In the mid-1970s, an investor with tremendous business experience, Warren Buffett, became the business “coach” and confidant of the Washington Post‘s Katharine Graham. Graham became chairman and CEO of the newspaper company unexpectedly when her husband committed suicide. She leaned heavily on Buffett’s business judgment – especially when it came to the question of how to manage the business fund. Buffett addressed that critical question in a private letter to Graham.
