Steve Jobs, perhaps the most valued CEO in America, will temporarily leave Apple for health reasons, the company announced today. A short media advisory did not disclose any specifics about Jobs' condition. Two years ago, the Apple chief took another leave of absence during which he had a liver transplant as part of his treatment for pancreatic cancer. We wish Jobs well.

The public disclosure followed Jobs' internal announcement. He sent the following email to all Apple employees:


At my request, the board of directors has granted me a medical leave of absence so I can focus on my health. I will continue as CEO and be involved in major strategic decisions for the company.

I have asked Tim Cook to be responsible for all of Apple's day to day operations. I have great confidence that Tim and the rest of the executive management team will do a terrific job executing the exciting plans we have in place for 2011.

I love Apple so much and hope to be back as soon as I can. In the meantime, my family and I would deeply appreciate respect for our privacy.

Chief Operating Officer Tim Cook will lead the company while Jobs is out.
