Long [but good] Vanity Fair profile of Jamie Dimon, one of my favorite CEO’s and speakers:
Warren Buffett…, says that when Berkshire Hathaway bought the railroad Burlington Northern for $26 billion, in the fall of 2009, he called up Dimon on the Tuesday morning just prior to the public announcement of the deal and said, “Jamie, I need $8 billion!” “You got it,” Buffett says Dimon told him. “Even with some of the other big banks, that’s not something you could do on the phone,” Buffett adds.
… “Most corporate leaders hide and never say anything that they believe in,” says Warren Buffett. “…I think he knows as much about banking as anyone in the country, and he ought to talk about it. It would be a terrible thing for him not to voice his views.”
