Tibor Bartok, 80, for 25 years a producer of overseas programs for the Voice of America before his retirement several years ago, died Feb. 18 at the Washington Hospital Center after a heart attack.

In his long association with VOA, Mr. Bartok, who lived in Washington, worked for various foreign language divisions of the agency, the last being the Latin American service.

Mr. Bartok was born and raised in Budapest, Hungary. While a student in Berlin, he became a correspondent for a number of Hungarian newspapers. When he settled in the United States in the early 1930s, he wrote for and edited various Hungarian-language publications in this country.

He volunteered for service for two years with the Army during World War II. During his tour of duty, he edited a regimental newspaper called The Target.

Mr. Bartok cultivated a lifelong interest in classical music, particularly chamber music, and was personally close to the players of the Budapest Quartet for many years. He helped arrange an exhibit honoring the ensemble at the Library of Congress, and in 1968 collaborated with critic Alan M. Kriegsman of The Washington Post on an article, "Farewell to the Budapest Quaartet," for The Saturday Review.

He is survived by his wife, Sidonie S. Bartok of Washington.
