On December 1, Mark Zuckerberg wrote a letter to his newborn daughter, Max, and shared it with the world (on Facebook, of course). The letter announced the commitment of Zuckerberg and his wife, Priscilla Chan, to improve the world in which their daughter will grow up, which included the creation of the Chan Zuckerberg Initiative, a limited liability company whose mission is to “advance human potential and promote equality in areas such as health, education, scientific research, and energy.” Mr. Zuckerberg further stated in the letter his intent to give away for such purposes during his lifetime 99 percent of his shares in Facebook, currently valued at $45 billion.
