The Forbush family series includes a Forbush family daybook. Photographs found in this series relate to Elmer Forbush's family, including the Wallis and Hawley families. The personal correspondence of both Grace, Elmer, and Elizabeth Forbush can also be found in this series as well as Jonathan Forbush's (Elmer's father) marriage certificate. The papers of Scott Forbush comprise the bulk of this series. Biographical information on Scott includes a handwritten biography by Scott, various awards, and obituary written by his wife Julie, and an audiocassette of Scott's memorial service. Most of Scott's correspondence is personal, primarily written to and from his mother Grace and his grandfather Elisha M. Ellsworth. However, many letters discuss various topics relating to his work and his different jobs, especially while he was working in Peru. Some of Scott's writings and articles on his work are included, such as an article describing Scott's thoughts on receiving the Waring Prize, a summary of his lecture on his discovery of cosmic rays, and several essays and a pamphlet written by Scott for the El Instituto Carnegie de Washington. Photographs of Scott throughout his life are also included in this series.
