Robert T. Moore, a lawyer with the Justice Department’s Civil Rights Division, died Jan. 29 at his home in Washington. He was 76.

The cause was arteriosclerotic cardiovascular disease, said his son Robert Moore.

Mr. Moore joined the Justice Department in 1963, and his early assignments included enforcing voter registration laws in Mississippi and Louisiana.

His work also involved desegregation of the police, fire and parks departments in Chicago and negotiating the 1974 consent decree between the United Steelworkers union and the steel industry. He retired about 20 years ago.

Robert Thompson Moore was born in Dallas. He graduated in 1959 from Duke University in Durham, N.C., and in 1962 from the University of Texas law school.

He was a 50-year resident of Capitol Hill.

His first marriage, to Linda Turman, ended in divorce. Survivors include his wife since 1996, Helen Riskevich Moore of Washington; two children from his first marriage, Francie Moore of Los Angeles and Robert Moore of Washington; a son from his second marriage, Sergei Moore of Washington; and three grandchildren.
