Mark Zuckerberg and his wife welcome baby girl into a flawed world

Mark Zuckerberg and his wife Priscilla have welcomed Max, their baby girl, into the world.

Zuckerberg announced the birth in a Facebook note on Tuesday.

"Your mother and I don't yet have the words to describe the hope you give us for the future. Your new life is full of promise, and we hope you will be happy and healthy so you can explore it fully. You've already given us a reason to reflect on the world we hope you live in," he wrote.

Zuckerberg also took the opportunity to announce the Chan Zuckerberg Initiative, a nonprofit that will look "to join people across the world to advance human potential and promote equality for all children in the next generation. Our initial areas of focus will be personalized learning, curing disease, connecting people and building strong communities."

Zuckerberg had already signed a pledge to The Giving Pledge, a promise signed by wealthy individuals to donate most of their fortune. He said that the couple would be donating 99% of their Facebook shares to the cause, currently worth around $45 billion.

The happy couple also released a video about the excitement for the baby and why they started the Chan Zuckerberg Initiative.

Chan and Zuckerberg announced her pregnancy in late July. The couple have been married since 2012.

The new initiative follows on other major philanthropic efforts by Zuckerberg including a $20 million donation to provide public high schools with high speed Internet, a $75 million donation to a San Francisco hospital and $100 million to the Newark school system.
