Bill Gates credits the philanthropic work of David Rockefeller as a major inspiration for him, and his charity work is in part modelled after the Rockefeller family’s focus on tackling global problems that aren’t given sufficient attention by governments and other organizations.

The Bill and Melinda Gates Foundation

Bill Gates created the William H. Gates Foundation in 1994. In 2000, Bill and his wife Melinda combined three family foundations to create the Bill & Melinda Gates Foundation, and Gates donated stock valued at $5 billion to it. By 2013, it was the world’s wealthiest charitable foundation, with assets valued at more than $34 billion.

The foundation is organized into four main areas:

  • Global Development
  • Global Health
  • United States
  • Global Policy & Advocacy

Unlike many other foundations, the Bill & Melinda Gates Foundation makes it easy for benefactors to access information about how the fund’s money is being spent.

The Giving Pledge

As a co-founder of The Giving Pledge, Gates was one of the first people to sing it. He signed it on 9 December, 2010, the same day as Warren Buffett and Mark Zuckerberg.
