A closer look
Lowenstein covers Buffett's 1960s American Express bet during the salad oil scandal, when he saw the brand would survive and bought heavily.
He shows how Buffett closed his partnerships in 1969 because he couldn't find good deals, a rare move for a manager.
The book also covers the Salomon Brothers scandal in 1991, when Buffett stepped in as interim chairman to save the firm's reputation.
Lowenstein spends time on the early partnership years, when Buffett wrote long letters to his partners explaining his thinking in plain words. Those letters set the tone for the later Berkshire reports. The book also shows his shift from buying cheap, weak companies toward paying fair prices for great ones, a change he credits largely to Charlie Munger.
