The Historical series (1860-2004, 14 linear ft.) consists of data, audiovisual materials, artifacts, and other collected records documenting the many uses and functions of the Observatory throughout its history. The series includes records of observations and research activities conducted at the Detroit Observatory as well as some observational data from as early as 1800. Some of these records were apparently held by the university Department of Astronomy, individual faculty members and private collectors. When the Observatory was reopened for educational and public programming activities in the 1990s, director Sandy Whitesell began acquiring historical records of the observatory. The Historical series has been organized by material type into three subseries: Records and Observational Data, Audiovisual Materials, and Artifacts.
The Audiovisual Materials sub-series includes photographs, lantern slides, photo negatives, etchings, and microfilm. These materials document various astronomical subject matter, people, the Detroit Observatory, astronomical observations (including solar flares, planets, stars, and Halley's Comet) other observatories around the world, and scientific instruments.
Additionally, moving image and audio recordings contain historic footage of various observations as well as Observatory construction and restoration projects.
