1. Oprah Winfrey
No doubt Winfrey is one of the most recognizable names on the planet, but when shes not promoting books or self-improvement, the talk-show-host-turned-philanthropist is using her star power to lift up women and girls.
The Oprah Winfrey Foundation has awarded hundreds of grants, and millions of dollars, to organizations that educate and empower women and families nationally and globally. One of her most well-known initiatives was the $40 million school for girls she built in South Africa, which opened in January 2007 and now serves grades 7 through 12. She also created The Oprah Winfrey Scholars Program, which gives scholarships to students nationally and abroad. Although her talk show will wind down in September, Winfreys mission to work for a better world for women and girls will continue.
