Scott Tanner retired after more than 30 years with the Federal Aviation Administration, working as an Air Traffic Safety Inspector for the final 13 years of his career. A lifelong railroad enthusiast, Tanner's interests gravitated toward railroad history and artifacts. Rather than developing an expertise with railroad operations, he is far more interested in railroad advertising and promotion, specifically that of the Great Northern Railway.
Tanner has published articles on a variety of Great Northern history topics, including a biography of artist Winold Reiss and the story of the Great Northern's radio advertising program, Empire Builders. Tanner and his wife live in a quiet area of northwestern Montana.
