John Todd (biologist)

This article refers to the biologist John Todd. For the US evangelist, see John Todd (evangelist).

Dr. John Todd (1939- ) is an important biologist working in the field of ecological design. His ideas often involve applications that make use of alternative technologies. His principle interests include solving the problems of food production and waste-water processing. As an author, he has presented the outcome of the work that he and colleagues have undertaken in a series of books, as well as in the requisite scientific papers.

Todd was born in Hamilton, Ontario, Canada in 1939. He earned his B.Sc. (1961) in agriculture and his M.Sc. (1963) in parasitology and tropical medicine at McGill University in Montreal, Quebec, after which he did doctoral work in fisheries and oceanography at the University of Michigan. His early professional interest, involving the behavioral ecology of fish, was the basis of his work as an assistant professor of ethology at San Diego State University (1968-1970), after which he joined the Woods Hole Oceanographic Institution in Woods Hole, Massachusetts, as an assistant scientist.

John Todd's wife, Nancy Jack Todd, trained as a dancer and is a skilled writer and editor. She has edited and added introductions to many of John Todd's books, and co-written the most recent. Back in the Woods Hole days, John had begun to develop his ideas about how complicated biological food chains worked, and in their conversations Nancy wondered if ecological concepts could serve people's needs. She suggested science needed "a human face."

In 1969 John and Nancy Todd co-founded the New Alchemy Institute to do both fundamental research into aspects of biology and deciplines as well as to apply biological science to technology. Todd and colleagues have designed miniature ecosystems, largely self-perpetuating, which bring ecological principles into service of human requirements. Besides designing and prototyping food-producing systems and approaches for communities of people, this work has resulted in innovative new approaches to processing sewage and industrial waste water. Todd's approach has involved applications of micro-organisms, fish, and plants (phytoremediation).

Todd and colleagues have developed what they call "Living Machines." In principle, a Living Machine is an ecologically engineered technology developed to restore, conserve, or remediate sewage or other polluted water, by replicating and accelerating the natural purification processes of streams, ponds and marshes. In practical application, a Living Machine is a self-contained treatment system designed to treat a specific waste stream using the principles of ecological engineering. It does this by using diverse communities of bacteria and other microorganisms, algae, plants, trees, snails, fish and other living creatures.

Todd served as NAI's President until 1981. In 1980, he co-founded Ocean Arks International. He also co-founded Living Technologies Inc., an ecological design, engineering, and construction firm in Burlington, Vermont. From 1999 he has been Research Professor & Distinguished Lecturer in the University of Vermont.

While John Todd has pursued much of his work with the developing world in mind, applications for the benefit of industrialized and affluent societies have been part and parcel.

Among the awards Dr. Todd has received have been, in 1994, the Daimler/Chrysler Award for Innovation in Design, in 1996, the Environmental Merit Award (from the US Environmental Protection Agency), in 1998, the Bioneers Lifetime Achievement Award; also in 1998, he and Nancy Jack Todd together received the Lindbergh Award in recognition of their work in technology and the environment. John Todd was profiled in Inventing Modern America, published by the Lemelson-MIT Program for Invention and Innovation, in which story of the development of his innovative ecological waste treatment systems is highlighted.
