Chase, David G.

An electron microscopist affiliated with the Sepulveda Veterans Administration Hospital, David Chase (1935-1986) was known for his skill in fixation, staining, and sectioning and for the exceptional quality of his micrographs. During his career, Chase applied his skills to produce thousands of images of the structure, ultrastructure, and morphology of prokaryotes, ranging from filamented, segmented bacteria to the flagellate Giardia, and gram-negative bacteria. In collaboration with Lynn Margulis of the UMass Amherst Department of Biology, Chase worked on a series of papers on the symbiotic flagellated protozoan communities in the hindguts of four species of California termites.

The Chase collection consists of over 1,800 TEM photos and their negatives, 134 polaroid prints, and about half a linear foot of loose notes and a register.
