NH founder of a yogurt empire

Samuel Kaymen founded Stonyfield Yogurt in 1983. The company is now run by Gary Hirshberg, but Kaymen has stayed involved as a board member. He started out as an engineer in the aerospace industry. But sometime around 1963, he began to feel something was missing from his life; with a young family, he became interested in organic farming and the environment. He and his wife found a house and farm in New Hampshire, and Stonyfield Yogurt was borne out of an attempt to teach others about organic farming. He talks about the difficulties he and his company faced in the early days, and compares the history of his company to that of Ben and Jerry?s ice cream.
