Elizabeth Richards Schaub, 69, a longtime area resident who was active in cultural groups, died of cancer Tuesday at Georgetown University Hospital. She was a resident of Washington.

Mrs. Schaub was a native of Urbana, Ohio, and graduated from Denison College in Granville, Ohio, with a degree in literature. In 1938, she married Robert Kenneth Richards, and moved to Washington three years later. Mr. Richards died in 1969.

In 1978, she married William Fulton Schaub, a former under secretary of the Army under President John Kennedy.

Mrs. Schaub was a volunteer with the National Symphony Orchestra and the Friends of the Kennedy Center. She was a member of the board of directors of the American Kidney Fund, and was a member of the D.C. Commission for Education. She also was active with the PTA in Washington, and had tutored for several years at the Kingsbury Center for Education in Washington.

In addition to her husband, survivors include a daughter, Susan Richards Shreve; a son, Jeffrey Greene Richards, and a stepson, William C. Schaub, all of Washington, and six grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Washington Cathedral, Washington, D.C.
