Roger Lowenstein begins his new biography of Warren Buffett with a disclaimer. He reveals that he is a longtime investor in Berkshire Hathaway, the company that under Buffett’s guidance has seen its share price rise in 33 years from $7.60 to approximately $30,000.

In reviewing Lowenstein’s book, I must begin with a disclaimer, too. I can’t be neutral or dispassionate about Warren Buffett, because we’re close friends. We recently vacationed together in China with our wives. I think his jokes are all funny. I think his dietary practices—lots of burgers and Cokes—are excellent. In short, I’m a fan.

It’s easy to be a fan of Warren’s, and doubtless many readers of Buffett: The Making of an American Capitalist will join the growing ranks. Lowenstein’s book is a straightforward account of Buffett’s remarkable life. It doesn’t fully convey what a fun, humble, charming guy Warren is, but his uniqueness comes across. No one is likely to come away from it saying, “Oh, I’m like that guy.”
