Donald Louis Ranard, 73, a retired Foreign Service officer and former director of the Center for International Policy, a nonprofit Washington research group, died of leukemia July 28 at Georgetown University Hospital.

Mr. Ranard was a former chief of Korean affairs at the State Department. His testimony before a House subcommittee on international organizations after his 1974 retirement provided one of the early leads in the unraveling of the "Koreagate" scandals of the late 1970s.

Mr. Ranard, who lived in Centreville and Romney, W.Va., was a native of Taunton, Mass. He graduated from Brown University.

He came to Washington during World War II, when he joined the War Department. He later transferred to the U.S. Information Agency. After the war, he had overseas assignments in Tokyo.

He joined the Foreign Service in 1956. He was consul in Seoul from 1959 to 1962, and deputy chief of mission in Rangoon, Burma, from 1965 to 1970.

He then served briefly in Australia before becoming chief of Korean affairs at the State Department.

It was while he was in this post, according to news accounts, that Mr. Ranard became aware of intelligence reports that led him to believe that people in the South Korean government were involved in influence-peddling schemes involving members of the United States Congress. He testified about this before the House subcommittee on international orgainzations after retiring.

A staff member on the subcommittee said of Mr. Ranard's information, "He gave us a starting point . . . . Without him, we wouldn't have had an investigation."

Mr. Ranard became director of the Center for International Studies in 1976. He retired in 1986.

In 1985, the North American Coalition for Human Rights awarded him its Human Rights Award.

Survivors include his wife, Virginia Adams Ranard of Centreville, and five children, Patricia Louise Ranard of New York City, Donald Adams Ranard of Arlington, Andrew Benson Ranard of Tokyo, John Kent Ranard of New York City and Amy Skinner Ranard of Fairfax.
