About Us

photo of Maurice Wertheim


Maurice Wertheim (1886–1950) was a New York investment banker, philanthropist, and environmentalist who owned 1800 acres of land along the Carmans River, which he used for conserving wildfowl and hunting. In 1947, he and his wife Cecile donated all of this property to the U.S. government as a gift for the American people.

Dennis Puleston (1905-2001) was a British-born American envirnmentalist, adventurer and wildlife artist.  His life-long interest in birds led him to work to prevent the continued use of DDT, which had caused Long Island’s osprey population to decline.   After securing a ban, Puleston and his colleagues founded the Environmental Defense Fund.  A senior naturalist, he also painted and wrote extensively about Long Island wildlife.

Claire Goad’s fifty years of love and dedication to the Refuge System and FoW has left a valuable legacy to continue.  Her tireless advocacy with federal officials was instrumental in getting the Visitors Center built (she is pictured speaking at the opening ceremony).

The Refuge gives children an opportunity to discover nature and to return to it over and over–with wonder and appreciation. They will be the next stewards of our Refuge and the environment.
