Aurelia D. Mayer, 60, chief physical therapist at the Child Development Center of Northern Virginia and its predecessor, the Cerebral Palsy Development Center of Northern Virginia, for more than 20 years, died of cancer Friday at her McLean home.

Mrs. Mayer, a registered nurse and clinical physiotherapist, also provided volunteer services to a number of local centers for crippled children and adults.

She began her career at Northwestern University in 1945, after completing postgraduate work there in physical therapy. She had earned a nursing degree from St. Joseph's Hospital school of nursing in Chicago in 1942.

The results of her work at Northwestern as a technical assistant to Dr. Stafford Osborne was published in the Archives of Physical Medicine.

Mrs. Mayer had worked as a physical therapist since moving to this area in 1950. She joined the Cerebral Palsy Development Center in 1957 and retired in 1978 for health reasons.

She was the subject of a number of local newspaper articles for her role as a volunteer physical therapist with such organizations as the Northern Virginia Crippled Children's Clinic, the Visiting Nurses Association and the D.C. Society for Crippled Children and Adults.

Mrs. Mayer was born in Latrobe, Pa. She was a member of St. John's Catholic Church in McLean and sang in the church's choir for several years. c

Survivors include her husband, Ralph G., of McLean; her mother, Florence Meloy of Latrobe; a sister, Kay Janis of Lake of the Woods, Va.; two brothers, Urban Meloy of Chicago and Thomas Meloy of Kansas City, Kan.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
