Jean S. Hooper, 98, who did volunteer work at the Common Cause public-interest lobbying group for more than 25 years, died Sept. 27 at her home in Arlington County.

She had cancer, said her daughter Sacie Lambertson.

Jean Elizabeth Shattuck was a native of Ashland, Kan., and a 1936 graduate of Washburn University in Topeka, Kan. She was then hired by the Kansas Works Progress Administration to assist with employment programs in southwest Kansas for two years during the Depression.

She accompanied her husband on his military assignments in South Korea and Germany before settling in Arlington in 1954.

She was a member of the Seymour Club, a scholarly women’s group.

Her husband of 46 years, retired Army Col. Melvin Hooper, died in 1985. Their daughter Katherine McGregor died in 2001.

Survivors include four daughters, Sacie Lambertson of Winchester, Kan., Susan Belle of Arlington, and Jean Hnylka and Mary Hooper, both of Montpelier, Vt.; a brother; a sister; 14 grandchildren; and 11 great-grandchildren.
