Nature Museum to Honor “First Family for Environment”

Sidamon-Eristoffs have long history of green activism

The Hudson Highlands Nature Museum will honor the Sidamon-Eristoff family at its annual champagne brunch at noon on Sunday, Nov. 8 at the Powelton Club in Newburgh. This museum has named the Sidamon-Eristoff family as a “first family for the environment.”

The late Constantine Sidamon-Eristoff served as Region II Director of the Environmental Protection Agency; as founding chairman of Audubon New York, as director of National Audubon, the New York League of Conservation Voters, Orange County Citizens Foundation and the Orange County Planning Board as well as a member of the Advisory Board of Constitution Marsh Audubon Center and Sanctuary. His sister Anne is also a longtime supporter and advocate for the Hudson Highlands Land Trust and environmental causes in the Valley.

Anne P. Sidamon-Eristoff is chairman emerita of the American Museum of Natural History and a longtime trustee of the Hudson River Foundation, the World Wildlife Foundation, Storm King Art Center, New York Community Trust and the Black Rock Forest Consortium. She also served as a trustee of Scenic Hudson and the Hudson Highlands Nature Museum.

The couple’s children, Simon, Elizabeth and Andrew, and their spouses have continued the legacy with support for land conservation, historical preservation and countless environmental causes, both in the Hudson Valley and across the country.

The museum will host a silent auction during the brunch to support its environmental education programs. Tickets, which start at $125 per person, are available at or by calling 845-534-5506 ext. 204. The Powelton Club is located at 29 Old Balmville Road.
