Dennis E. Puleston Ph.D (19 June 1940 – 29 June 1978) was an American archaeologist and ecologist. Puleston archaeology, biologyecology developed the ecological approach to the study of archaeology, looking at the manner in which humans adapt to their natural environment. His work involved pioneering interdisciplinarity methods which remain current to this day and led to a greater emphasis upon ecological and experimental archaeological research in the 80's and 90's. His work is still used to teach the importance of diversity in scientific interest, need for social relevance, and problem solving in archaeology classes due to the broadness of his approach. Puleston's work ranged from experiments in reconstruction and usefulness testing of chultuns or raised fields, building a traditional dugout canoe and using it to investigate otherwise unreachable areas, or challenging the belief that the Ancient Maya subsisted on a milpa agricultural complex – maize, beans, and squash. Life and career Puleston was born to Dennis and Elizabeth Rhode Puleston. He has one brother, Peter, and two sisters, Sally and Jennifer. His father was a noted ornithologist sailor, explorer, painter and environmentalist. It is from him that the younger Dennis learned a love of adventure, the outdoors, and science. According to puleston.org—a repository for a majority of Puleston's works and photographs from the field, Dennis “lived and worked in such places as the Canadian wilderness, the island of Moorea, Society Islands, and the tropical forests of Central America which he came to love deeply.” Dennis attended high school at Bellport High School, in Brookhaven, New York, and upon graduating embarked on his own adventures. A great illustration of his adventures and eventual decision to become an archaeologist is found in the following excerpt from Harrison and Messenger's obituary: Before beginning formal study of biology at Antioch College, he [Dennis] spent a season working with the National Film Board of Canada as assistant in the production of a cinematic study of tundra ecology. During the years of study at Antioch, Denny’s interest in archaeology developed through a series of contacts and field experiences. In 1960 he worked as a student assistant under Roland Force and Paul S. Martin in the Chicago Natural History Museum. It was Paul Martin who arranged a visit for Denny and a classmate to Tikal in Guatemala via a letter of introduction to Edwin S. Shook, then director of the project. When they arrived in Guatemala the
