The Bill & Melinda Gates Foundation builds on and consolidates previous family and corporate philanthropic efforts established to promote public health and disease control in the Third World, expand library access to new information technology, and enhance public education. The Foundation is technically a philanthropic trust guided by Microsoft co-founder William H. "Bill" Gates III (b. 1955) and his wife Melinda (French) Gates (b. 1965), and directed by his father, William H. Gates II (b. 1927) and former Microsoft executive Patty Stonesifer (b. 1957).
