Alloyce Robinson Tucker, 79, a teacher, activist and wife of civil rights leader Sterling Tucker, died June 9 at ManorCare in Washington of pneumonia after a heart attack.

Mrs. Tucker was born in Akron, Ohio, and received a bachelor's degree from Akron University, where she was the first black woman to become a member of the student council, a member of the May queens court and winner of a collegiate oratorical contest.

She married her college sweetheart, and two years later the couple had their first child, born a day after Mrs. Tucker received a second bachelor's degree. She also received a master's degree in sociology from Akron University in 1952.

Mrs. Tucker began her teaching career in 1949 in Akron and taught in Canton, Ohio, after the family moved there in 1955. In Canton, she developed a new report card system for the primary grades that was adopted throughout the school system.

The Tuckers moved to Washington in 1957, when her husband became director of the Washington Urban League. She taught at Powell Elementary School in the District until 1961, when she resigned to devote herself to her family and to assisting her husband in his civil rights and political career.

Mrs. Tucker was part of the official city delegation that received visiting foreign heads of state during Mayor Walter E. Washington's tenure. She also participated in the 1960s civil rights demonstrations and was known, her husband said, for her warm disposition and her interest in and enjoyment of others.

Mrs. Tucker was a member of many organizations, including Alpha Kappa Alpha sorority, and she served on the board of Children's Hospital. She was a member of the Urbanite Guild of the Washington Urban League, and of Trinity Episcopal Church in the District.

Survivors include her husband of 56 years; two daughters, Shelly Jeffery of Washington and Lauren Tucker of New York; a sister; and three grandsons.
