Apple CEO Steve Jobs today 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."

It was just over a year ago that Jobs took his first medical leave of absence. At that time, Cook also filled in to run Apple's day to day operations.

Before joining Apple, Cook was vice president of Corporate Materials for Compaq and was responsible for procuring and managing all of Compaq’s product inventory. Previous to his work at Compaq, Cook was the chief operating officer of the Reseller Division at Intelligent Electronics.

Cook also spent 12 years with IBM, most recently as director of North American Fulfillment where he led manufacturing and distribution functions for IBM’s Personal Computer Company in North and Latin America.

Cook earned an M.B.A. from Duke University, where he was a Fuqua Scholar, and a Bachelor of Science degree in Industrial Engineering from Auburn University.
