Chris Boykin, 52, an electronics engineer with the Harry Diamond Laboratories and a part-time professor at the University of the District of Columbia, died of a liver ailment Thursday at his home in Washington.

Mr. Boykin had worked for the nuclear effects laboratory of the Harry Diamond complex for the last 25 years. He had taught at UDC and the old Federal City College for about eight years.

He had received several outstanding achievement awards for his work at the Harry Diamond Laboratories.

Mr. Boykin was a native of Garland, N.C. He attended Shaw University in Raleigh, N.C., and graduated from the Howard University school of engineering. He served with the Army in Korea during the conflict there and had lived in Washington since 1953.

He was a Past Worshipful Master of the James H. Hill Lodge No. 16 of the Masons.

Survivors include his wife, Geraldine P., a daughter, Jeanetta, and his mother, Mrs. Ronnie I. Boykin, all of Washington; four sister, Mary Lisa Anderson of Garland, N.C., Marie Ware of Norfolk, and Ronnie Boykin and Anne Butler, both of Washington, and four brothers, James, of Poughkeepsie, N.Y., and Amos, E.J., and Earl, all of Washington.

The family suggests that expressions of sympathy be in the form of contributions to the United Negro College Fund.
