Series IV. Correspondence and related material
Most of Terhune's correspondence is with Robert L. McNeil,Jr., president of Barra Foundation Inc., which financed the publishing of Terhune's book. Their correspondence covers a 13-year period, beginning in 1984 when Terhune contacted the Foundation upon the recommendation of her graduate adviser William Gerdts. As chronicled in their letters, Terhune submitted her first manuscript in 1988, and through the 1990s was working on her rewrites while teaching art history courses. Another long-term correspondent was Nancy Corson, grandniece of Helen Corson Hovenden. Other correspondence documents Terhune's contact with several scholars, private collectors and research repositories, and issues of access to her dissertation while she worked on the book.
