David E. Lilienthal, 56, longtime head of TVA and first chairman of the Atomic Energy Commission, became chairman and chief executive officer of newly organized Development & Resources Corp. President of the company, backed by the Manhattan investment banking firm of Lazard Freres & Co., is Gordon R. Clapp, 49, who succeeded Lilienthal as TVA chairman and resigned recently as deputy city administrator of New York City. Development & Resources Corp. will act as a consultant to foreign governments in TVA-type river and land development programs, coordinate other private or public projects such as atomic-energy production in power-short countries.
