Linda Leaird Ittner 45, an assistant staff director of the House Select Committee on Children, Youth and Families who worked on Capitol Hill for the last 11 years, died of leukemia Oct. 12 at the University of Maryland Hospital in Baltimore. She lived in Columbia.

She spent her career on the Hill working with Rep. Patricia Schroeder (D-Colo.). Mrs. Ittner was a legislative asistant on Schroeder's personal staff and also worked on the staff of the civil service subcommittee of the Post Office and Civil Service Committee.

Schroeder said in a statement after Mrs. Ittner's death, "Linda had a major legislative impact on laws concerning women's rights, child abuse, pension rights, and employment."

Mrs. Ittner was a native of Fort Lauderdale, Fla., and a graduate of Salem College in North Carolina. Before moving here in 1971, she worked for the overseas board of the United Presbyterian Church and served on the church's administrative staff in New York.

She was active in the interfaith center in Columbia and was a member of the Sandy Spring Friends Meeting. She also was a member of the Howard County Peace Action Committee.

Her marriage to Dr. Richard E. Ittner ended in divorce.

Survivors include two children, Richard E. Jr. and Deborah Jane Ittner, both of Columbia.
