Correction: A previous version of this obituary incorrectly reported that Isabelle Yount lived in Potomac and Columbia. She was a longtime resident of Washington.

Isabelle H. Yount, a longtime elementary school teacher who taught in the D.C. public schools for 36 years, died Sept. 1 at the Washington Home and Community Hospices. She was 96.

The cause was congestive heart failure, said her half sister, Doris Wright.

Miss Yount, a longtime Washington resident, taught special education at the old Military Road School from 1966 until her retirement in 1977. Earlier, she was primarily a first-grade teacher at a number of Washington schools, including Brookland, Emery, Bruce-Monroe and the now-defunct Gage-Eckington elementary schools.

Isabelle Henkel Yount was born in Newton, N.C. She was a 1939 graduate of the old Wilson Teachers College in the District and received a master’s degree in education from George Washington University in 1953. She pursued advanced studies in special education at Philadelphia’s Temple University.

She did volunteer work at Forest Haven, a former children’s rehabilitation center in Laurel; for the National Children’s Center, an organization that assists children with developmental disabilities; and for other educational and social service groups.

Survivors include a half sister, Doris Wright of the District, and a half brother, Charles Leslie Jr. of Falls Church.
