Eugene B. Bruns, 84, who retired in 2003 as chairman of Southeast Asian programs at the Foreign Service Institute in Arlington, died Jan. 10 at Collington Episcopal Life Care Community in Mitchellville.

He had complications from Alzheimer’s disease, said his daughter H. Jordan Richards.

Mr. Bruns worked at the Foreign Service Institute, a training institution of the federal government, for three decades. He had previously worked in Washington for the U.S. Foreign Service and the U.S. Agency for International Development.

Eugene Benson Bruns was a Baltimore native and received a bachelor’s degree in foreign affairs from the University of Virginia in 1953.

He was a resident of the Hollin Hills neighborhood near Alexandria and a past president of the board of trustees of the Northern Virginia Fine Arts Association, his daughter said.

His wife of 45 years, Caroline “Chase” Lane Bruns, died in 2006. Survivors include three children, H. Jordan Richards of Alexandria, Emerson E. Bruns of New York City and S. Lane Bruns of Annapolis; a brother; a sister; and three grandchildren.
