Alvin Reiner, an electrical engineer and specialist in land mobile radio services who worked for the Federal Communication Commission, died Dec. 8 at Holy Cross Hospital in Silver Spring. He was 90.

The cause was congestive heart failure, said his wife, Barbara Reiner.

Mr. Reiner, a Silver Spring resident, spent the majority of his career at the FCC and served as a branch chief. He retired in 1990 as senior technical adviser of the Office of Engineering and Technology’s authorization and evaluation division.

Alvin Reiner was born in the Bronx, N.Y., and raised in Lewistown, Pa. He was a 1950 electrical engineering graduate of Pennsylvania State University. He served in the Army Signal Corps in Europe during World War II and landed at Omaha Beach within weeks after the Normandy invasion, his family said.

He was a past Washington chapter president of the Institute of Electrical and Electronic Engineers, and his memberships included Jewish War Veterans.

Survivors include his wife of 62 years, Barbara Schiffman Reiner of Silver Spring; three children, Andrew R. Reiner of Cheverly, Matthew S. Reiner of Silver Spring and Leah Chava Reiner of Williamsburg, Mass.; a sister; five grandchildren; and one great-grandson.
