Leif Oxaal, 77, an association management consultant who once headed the Glass Container Manufacturers Institute in Washington, died of pneumonia June 8 at Virginia Hospital Center-Arlington. He lived in Annandale.

The Norwegian-born World War II and Korean War veteran began his career in the trade association industry in the early 1950s when the Plumbing Fixture Manufacturers Association in Washington hired him as its technical director.

He went on to be executive director of the Packing Machinery Manufacturers Institute from 1964 to 1972. During his tenure, he helped build one of the largest industrial trade shows in the country and launched an international trade program, which included assisting Latin American packaging industries to organize national trade associations.

In 1972, he was named president of the Glass Container Manufacturers Institute, now the Glass Packaging Institute. In that capacity, he oversaw the relocation of the association's headquarters from New York to Washington. He left his job after about a year to cross the Atlantic Ocean on a 32-foot sailboat. When he returned to the Washington area after his trip, he became a consultant in association management.

Among his projects as a consultant was developing an attendance promotion plan for associations.

Born in Nordfjordeid, Norway, Mr. Oxaal immigrated to the United States with his family when he was 12 years old. He grew up in Galion, Ohio, and attended the University of California at Los Angeles and Baldwin-Wallace College in Berea, Ohio.

He served in the Royal Norwegian Air Force during World War II and the U.S. Army during the Korean War. In the latter conflict, he was assigned to psychological warfare operations.

Mr. Oxaal was a member of the board of the Norwegian Society of Washington; a past board member of the National Center for Resource Recovery in Washington; and chairman of a National Science Foundation two-year study on industrial innovation and federal policy.

His marriage to Barbara Oxaal ended in divorce.

Survivors include his wife of 18 years, D'Ann Taflin of Annandale; three children from his first marriage, Ford Oxaal of Cohoes, N.Y., Kristine Keesey of Rockville and Karin Oxaal of Columbia, Mo.; two sisters, Aase Stinson of Fort Lauderdale, Fla., and Ingrid Oxaal of Reston; a brother, Ivar Oxaal of Hull, England; and six grandchildren.
