Silas Little 67, a federal aviation official for more than 30 years who specialized in radio navigational aids, died Tuesday at the Veterans Administration Hospital in Martinsburg, W. Va., of amyotrophic lateral sclerosis, "Lou Gehrig's disease."
Mr. Little was born in Helena, Mont., and began his government career in 1935 with the old Bureau of Air Commerce in the Commerce Department in Nevada. He had numerous assignments in the western United States and in Hawaii before being transferred here in 1952. By then, he worked for the Federal Aviation Administration.
In 1960, he went to Cairo for the Agency for International Development. He also worked in Bangkok, Thailand, and Taiwan before returning to Washington. He retired in 1973 for reasons of health.
Mr Little and his family had established a home in Falls Church in 1958 and maintained it through the years of his overseas assignments.
He was a member of the Society of Military Engineers, and other professional groups. His other interests included numismatics and he published a book on the banknotes of Thailand.
Survivors include his wife, Joan Anthony Little, and a daughter, katherine Andrea, both of the home, and another daughter, Patricia Joan Augeri, of Springfield.
The family suggests that expressions of sympathy be in the form of contributions to the Amyotrophic Lateral Sclerosis Society of America, 15300 Ventura Blvd., Suite 315, Sherman Oaks, Calif., 91403.
