Guttulinopsis vulgaris and nivea

Photographs: There are 22 boxes of photographs containing prints arranged by size: 16 x 18 (Box #23); 11 x 14 (Box #24); 8.5 x 11 (Boxes #25-27); 5 x 7 (#28-30); 3 x 5 (#31-44). Most relate to the growth and life cycles of Aspergillus, Penicillium, Dictyosteliaceae and related organisms. This record documents microscopic structures such as spores, macrocysts, amoebae, and sorocarps of cellular slime molds (and similar structures of the microfungi) in various isolations and experiments using optical and electron microscopy. There are photos of fungal cultures in petri dishes, as well as glossy and matte photos of charts, diagrams, graphs, and text. Photos are arranged alphabetically by genus (and/or subject) where applicable.

One sequence of folders contains prints used for figures in published articles by Dr. Raper and his collaborators. There is also a complete series of mounted photos of figures used in The Dictyostelids (see Series 2). The research of the Northern Regional Research Laboratory is documented with photos of building and grounds, fermentation and laboratory equipment, microbiological subjects, and group and individual portraits, including the NRRL "Penicillin Team." Other portraits pertain to events of IBC XI, University of Wisconsin faculty and staff, and Charles Thom and associates.

Negatives: There are 21 boxes of photographic negatives arranged by size: 8.5 x 11 (Box #27); 5 x 7 (Box #54); 3 x 5 (Boxes #45-53; 55). There are 8 boxes of glass negatives (#56-63) and one of Kodachrome slides (#64). In most cases negatives relate to corresponding positive prints. Negatives are arranged alphabetically by genus (and/or subject) following the sequential ordering of photographs in Series 17 wherever possible. There is one sequence of 206 negatives (Box #65) of specimen material. See Series 14.

Other Media: There are 31 boxes of lantern slides, most of which duplicates the photographic record described above. There are 31 spools of 16mm film of the germination and development of cellular slime molds in culture and 2 spools of 35mm film, subjects unidentified. There is one videocassette of filming done in Peoria, Illinois for a British Broadcasting Corporation (BBC TV) documentary on penicillin that includes footage of an interview with Dr. Raper. Finally, there are 58 plates (5 boxes) of Aspergillus, Dictyostelium, et al used as figures in published articles.
