Jamie Dimon, JPMorgan Chase's chairman and CEO, underwent emergency heart surgery Thursday, the bank said in a memo to employees, clients, and shareholders. He is in recovery.

"We want to let you know that Jamie experienced an acute aortic dissection this morning," the memo said. "He underwent successful emergency heart surgery to repair the dissection."

Dimon, 63, is "awake, alert, and recovering well," the memo said.

Daniel Pinto and Gordon Smith, two senior executives with JPMorgan, will lead the bank while Dimon recovers, the memo said.

Dimon has been CEO of chairman of JPMorgan since January 2006, and as Business Insider's Dakin Campbell has reported, enjoys a reputation as the best banker, or among the best bankers, of his generation. He's also taken a lead as the chairman of the Business Roundtable in advocating a more community-minded form of capitalism.
