George B. Kennedy Sr, 85, a retired vice president for sales of the R. P. Andrews Paper Co. here and who later became an executive of a trade organization, died of congestive heart failure Sunday at the Veterans Administration Hospital in Perryville, Md. He had been in the hospital about four years for treatment of arteriosclerosis.

Mr. Kennedy was born in Melrose, Mass., moved to Washington as a boy and graduated from Central High School. During World War I, he served in the Army in France and then went into the printing and advertising business.

Until the mid-1930s, he headed the H -- K Advertising Company. He then joined the R. P. Andrews firm. He took leave to serve as a Red Cross field director in Italy during World War II. He was vice president for sales for Andrews when he retired in 1963.

For the next five years, he was the Washington representative of Sales and Marketing Executives-International, a trade association, based in New York City.

From 1921 until he moved to the hospital, Mr. Kennedy was a resident of Takoma Park, where he served for several years on the City Council.

He was a past-master of the Congress Masonic Lodge and a member of the Veterans of World War I, the American Legion and the Veterans of Foreign Wars. He was a member of the Cleveland Park Congressional Church in Washington and an associate member of the Pilgrim Congregational Church in Harwichport, Mass., where he maintained a summer home.

Survivors include his wife, Emma F., of Takoma Park; two daughters, June Scopeletis of Washington, and Natalie Burkhart of Cheverly; six grandchildren, and nine great-grandchildren. A son, George B. Jr., died on Feb. 27.

The family suggests that expressions of sympathy be in the form of contributions to the Renewal Fund of the Cleveland Park Congressional Church, or to the Pilgrim Congregational Church, Harwichport, Mass.
