The New York Times – Janet Maslin: [Buffett's] opinions are so hotly sought that The Snowball, a biography with which he has enthusiastically cooperated, would be of interest even if it answered only softball questions. It approaches him seriously, covers vast terrain and tells a fascinating story. Mr. Buffett made a smart choice when he chose Alice Schroeder as his Boswell. Yes, he found an appreciative biographer with whom he seems to have a warm rapport. But he also found a writer able to keep pace with the wild swerves in the Buffett story and the intricacies of Mr. Buffett's Berkshire Hathaway business empire. Ms. Schroeder is as insightful about her subject's precise anticipation of current financial crises as she is about his quirky personal story. And she is a clear explicator of fiscal issues. This sprawling, colorful biography will mesmerize anyone interested in who Mr. Buffett is or how he got that way.
