Col. Sanderson was a member of the New York Avenue Presbyterian Church in Washington.

His decorations include the Legion of Merit.

Col. Sanderson was a native of Kansas. He was a graduate of the University of Nebraska's college of engineering and a 1946 graduate of the Command and General Staff College.
