The Dennis Puleston Environmental Fund is named in memory of Brookhaven resident, naturalist Dennis Puleston.

Dennis Puleston (30 December 1905 – 8 June 2001) was a British-born American environmentalist, adventurer and designer. He is perhaps best known for playing a key part in securing a nationwide ban in the United States on the use of the pesticide DDT, a decision regarded as the first important success of the emerging environmental movement. As a result of this ban, he helped save his favorite bird, the osprey, from extinction in North America. He was co-founder and the first chairman of the Environmental Defense Fund. Puleston also co-designed the DUKW, an amphibious vehicle used in World War II. Dennis Puleston called Brookhaven Hamlet his home.
