Harry Koenick, 70, who realized one of his last desires when he had his formal bar mitzvah last December, died of cancer Friday at the Veterans Administration Hospital here.

A standing-room-only crowd of 600 joined in the community celebration at Ohr Kodesh Congregation in Chevy Chase on Dec. 11.

Although his bar mitzvah was 57 years late, it was noted then that Mr. Koenick had been a "responsible member of the adult Jewish Community" here for many years.

He had sounded the ram's horn or shofar during the High Holy Days and had chanted from the Torah during worship since 1949.

Mr. Koenick had missed having his bar mitzvah at the traditional age of 13 because of the turmoil in Europe following World War I.

He was born in Shatsk, about 40 miles from Minsk in Russia in 1906. His father emigrated to this country a few years later and his mother died of typhoid in 1919.

Mr. Koenick fled to America with other members of his family in 1920, coming to Washington to join his father, who was a tailor.

He worked at various jobs and then after the end of prohibition became manager of a liquor store operated by his brother-in-law, Sam Eig, at Kennedy Street and Georgia Avenue NW.

Mr. Koenick retired in the late 1950s from the store. He then owned several coin-operated laundry machines in stores and apartment houses in this area until retiring a year ago.

He was active in B'nai B'rith and the Jewish Community Center.

He is survived by his wife, Adeline, of the home in Chevy Chase; three daughters, Judith, of the home; Janet Volat, of Silver Spring, and Ruth Ann, of St. Petersburg, Fla.: a brother, Stanley, of Gaithersburg; a sister, Frances Horowitz, of Silver Spring, and four grandchildren.
