Top 10 most powerful couples in the world (With Pictures)

2. Melinda Gates and Bill Gates

With a net worth of $67 billion, Bill Gates is the United States’ richest man, and through the work of the foundation he founded and runs with wife Melinda, he’s also the world’s most generous. The couple’s Bill and Melinda Gates Foundation last year gave away $3.4 billion, and its primary goals this year have been to eradicate polio worldwide by 2018 and get modern contraceptives to another 120 million women by 2020; the Foundation has committed $140 million annually to this cause. Melinda, a Duke alum, delivered a commencement address at her alma mater this spring and encouraged the Class of 2013 to recognize “the boundless dignity of all people.”
