Kathleen Scofield "Katie" Louchheim, 87, a poet, author, former deputy assistant secretary of state and director of women's activities for the Democratic National Committee, died of pneumonia and complications related to a stroke Feb. 11 at her home in New York City.

Mrs. Louchheim, who lived in Washington from 1934 until the early 1980s, also was a former United Nations official who served during World War II as deputy director of public information for the United Nations Relief and Rehabilitation Administration. After the war, she interviewed displaced people in Germany for the agency. In 1968 and 1969, she was U.S. ambassador to UNESCO.

She was energetic and well-connected politically, with a reputation for a sunny disposition, a quick wit and an engaging smile, and she had a network of influential friends, whom she wrote about in a chatty reminiscence, "By the Political Sea," published in 1970. The book was an account of Mrs. Louchheim's friendships with the likes of Presidents Truman, Kennedy and Johnson; former vice president Hubert H. Humphrey; Sen. Eugene McCarthy (D-Minn.); former first lady Bess Truman; former secretary of state Dean Acheson; and Adlai Stevenson, the Democratic presidential nominee in 1952 and 1956. In 1956, Mrs. Louchheim accompanied Stevenson on his campaign.

Her other books included a collection of poems, "With or Without Roses," published in 1966, and a story of Mrs. Louchheim's early years in Washington, "The Making of the New Deal: The Insiders Speak," published in 1983. She also wrote frequently for The Washington Post and other publications.

A native of New York, Mrs. Louchheim studied in Europe as a young woman and attended Columbia University. In 1926, she married Walter C. Louchheim Jr., a banker who came to Washington in the early years of the Roosevelt administration to help organize the Securities and Exchange Commission. He died in 1973.

As a newcomer to Washington, Mrs. Louchheim began spending time in the public galleries of the Senate and House to watch legislation being passed, then in the Supreme Court, where much of it was challenged. She also began working as a volunteer at the Democratic Party's national headquarters, and by 1940 was serving on the party's national finance committee. She joined the staff of the Foreign Relief and Rehabilitation Operations in 1942, and the next year helped organize the United Nations Relief and Rehabilitation Administration.

She was a delegate to the Democratic National Conventions of 1948 and 1952, a member of the D.C. Democratic Central Committee and an alternate Democratic national committeewoman from the District of Columbia. She campaigned vigorously for the right of District of Columbia residents to vote in presidential elections.

In 1953 she was named director of women's activities for the Democratic National Committee, a job she held until 1960. In this assignment she specialized in organizing and fund-raising, including "Teas for TV," to help cover the cost of television appearances by Democratic candidates.

From 1956 to 1960, Mrs. Louchheim also served as vice chairman of the Democratic National Committee. She traveled extensively in these jobs, covering more than 200,000 miles on behalf of Democratic candidates and party business.

When she was named deputy assistant secretary of state for public affairs in 1962, Mrs. Louchheim was the highest woman official in the history of the State Department. She resigned as ambassador to UNESCO in 1969, calling the job a sinecure.

In 1981, Mrs. Louchheim married Donald S. Klopfer, a founder and chairman emeritus of Random House Inc. He died in 1986.

Survivors include two daughters, Mary Louchheim Evangelista of New York City and Judith Louchheim Read of Darien, Conn.; three grandchildren; and three great-grandchildren.
