Atkinson Center for a Sustainable Future, a research center focused on the challenges facing energy, the environment, and economic development around the world. Mr. Atkinson earned a bachelor’s degree in 1960 from Cornell’s College of Agriculture and Life Sciences. Mr. Atkinson grew up near New Egypt, N.J., on a poultry farm that his father, who had only a ninth-grade education, ran successfully.
