Eugene Rosenfeld, 84, who retired from the U.S. Information Agency in 1975 after serving as press attache at the embassy in London, died of pneumonia and kidney failure Nov. 1 at his home in Washington.

Mr. Rosenfeld, who acted as spokesman in London for Ambassadors Walter Annenberg and Elliot Richardson, was a former assistant director for public information at USIA.

He served as an information officer in India, where he worked under ambassadors who included John Kenneth Galbraith, and as U.S. information director in Tanzania and Ethiopia. In the late 1960s, he was chief U.S. spokesman in Saigon during the Tet offensive.

Mr. Rosenfeld was born in New York and raised in Lynbrook, N.Y.

He attended New York University and worked as a reporter for newspapers that included the Long Island Daily News and the Brooklyn Eagle.

He began his Washington career in the early 1940s with the Census Bureau and then transferred to the Office of War Information.

He was posted to London during World War II, where he was a writer-editor with the Supreme Headquarters Allied Expeditionary Force. After the war, he helped set up the reports section of the U.S. delegation to the United Nations.

Mr. Rosenfeld was also a jazz pianist who had played with orchestras at the Willard Hotel and elsewhere.

He was an organizer in the early 1940s of the Washington Workshop, a group that sponsored concerts before racially integrated audiences in then-segregated Washington.

Mr. Rosenfeld was founding president of the USIA Alumni Association.

He was co-author, with his wife, Chris Prouty Rosenfeld, of "The Historical Dictionary of Ethiopia" and "The Historical Dictionary of Ethiopia and Eritrea."

He served two terms with the Board of Professional Responsibility of the D.C. Court of Appeals and was a volunteer with the National Archives.

He is survived by his wife of 55 years, of Washington; four children, Megan Rosenfeld of Washington, Eric Rosenfeld of Rockville, Steven Rosenfeld of Florence and Peter Rosenfeld of Albany, Calif.; and five grandchildren.
