Joseph, who will speak at 7 p.m. Jan. 17 in Pruis Hall, is professor of the practice of public policy studies and executive director of the United States-Southern Africa Center for Leadership and Public Values at Duke.

Nominated by President Bill Clinton and confirmed by the U.S. Senate in 1995, Joseph was the first and only American ambassador to present his credentials to President Nelson Mandela. In 1999, President Thabo Mbeki awarded him the Order of Good Hope, the highest honor the Republic of South Africa bestows on a citizen of another country.
