The Peru Project was a foreign assistance program in the South American country of Peru. It was North Carolina State College’s first major international activity. In 1953, the U.S. State Department invited the college’s School of Agriculture to explore the development of a program to provide technical assistance to the Peruvian Ministry of Agriculture and one of the Peruvian colleges. The program officially began in January 1955, when R. W. Cummings headed a six-member team to the country. Cummings was succeeded by Jack Rigney. The project was renewed after the initial three-year period, and it was greatly expanded during the 1960s. By the time the project’s mission ended in 1973, 81 faculty members had worked in the country and 200 Peruvians had been trained in the United States. In 1982, the School (College) of Agriculture and Life Sciences was invited back to Peru to assist with agricultural research and extension.
The North Carolina State Univeristy Peru Project records are comprised of correspondence, reports, manuals, newspaper clippings, photographs, newsletters, and other documents created and collected during the course of the project. Materials range in date from 1953 to 1995.

Historical Note
The Peru Project was a foreign assistance program in the South American country of Peru. It was North Carolina State College’s first major international activity. In 1953, the U.S. State Department invited the college’s School of Agriculture to explore the development of a program to provide technical assistance to the Peruvian Ministry of Agriculture and Universidad Agraria. The program officially began in January 1955, when R. W. Cummings headed a six-member team to the country. Cummings was succeeded by Jack Rigney. The project was renewed after the initial three-year period, and it was greatly expanded during the 1960s. It was partially funded by the Rockefeller Foundation and the Ford Foundation. By the time the project’s mission ended in 1973, 81 faculty members had worked in the country and 200 Peruvians had been trained in the United States. In 1982, the School (College) of Agriculture and Life Sciences was invited back to Peru to assist with agricultural research and extension.
Scope and Content Note
The North Carolina State Univeristy Peru Project records are comprised of correspondence, reports, manuals, newspaper clippings, photographs, newsletters, and other documents created and collected during the course of the project. Materials range in date from 1953 to 1995.
Organization of the Collection
The records of the North Carolina State University Peru Project are arranged in three series: Program Records, Reports and Office Records. The Program Records series begin alphabetically with bound files but finish in the original order. The Reports and Office Records were processed according to original order as most of it came in labeled folders.
