Joseph S. Evans Jr., 69, a former foreign correspondent and retired Foreign Service officer, died of a liver ailment Sept. 12 at Sibley Memorial Hospital.

He began his government career with the U.S. Embassy in London where he directed its information and cultural affairs activities. He later worked for the old U.S. Information Agency (USIA) in Tokyo and Buenos Aires.

From 1958 to 1962, Mr. Evans served as inspector general of USIA, and later worked as public affairs director for the U.S. civil administration of the Ryukyu Islands, before retiring in 1971.

He had worked as a reporter and editor for the old New York Herald Tribune during the 1930s, and later helped cover the Battle of Britain for that paper.

He joined Newsweek magazine's European staff in 1943, was a CBS correspondent in Washington in 1947, and Marshall Plan spokesman in London in the late 1940s and early 1950s.

Mr. Evans had been president of the Allied War Correspondents in Paris in 1947, and president of the Association of American Correspondents in London in 1946.

He had been awarded the Medal of Freedom in 1945 and the Army's Outstanding Civilian Service Medal after retiring from the USIA.

He was a native of Quincy, Mass., and a 1931 graduate of Yale University.

Survivors include a sister, Ruth Ann Evans, of Schenectady, N.Y.

The family suggests that expressions of sympathy be in the form of contributions to the scholarship fund, the National Press Club Foundation.
