An obituary in Saturday's editions of The Washington Post about Lawrence David Low, 64, who died Monday, failed to include the cause of his death. He had emphysema.

Lawrence David Low, 64, a retired official of the old Atomic Energy Commission, died Monday at the National Naval Medical Center in Bethesda.

Mr. Low was director of the AEC's inspection and enforcement division., the division of compliance, from 1960 until his retirement in 1972.

The functions of this division were transferred to the Nuclear Regulatory Commission when it was established and the AEC abolished in 1974.

Mr. Low joined the newly created AEC in 1947 as an inspection specialist. He served as director of the security division of the Savannah River Operations in South Carolina from 1950 to 1956 and was assistant chief of Washington area security operations before being named director of compliance division.

He received the AEC's superior performance award twice.

He began his government career in 1937 as a messenger for the Interstate Commerce Commission. He subsequently served as a security officer for the state Department, as a legal consultant for the Veterans Administration and as a Civil Service Commission inspector before joining the AEC.

After retiring, Mr. Low was a vice president and served on the board of directors of the Nuclear Surveillance and Auditing Co. in Falls Church.

A retired Naval Reserve officer, he served as a Navy intelligence officer in Europe during World War II.

He was born in Butler, Pa., and reared in Rock Creek, Ohio. In 1941, he earned a law degree from National University School of Law, now part of George Washington University. He lived in Damascus.

Survivors include his wife, the former Elinor Boterweg of Damascus; three sons, Thomas A., of Greensboro, N.C., Robert C., of Ijamsville, Md. and Michael D., of Damascus; three sisters, Edith Miklacic of Rock Creek, Ohio, Elizabeth Low of Los Angeles, and Margaret Chandler of Painesville, Ohio; two brothers, Arthur and Francis Low, both of Anaheim, Calif., and two grandchildren.
