Mr. Byington, a resident of Soto Grande, Spain, was born in Naples, where his father was the U.S. vice consul. He grew up in Europe and the United States. He entered the Foreign Service after his graduation from Yale University in 1930.

During World War II, Mr. Byington was a State Department press officer in Washington and was part of the U.S. delegation to the San Francisco Conference that established the United Nations.

In the immediate postwar years he was deputy political adviser at Allied headquarters in the Mediterranean theater, and for this work he received the Medal of Freedom.

In 1957, Mr. Byington was appointed ambassador to Malaya. He remained there for four years.

Much of his career was spent in Italy. In the 1930s he had been a consular officer in Naples and after his assignment in Malaya he returned there as consul general. He stayed in that post until 1973, when he retired to Soto Grande.

Mr. Byington was a member of the Metropolitan and Chevy Chase clubs in Washington.

GERTRUDE MANHAL,

86, a World War II concentration camp prisoner and former Czech diplomat who became an accountant in Washington, died of cardiac arrest Oct. 25 at her home in Washington.

Miss Manhal moved to the Washington area in 1949 when she went to work for the old Council for a Free Czechoslovakia. She earned an accounting degree at Benjamin Franklin University and in 1954 she joined H. Zinder & Associates, a Washington accounting concern. She retired there in 1981.

Miss Manhal was born to Czech parents in Munich. In 1920, she entered the foreign service of the newly independent nation of Czechoslovakia and spent the next seven years at its consulate in Munich.

She served next with the Czech legation in Sofia, Bulgaria, and held posts with Czech diplomatic missions in the Middle East. In 1937, she joined the Foreign Ministry staff in Prague.

In the late 1930s, Germany annexed parts of Czechoslovakia and occupied most of the rest of the country. In 1944, while assisting the Czech underground, Miss Manhal was arrested in Prague by German occupation authorities. In 1945, she was liberated from Ravensbruck concentration camp by Allied forces.

After nearly a year in a hospital in Prague, recovering from her ordeal, she rejoined the diplomatic corps. She was serving with the Czech consulate in Cleveland in 1948 when Czech communists, with the support of Soviet forces, took complete control of her country. At that point, she asked the United States for political asylum. She became a citizen of the United States in 1957.

Miss Manhal had been active in the American Sokol Organization, the Czechoslovak National Council of America, and the Czechoslovak Society of Arts and Sciences.

She leaves no immediate survivors.
