Horace H. Robbins, 73, an administrative law judge at the Social Security Administration since 1955, died of cancer June 30 at his home in Silver Spring.

Judge Robbins, who was born in New York City, earned bachelor's and law degrees at Columbia University. He began his federal career as a lawyer with the Department of Agriculture in New York. After World War II service in the Navy, he moved to Washington and returned to Agriculture.

He later was a lawyer in the Justice Department, at the Office of Price Stabilization and at the Department of the Army. When he joined the Social Security Administration, he was assigned to its Philadelphia office. In 1960, he was transferred here. He never retired.

In the late 1960s, Judge Robbins was loaned to the Office of Education in the old Department of Health, Education and Welfare. He conducted hearings on school districts in Mecklenburg County, N.C., Jackson, Miss., and Ferndale, Mich. The government claimed the school districts should be denied federal funds, alleging policies of racial segregation.

In 1974, Judge Robbins published a book, "Fictive Capital and Fictive Profit. The Welfare-Military State: The Political Economy Based on Economic Fictions." He was a member of the Humanist Society.

His marriage to Louise Robbins ended in divorce.

Survivors include two children, Anne Robbins of Brooklyn and Mark Robbins of Silver Spring, and a stepson, Louis Robbins of Washington.
