Bill Clinton

Founder and Board Chair, Clinton Foundation and 42nd President of the United States

William Jefferson Clinton, the first Democratic president in six decades to be elected twice, led the U.S. to the longest economic expansion in American history, including the creation of more than 22 million jobs.

Within these three programmatic areas, the Foundation’s work ranges from helping farmers in Africa increase their yields and incomes to mobilizing relief efforts in the wake of natural and man-made disasters; from confronting public health crises such as the opioid epidemic, heart disease, diabetes, and childhood obesity to combating the effects of climate change in the Caribbean through clean and renewable energy efforts. In addition, the Foundation is committed to cultivating a diverse, new generation of leaders. This includes programs that help students create change on their college campuses; support networks that foster women’s leadership in the renewable energy and artisan sectors; and a historic partnership among the presidential centers of Presidents Clinton, George W. Bush, George H.W. Bush, and Lyndon B. Johnson.
