Sylvia Mathews Burwell, currently president of global development at the Bill and Melinda Gates Foundation, will become president of the Walmart Foundation in 2012. She succeeds the retiring Margaret McKenna.

Among others, Burwell was a deputy chief of staff to President Bill Clinton.

The foundation is the charitable arm of the Walmart corporation, a separate entity from the Walmart Family Foundation, built by contributions from the Walton family, but it is part of the company’s pledge to spend $2 billion by 2015 on U.S. hunger.
