Rudy Bergstein, 85, an artist and photo interpretation analyst who retired in 1982 from the Defense Intelligence Agency, died Feb. 18 at the Beaverbrook Corner Assisted Living Facility in Columbia. He had Alzheimer's disease.

Mr. Bergstein, who lived in Columbia, was born in New York. He was a prize-winning freelance commercial artist and painter before he came to Washington and became a draftsman with the Agriculture Department in 1940. During World War II, he served with the Army Air Forces and did aerial photographic work and drafting.

After the war, he was a cartographer and photo interpreter with the Army Map Service and the Naval Photo Interpretation Center before he transferred to the DIA. He received a citation from President John F. Kennedy for his work during the Cuban missile crisis.

He was a member of the men's club at Congregation Har Tzeon-Agudath Achim and designed its chapel. He served as a Cub Scout leader in Wheaton.

In his youth, Mr. Bergstein played the violin, including a solo performance at New York's Carnegie Hall at age 8. As a young man, he gave flying lessons and was a lifeguard, an amateur boxer and a weight lifter.

Survivors include his wife of 60 years, Dorothy W. Bergstein of Columbia; three sons, Steven, of Gaithersburg, Nathan, of Columbia, and David Robin Bergstein of Rockville; and a daughter, Gale Lynn Berkowitz of Reistertown.
