Louise Woolfolk Black, 82, the widow and mother of Army colonels and a resident of Gibson Island, Md., for the last 30 years, died Thursday at Walter Reed Army Hospital after a stroke.

She was a member of the Gibson Island Golf Group and the Gibson Island Garden Club. She was an accomplished bridge player. Mrs. Black was a member of the Altar Guild of St. Christopher's By-The-Sea Chapel at Gibson Island.

Mrs. Black was a native of Pittsburgh and attended Mount Vernon College. She was the widow of Ira W. Black, a retired Army colonel, who died in 1968. Mrs. Black had accompanied her husband on tours in this country and the Philippines. She also had toured China and Japan in the 1930s.

Survivors include two sons, Army Lt. Col. Ira W. Black Jr. of Fort Hood, Tex., retired Army Col. Robert W. Black of Potomac; two daughters, Carolyn B. Underwood of Danville, Calif., and Nancee W. Black of Washington; a sister, Mary W. Norton of Massachusetts, and seven grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the St. Christopher's By-The-Sea on Gibson Island, or the Johns Hopkins Research Foundation c/o Johns Hopkins Hospital in Baltimore.
