Lewie V. Gilpin, 67, a retired vice president of the Hill & Knowlton public relations firm and a former newspaperman and radio broadcaster and producer, died Sunday at his home in Alexandria following a heart attack.

Mr. Gilpin, who was born in Tracy, Minn., attended the University of Minnesota and earned a bachelor's degree from the School of Journalism at the University of Missouri. In 1937, he moved to Washington and became a correspondent for a group of newspapers in the Carolinas. A year later, he joined Broadcasting Magazine as a reporter.

During World War II, Mr. Gilpin was an information specialist with the old War Department and then was commissioned in the Army Air Force. He saw duty in Florida and British Guiana.

After the war, he was a reporter here for newspapers in North Carolina until 1948, when he joined the Washington news bureau of the National Broadcasting Company. During his years with the network, Mr. Gilpin was a writer, a producer and a broadcaster for its "Three-Star Extra" radio news program.

In 1957, he left broadcasting and joined Hill & Knowlton. He managed accounts involving steel, space and transportation. Because of his wide contacts in the media, he frequently acted as a spokesman on company accounts outside of his own area of specialization. He was a vice president of Hill & Knowlton when he retired in 1976.

Mr. Gilpin was a member of the White House Correspondents Association, the Congressional Press Galleries, the Army & Navy Club, the Public Relations Society of America, the National Press Club and the Belle Haven Country Club, where he played golf. He also was a member of Christ Episcopal Church in Alexandria. He was a former president of the Yates Gardens Citizens Association and the Parent-Teacher Association of Lee Elementary School, both in Alexandria.

Survivors include his wife, Mary Jane, of Alexandria; a son, Lewie V. Jr., also of Alexandria; one brother, Jon Gilpin, of Springfield, Ill.; two sisters, Gladys Gilpin, of Tracy, and Genevieve Schentzel, of St. Cloud, Minn., and one granddaughter.

The family suggests that expressions of sympathy be in the form of contributions to St. Stephen's School, Alexandria, Va.
