Author Martha Rose Woodward is a retired school teacher who developed her interests in journalism as well as television and radio production after she left the field of education. Intrigued by the Sunsphere, a unique tower which was built as a theme structure for the 1982 Worlds Fair, Woodward began looking into the subject, turning her research into the book Knoxvilles Sunsphere: Biography of a Landmark (2007). Images of America: Knoxvilles 1982 Worlds Fair builds on this research and includes more than 200 vintage images.
