Eliot Coleman (born 1938) is an American farmer, author, agricultural researcher and educator, and proponent of organic farming. His 1989 book, The New Organic Grower, is important reading for organic farmers, especially market gardeners. He served for two years as Executive Director of the International Federation of Organic Agriculture Movements (IFOAM), and was an advisor to the U.S. Department of Agriculture during its 1979–80 study, Report and Recommendations on Organic Farming, a document that formed the basis for today's legislated National Organic Program (2002) in the U.S.
On his Four Season Farm in Harborside, Brooksville, Maine, he produces year-round vegetable crops, even under harsh winter conditions (for which he uses unheated and minimally heated greenhouses and polytunnels). He even manages to grow artichokes, claiming that "I grow them just to make the Californians nervous."
Coleman is currently married to gardening author Barbara Damrosch. For several years, from 1993, they co-hosted the TV series, Gardening Naturally, on The Learning Channel. Coleman and his wife continue to grow and locally market fresh produce.
In 1968, Coleman and his first wife, Sue Coleman, moved to a farm in Maine, situated on land purchased from Helen and Scott Nearing, as part of the back-to-the-land movement. Their first child, Melissa Coleman, was born there the next year. Coleman taught himself how to farm organically in the harsh Maine climate, and developed many of the cold-weather growing techniques for which he is known. As did the Nearings, the Colemans developed their farm into a learning center for people interested in natural and sustainable agricultural practices.
