Frederick Kuh, 82, retired diplomatic and Washington correspondent for the Chicago Sun-Times, died Thursday in the Collingswood Nursing Center in Rockville.

He had been with the Sun-Times Washington bureau from 1951 until his retirement in 1964.

A noted international newsman, Mr. Kuh, had joined the staff of the Chicago Sun in London, in 1942, and remained the London correspondent after the merger of the Sun and the former Chicago Times. He continued in that capacity until coming to Washington.

He became known for such scoops as predicting Italy's surrender in World War II four days before it occurred; Bulgaria's peace terms 12 hours ahead of all opposition; the Soviet refusal to lift the Berlin blockade two days before the western governments announced it, and Allied conditions for peace in the Far East eight months before the Cairo Conference.

After coming here he covered the State Department and foreign embassies and also was sent abroad on major assignments.

Mr. Kuh had been honored by the Overseas Press Club, the Headliners Club, and Sigma Delta Chi, the professional journalists' society.

Born in Chicago, Mr. Kuh began as a reporter for the old Chicago Herald and the Chicago Evening Post. In 1919, he was hired by the London Daily Herald as its Balkan correspondent. Later he joined United Press and became its Moscow bureau chief.

He was transferred to Berlin but was forced out by Nai pressure in the 1930s and went to London.

He is survived by his wife, Renata, of the home in Rockville; two daughters, Renata Dorothy Kuh, of Washington, and Diane Josza, of Millburn, N. J., and two grandchildren.
