Morton B. Levin, 65, a former administrator and program coordinator for the old U.S. Information Agency who was assigned to Vietnam and Thailand before retiring in 1972, died of cancer Friday at Suburban Hospital. He lived in Chevy Chase.

Mr. Levin joined the USIA's International Press Service shortly after the agency was established in 1953. He was active in USIA's People to People program and was a special assistant and supervisory information specialist before being sent to Vietnam in 1965 as a foreign information officer. In 1971-72, he was the USIA executive officer in Bangkok, Thailand. He received the Distinguished Service Award from the USIA, which became the International Communication Agency in a reorganization in 1977.

A federal employe for 33 years, he began his federal service in 1939 as a budget analyst with the National Youth Administration, a New Deal agency that provided work training for unemployed youth. He served in the Army Air Forces in World War II and then joined the Navy Department. He later worked for the old National Housing Agency and the State Department before joining USIA.

Mr. Levin was born in Philadelphia and earned a bachelor's degree from Morris Harvey College in Charleston, W.Va.

He was a past-president of the Men's Club of Adas Israel Congregation here and had been active in scouting.

Survivors include his wife Mildred of Chevy Chase; three sons, Howard of San Jose, Calif., Kenneth of Atlanta and Robert of Brookline, Mass.; two brothers, Joseph of Montgomery, Ala., and Harvey of Falls Church, and a grandchild.

The family suggests that expressions of sympathy be in the form of contributions to Adas Israel Congregation in Washington, the American Cancer Society or the Montgomery County Chapter of the Visiting Nurse Association.
