Mark Zuckerberg Priscilla Chan daughter Mark Zuckerberg is officially a dad. He announced the birth of his daughter, Maxima, today in a note on Facebook, and also announced that he and his wife Priscilla Chan will give away 99 percent of their Facebook shares over their lifetime to provide “a world better than ours today.”

The shares, which are currently worth about $45 billion, will be used to build up the recently launched Chan Zuckerberg Initiative. Zuckerberg and Chan said in the note, addressed to their daughter, that they hope her generation focuses on advancing human potential and promoting equality.

A few weeks before Max’s birth, Priscilla and Mark took a morning to reflect and record their hopes for their daughter and all children of her generation.

In the letter, Zuckerberg and Chan tout personalized education, access to the internet and better healthcare as steps toward a better world for their daughter.

Zuckerberg’s past philanthropic efforts haven’t been universally praised. Facebook’s Internet.org has been blasted for providing a tightly controlled internet experience for developing nations. His $100 million donation to Newark schools was poorly used and resulted in little change.

The letter is already drawing ire on Twitter, where some are questioning the Chan Zuckerberg Initiative’s causes.

However, Zuckerberg recently teamed up with Bill Gates and other tech giants to invest in zero-carbon energy tech, a move that has so-far received high praise.

Besides the photo shared in the note, Zuckerberg has yet to post any photos of baby Max to his public page. Maybe someone needs to teach him how parents use Facebook …
