Lucille Williams Bridges, 57, who taught social studies in the D.C. public schools for nearly 25 years, died of cancer Monday at Howard University Hospital.

Mrs. Bridges began her career in the D.C. schools in 1955 at Eliot Junior High School. In 1961, she transfered to MacFarland Junior High and two years later joined the faculty at Backus Junior High.

She was on the faculty of Woodrow Wilson Senior High School from 1970 until retiring in 1979. She also had been a content coordinator for "Afro-American Perspectives," a television series in the mid 1970s. The series was produced by the Maryland State Department of Education.

Mrs. Bridges was a life member of the National Education Association, the Capital Press Club and the D.C. Teachers Union. She was a founder and first president of the D.C. Council for Social Studies.

A member of the Asbury Methodist Church in Washington for more than 30 years, she had edited the church paper. "The Asburyan," for 13 years and had been a member of both the Weseleyan Choir and the United Methodist Church Women.

Mrs. Bridges was born in Hamilton, Va., and reared in Washington. She was a 1941 graduate of Dunbar High School and earned undergraduate and law degrees at Howard University. In 1970, she earned a master's degree in teaching at the State University of New York at Buffalo.

Survivors include her husband, Stanley P. Bridges Jr. of Washington, a son, Stanley Jr., of Pittsburgh; two sisters Edna W. McClellan and Madlyn W. Calbert, both of Washington, and a brother, Eugene M. Williams of Suitland.

The family suggests that expressions of sympathy be in the form of contributions to the Howard University Scholarship Fund.
