When Carol Loomis first mentioned a little-known Omaha hedge fund manager in a 1966 Fortune article, she didn’t dream that Warren Buffett would one day be considered the world’s greatest investor—nor that she and Buffett would quickly become close personal friends. As Buf­fett’s fortune and reputation grew over time, Loomis used her unique insight into Buffett’s thinking to chronicle his work for Fortune, writ­ing and proposing scores of stories that tracked his many accomplishments—and also his occa­sional mistakes.

Now Loomis has collected and updated the best Buffett articles Fortune published between 1966 and 2012, including thirteen cover stories and a dozen pieces authored by Buffett himself. Loomis has provided commentary about each major arti­cle that supplies context and her own informed point of view. Readers will gain fresh insights into Buffett’s investment strategies and his thinking on management, philanthropy, public policy, and even parenting.
