Development and Resources Corporation
The Development and Resources Corporation (D&R), founded and directed by David E. Lilienthal, operated from 1955 to 1979 and was based in New York City. D&R 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&R'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.
