Jeanne Marie Rapp, 57, a former D.C. public school teacher who was active in church and hospital groups, died of cancer Wednesday at Walter Reed Army Medical Center.

Mrs. Rapp, who was born in Washington, graduated from the Country Day School of the Sacred Heart in Bethesda and Manhattanville College in New York.

She and her husband, Navy Cmdr. William A. Rapp, lived in San Diego, Calif., before his death in 1953.

Mrs. Rapp then returned here. In the late 1960s and early 1970s, she taught in D.C. public schools.

She was a member of the Women's Guild at Georgetown University Hospital and a volunteer in the hospital's gift shop. She also was a member of the parish of the St. Thomas the Apostle Catholic Church in Washington and was a president of the church's Home and School Association.

Survivors include two sons, William Anthony III of Silver Spring, and James A., of Washington; a twin brother, Dr. Robert J. O'Donnell of McLean; five other brothers, Msgr. William F. O'Donnell of Greenbelt, Dr. Vincent Lane and John Jude O'Donnell, both of Bethesda, Hugh L. O'Donnell of Buffalo, and Paul A. O'Donnell of Washington, and two grandchildren.
