Alida Rockefeller Messinger

Alida Ferry Rockefeller Messinger (born 1948) is an American philanthropist and the youngest daughter of John Davison Rockefeller III.
Early life and family.
Messinger was born in 1948. She is the youngest daughter of John Davison Rockefeller III (1906–78) and Blanchette Ferry Hooker (1909–92), and a fourth-generation member of the Rockefeller family. Her brother is former Senator John Davison "Jay" Rockefeller IV (born 1937).
Messinger's father began to teach her about philanthropy when she was five years old. She has said, "My father and mother's greatest fear was that their four children might take their wealth for granted and grow up spoiled and arrogant ... They wanted us to learn early that with wealth comes responsibility."

Messinger is a major donor to conservation and environmental organizations. Her Alida R. Messinger Charitable Trust also funds conservation and environmental groups, as does the Rockefeller Family Fund, founded in 1967, of which she is a trustee.
