Warren Buffet's father Howard was a great member of the Old Right. From the Rothbard archives, here at LvMI, here is a letter from Howard to Rothbard. Robert Wenzel has a great analysis of this:
Warren Buffett's Father Tried to Teach Warren About Austrian Business Cycle Theory: I wonder what went wrong... Note the second to last paragraph where Howard Buffet writes: 'Somewhere I had read that you wrote a book on the "Panic of 1819". If this is correct, I would like to know where I can buy a copy of it. I have a son who is a particularly avid reader of books about panics and similar phenomenon. I would like to present him with the book referred to.'
