Joseph H. Giebel Sr., 89, who retired in 1957 after more than 20 years as manager of the Washington branch of the Mack Truck Co., died of pneumonia Tuesday at the Chevy Chase Convalescent Home, where he had been a resident for about 1 1/2 years.

A native of Washington, Mr. Giebel had been well known in athletic circles. He played catcher for the Kansas City Blues for about five years and also played with the Philadelphia Athletics. He played football and baseball with the Rex A.C. and the Twining Athletic Club, sandlot clubs in the Washington area.

Mr. Giebel served with the American Red Cross in World War I. He was a stenographer with the Navy Department after the war.

He was active in the Holy Name Society of St. Ann's Catholic Parish in Washington.

His wife, Vernell H. Giebel, died in 1967. A daughter, Dorothy M. Hanlon, died last year.

Survivors include two sons, Joseph H. Jr., of Annapolis, and Richard A., of Bethesda; a brother, Adam, of McLean; a sister, Rose Curtin of Lutherville, Md., 12 grandchildren and seven great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Little Sisters of the Poor in Baltimore.
