Innovation Period
1970 - 1999

Expanding Investments, Improving Sustainability
North Carolina courts grant Endowment Trustees relief from provisions in the Indenture of Trust that strictly limit the Endowment’s investments beyond Duke Power stock to certain types of government bonds. Throughout the 1970s, Trustees work to amend these investment provisions to ensure the Endowment’s long-term sustainability.

Mary Duke Biddle Trent Semans Chair of the Board of Trustees
Granddaughter of Ben Duke, Mary D.B.T. Semans continued the family’s charitable legacy by serving as an Endowment Trustee for 55 years and the first female Chair. She served as a Trustee for numerous institutions, including Duke University and the Mary Duke Biddle Foundation. Mrs. Semans received the Duke University Medal for Distinguished Meritorious Service; the National Brotherhood Award from the National Conference of Christians and Jews; and the John Tyler Caldwell Award for the Humanities. She was a 2009 inductee in the North Carolina Women’s Hall of Fame. Mrs. Semans was Chair of The Duke Endowment’s Board from 1982 to 2001 and Chair Emerita 2002 until her death in 2012.

Exceeding $1 Billion in Grants Distributed
In 1992, the Endowment surpasses $1 billion in grants distributed since its inception.

Promoting Family-Centered Solutions
The Duke Endowment invests in pioneering work to enhance family-centered practices in children’s homes. It awards the first grants for child welfare and early intervention for children at risk of losing their families.

Selling Duke Power Stock
A year after Doris Duke (Mr. Duke's only child) passes away, Trustees sell roughly 60 percent of the Endowment’s investment in Duke Power – a move Doris Duke had opposed but other Trustees felt necessary to reduce the Endowment’s financial dependence on the electric utility.

Shifting Our Focus for Greater Effectiveness
The Endowment shifts its grantmaking focus toward cross-program grants and special programs; only 12 percent of grants fund brick-and-mortar projects.

Serving “Vulnerable Children”
The Endowment updates its definition of “orphan” to reflect support for more inclusive programs serving vulnerable children.
