Doris Duke Foundation
The Doris Duke Foundation (DDF) is a charitable foundation based in the United States. It was established in 1996, following the 1993 death of billionaire heiress Doris Duke, who bequeathed the bulk of her $1.2 billion fortune to the Foundation, with the mission of providing grants for performing arts, the environment, education, child welfare, medical research, and fostering goodwill and inclusion with the Muslim community of the United States.
