering this, she only has one biological son...the other two married her daughters and they were, perhaps understandably, not keen to carry on after the sale because of the abuse).

Do you have a source for her abuse? A quick search didn’t turn up anything—your comment is the top google result :)

Here's something from http://www.quoteswise.com/rose-blumkin-quotes.html :

>[To Warren Buffett when she had lined up a group of her grandsons and sons-in-law and nephews against a wall and was lecturing them.] See all these guys next to me? If I sell it to you, you can fire them. These people are a bunch of bums, and they are all related to me and I can’t fire them. But you can fire them. They’re bums, bums, bums. [‘She went on like this for an hour, literally. The word ‘bums’ recurred many, many times. Then she dismissed me. I had served my purpose.’ – ###Warren Buffett

The other quotes are quite an interesting read also.

Seriously, the ranking of HN comments in organic Google results is a little bit off-putting in some cases.

Someone dialed up the weights on HN comments way past where IMO a potentially throwaway remark should be scored.

And I say this as someone who tries to make substantive and significant HN posts on the regular.

As I said somewhere else, you should check out Alice Schroder's chapter on NFM in her Buffett bio for a source.
