Albert A. Peter, 84, who retired in 1962 as assistant general counsel to the comptroller general of the General Accounting Office, died Monday at his home in Washington. He suffered from a heart ailment.

Mr. Peter was born in Leopold, Ind. He came to Washington from Tell City, Ind., in 1917 to work in the office of audit at the Treasury Department. He remained with that office when it was taken over by the newly established GAO in 1921.

He attended night classes at National University Law School, where he earned bachelor's and master's degrees in law and patent law. He was admitted to practice before the U.S. Supreme Court.

Mr. Peter was a member of the Fourth Degree Washington Assembly of the Knights of Columbus and also was state deputy for the District of Columbia and Panama. He was faithful navigator for the Fourth Degree K and C and grand commander and regional director of the Alcantara Caravan of the Alhambra.

He was active in St. Ann's Catholic Church and was a member of the Federal Bar Association and the Oldest Inhabitants of D.C.

He is survived by his wife, Martha, of the home; four children, Bernice Alexander, of Port St. Lucie, Fla., Mary Margaret Chicca, of Hyattsville, Maurice A., of Baltimore, and Albert A. Jr., of Seattle; a brother, August E., of St. Louis; a sister, Bertha Ward, of Tiffin, Ohio, 21 grandchildren and 10 great-grandchildren.

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