Arthur L. Prahinski, 74, who retired in 1969 as a cataloging specialist for the Department of the Army, died of emphysema Wednesday at St. Joseph's Manor in Meadowbrook, Pa., where he had been living since December.
Mr. Prahinski was a cataloguing specialist for several government agencies before joining the Army Quartermaster Corps in the 1930s. During World War II, he implemented a numbering system for all purchases by the Quartermaster Corps. This system later was Numbering System used by the government.
In 1948, he moved to Washington and transferred to Army Materiel Command headquarters, from which he retired in 1969 as a catalogue supply specialist.
Mr. Prahinski was born in Spokane, Wash., and served in the Navy from 1923 to 1927.
He was active in the Shrine of the Most Blessed Sacrament Catholic Curch here and was a member of the choir, the Holy Name Society and the Loyola Retreat League.
Survivors include his wife, the former Dorothy R. Killian, of Washington; eight children, Sister Dorothy Rose, of Meadowbrook, Nancy M. Obold, of Rockville, Mary Jane, of Hyattsville, Rita M. Kinger, of College Park, Theodore, of Washington, Arthur L. Jr., of Bethesda, Leo F.X., of Glenn Dale, and Robert J., of Phoenix, Ariz.; two sisters, Olga Dumont, and Maria Schade, both of Los Angeles, and 12 grandchildren.
The family suggests that expressions of sympathy be in the form of contributions to the Sisters of the Holy Redeemer, St. Joseph's Manor, Meadowbrook. CAPTION: Picture, ARTHUR L. PRAHINSKI
