Bill Gates in 1994 sold some of his Microsoft stock to create the “William H. Gates Foundation.” In 2000, Gates and his wife combined three family foundations to create the charitable “Bill & Melinda Gates Foundation,” which was identified by the Funds for NGOs company in 2013 as the world’s wealthiest charitable foundation, with assets reportedly valued at more than US$34.6 billion. The Foundation allows benefactors to access information that shows how its money is being spent, unlike other major charitable organizations such as the Wellcome Trust.
Gates has credited the generosity and extensive philanthropy of David Rockefeller as a major influence. Gates and his father met with Rockefeller several times, and their charity work is partly modeled on the Rockefeller family’s philanthropic focus, whereby they are interested in tackling the global problems that are ignored by governments and other organizations. As of 2007, Bill and Melinda Gates were the second-most generous philanthropists in America, having given over US$28 billion to charity; the couple plan to eventually donate 95 percent of their wealth to charity.
