Gwyneth Dunn, a home and hospital teacher for Prince George’s County Public Schools who taught children who were ill at home or in hospitals for extended periods of time, died Jan. 10 at the Riderwood retirement community in Silver Spring. She was 86.

The cause was chronic obstructive pulmonary disease, said her daughter, Reinette Schneider.

Gwyneth Mary Davies was a native of Utica, N.Y., and settled in the Washington area after graduating in 1948 from the College of Wooster in Ohio. Starting in the early 1960s, she worked for Prince George’s County schools for more than 30 years.

She was a member of Riverdale Presbyterian Church in University Park, Md., where she was an elder and deacon and sang in the choir. She was a longtime New Carrollton resident but had spent the past nine years at Riderwood.

Her husband, Stanley N. Dunn, whom she married in 1951, died in 2004. Survivors include four children, Catherine Collins of Winston-Salem, N.C., Reinette Schneider of Woodbridge, Va., Stanley N. Dunn Jr. of Green Village, N.J., and Michael Dunn of Adamstown, Md.; a sister; seven grandchildren; and seven great-grandchildren.
