Allan L. Kamerow, 81, a trial lawyer who had practiced in Washington for more than a half-century, died of pneumonia Dec. 27 at the Washington Hospital Center. He lived in Alexandria.

He and his brother, Stanley, founded the law firm of Kamerow & Kamerow in the District in 1946 and continued the partnership until Stanley Kamerow's death in July.

Allan Kamerow, a World War II Army veteran, was born in Baltimore and raised in Washington. He graduated from Roosevelt High School and Catholic University law school and was admitted to the D.C. Bar in 1943.

Mr. Kamerow, who had lived in Alexandria since 1952, was a founding president of its Sterling Citizens Association and past president of the Seminary Hills Citizens Association. He had served on the Alexandria Planning Commission from about 1970 to 1990.

He was a past president of the Agudas Achim Congregation in Alexandria. As a member of the Jewish Community Center, he had helped found the Jewish Lions Club in the 1930s.

Mr. Kamerow, whose hobbies included golf, was a member of Westwood Country Club and was a 50-year Washington Redskins season ticket holder. As a young man, he had parlayed his hobby of playing spoons into an appearance with the Tommy Dorsey Orchestra. In the 1970s, as a ham radio operator, he relayed emergency messages from missionaries in Liberia during a revolution there.

Survivors include his wife, Betty Clayman Kamerow, whom he married in 1948 and who lives in Alexandria; a son, Douglas, of Chevy Chase; a daughter, Frances Kamerow Hamberger of Springfield; two brothers, Norman and Martin, both of Bethesda; a sister, Evelyn Sachs of Chevy Chase; and five grandchildren.
