Development and Resources Corporation
The Development and Resources Corporation (D), founded and directed by David E. Lilienthal, operated from 1955 to 1979 and was based in New York City. D provided regional economic development services to governments throughout the world, often with a focus on the development of water resources and the construction of dams. Its main project was the development of the Khuzestan region of Iran. D's records document its development projects and business operations and include correspondence, contracts, data and maps, proposals and reports, and collected materials about each country.
