Born and raised in Brooklyn, New York, Samuel Kaymen -- the "NOFA prophet" -- was privy to all the movements and motivations of the 1960s. Like many others in his time, Kaymen felt that his life was spiritually undernourished, and in 1969, he moved from the city to rural Unity, New Hampshire, to start a self-sufficient garden with his wife, Louise.

With no previous experience in agriculture, Kaymen learned all he could from outdated library books, eventually stumbling across Edward Hyams' . Hyams argued that "the first thing a civilization loses is its topsoil," and that the fall of all the great civilizations of the past could be linked to agricultural collapse. Kaymen was shocked. "I didn't know that agriculture was important," he wrote, "I thought that food was assembled in the backs of grocery stores!" But with his surprise came inspiration. Kaymen would start an organization of like-minded growers who would farm in an organic, natural, and sustainable way. In 1971, now living in Westminster, New Hampshire, Kaymen founded the Natural Organic Farming Association.

The first meeting of NOFA (which would change the first part of its name to "Northeast" in 1993) took place on June 7, 1971. Kaymen had posted fliers and sent out mailers announcing that NOFA would teach and promote nine principles, including proper composting, seeding, weeding, and other skills necessary for farm production. Conspicuously missing from the list was marketing. "This shows how naive I really was," Kaymen said in 1998. Starting with a budget of $35, Kaymen and the farmers, gardeners, and hippies who attended that first meeting decided that NOFA would sponsor seminars, seed-exchanges, bulk shopping, and apprenticeships. They would also publish a quarterly newsletter named after what Kaymen hoped to be, .

Eventually, Kaymen "hooked up with people in New York City who were running daycare centers" and at least once a week, NOFA farmers would load up an old truck in the middle of the night and drive six hours to Manhattan and Harlem to deliver fresh produce to daycare centers and to people on street corners who "hadn't seen fresh collards since they were in the South."

In 1973, Kaymen was given a farm in Cornish, New Hampshire, by a group of people who thought he "was a good organizer... a good speaker and [who] wanted [him] to be a New Hampshire person." Robert Houriet, a farmer and writer living in Hardwick, Vermont, offered to take over , and according to Kaymen, "it immediately became a thousand percent better." With Kaymen in New Hampshire and reaching more people than it ever had before, NOFA became truly a multi-state organization.

The first NOFA conference, cosponsored by the Biodynamic Farming Association, was held in Wilton, New Hampshire, in 1975. Wendell Berry was the keynote speaker and around 350 people attended, which Kaymen thought was "quite a lot." Win Way, a member of the University of Vermont faculty ("the establishment" as Kaymen called it), brought air of the academy to the 1976 conference which helped transform NOFA from a group of former New York City hippies into an influential organization with scientific backing. The 1978 conference saw the "old timers... come out of the closet" to support NOFA.

Kaymen stepped down from NOFA's presidency in 1981. Since that time, NOFA has grown, now claiming "nearly 4,000 farmers, gardeners and consumers [from] ... chapters in Connecticut, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island and Vermont." NOFA started as a co-operative promoting and facilitating information sharing and other ways to help growers farm in a natural, organic, and sustainable way. While NOFA still promotes the nine principles Kaymen originally founded it to promote, that tenth item, marketing, now plays a larger role than ever before.
