David G. Chase Collection, ca.1975-1987.
3 boxes (4.5 linear feet).
Call no.: MS 809
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.

Charles F. Clagg Photograph Collection, 1930 June-July.
1 folder (0.1 linear feet).
Call no.: PH 016
The entomologist Charles F. Clagg was born in Barnstable, Mass., in 1904 and received his bachelor of science degree from the Massachusetts Agricultural College in 1927. Although never able to complete his graduate degree, Clagg enjoyed a long and productive career in entomology. Listed as a graduate student at MAC in 1929-1930, Clagg took part in an extensive collecting trip to the Philippines in 1930 and 1931. Beginning in June 1930 near Calian in Davao del Sur (Mindanao), Clagg spent several months collecting flies in and around the active Mount Apo volcano, in the Lawa and Calian river valleys, and in the Lalun mountains, traveling to the eastern peninsula of Davao early in 1931. He remained in the Pacific region later in his career, working as an entomologist for the U.S. Navy.
The twenty photographs taken by Charles F. Clagg in 1930 document his entomological collecting trip to Davao, Mindanao, in the Philippines. Primarily personal in nature, rather than professional, they were taken on Clagg’s visit to a coconut plantation run by American expatriates Henry and George Pahl and illustrate the local sights in Davao, including work in harvesting coconuts and the production of copra, the production of Manilla hemp, a horse fight at Calian, and Manobos who came to the plantation trade. Also included are three photographs of Clagg’s quarters while collecting high in the Lalun Mountains. The captions provided by Clagg on the back of each photograph have been transcribed verbatim.

Alvin P. Cohen Collection, 1957-1968.
2 boxes (1.6 linear feet).
Call no.: FS 145
As an undergraduate at the University of California Berkeley in the late 1950s, Alvin P. Cohen planned on a career in engineering, but after earning his bachelors degree and working as a laboratory technician, he returned to undergraduate status and then to graduate school in Chinese. Cohen’s time at Berkeley coincided with the turbulence of the first wave of student revolt, the civil rights and antiwar movements, and the Free Speech Movement, however as a married man with children, he was more an observer than activist. After completing his dissertation, The Avenging Ghost: Moral Judgment in Chinese Historical Texts, in 1971, he joined the faculty at UMass Amherst, initially with a split appointment teaching Chinese and working as East Asian bibliographer in the library. Over the next three and a half decades, he helped build the Program in Asian Languages and Literature, becoming its Chair in the 1990s and President of the Warring States Project.
Consisting of newsclippings, fliers, and other ephemera collected as the Free Speech Movement was at its height, the Cohen collection provides a valuable window on 1960s activism and the cross-fertilization between the various student movements. The materials cover a range of issues from free speech on campus to the California legislature, civil rights, the war in Vietnam, and the House Un-American Activities Committee. Of particular interest is a letter received by Cohen from a friend Doug Wachter in 1960, shortly after Wachter had been called before HUAC.
