Fonds consists of records the Wilhelm E. Nassau created during his time at Wilfrid Laurier University, working in the development of the Audio-Visual department as a professor and curator of an extensive collection of photographic and film cameras and technology. This collection was amassed for the purpose of teaching students of the university and was curated by Nassau over the span of fourty years. Cameras were collected from students, faculty, and employees as well as purchased from local camera shows. The collection traced the history and development of the tools used in these fields. The collection was donated to both Brock University (motion picture and video materials) and the Ryerson University Library and Archives (still photography materials). Objects in the donation were distributed amoung the Heritage Camera Collection (2005.006), the Photography and Film Technology Collection (2005.005), and the Photographic Publications Collection (2005.003).
