Papers of Benjamin W. Zweifach, pioneering researcher in the field of microcirculation and co-founder of the Bioengineering Department at the University of California, San Diego. Zweifach served as professor of bioengineering at UCSD from 1966-1981 and was designated emeritus professor of bioengineering in 1981. His areas of specialization included cardiovascular physiology, the lymphatic system, the inflammatory process, blood-tissue exchange, shock, blood rheology, and the contribution of endothelial cells and the blood leukocytes to the microcirculatory imbalance in hypertension and diabetes. The papers include correspondence, writings and original research by Zweifach, writings by others annotated by Zweifach, and photographs, slides and films related to Zweifach's life and research. The papers are arranged in eleven series: 1) BIOGRAPHICAL MATERIALS, 2) CORRESPONDENCE, 3) WRITINGS AND RESEARCH, 4) WRITINGS BY OTHERS, 5) TEACHING MATERIALS, 6) SUBJECT FILES, 7) CONFERENCES AND MEETINGS, 8) PROFESSIONAL ORGANIZATIONS, 9) PHOTOGRAPHS, SLIDES, AND FILMS, 10) MISCELLANEOUS MATERIALS, and 11) ORIGINALS OF PRESERVATION PHOTOCOPIES.

Born in New York City to Eastern European immigrants in 1911, Benjamin W. Zweifach received a B.S. degree in biology in 1931 from the College of the City of New York and a Ph.D. in cellular physiology from New York University Medical College in 1936. His first publications were some of the earliest micromanipulative studies of the capillary blood vessels in living tissue. Beginning with these studies, Zweifach devoted his career to the study of the smallest blood vessels in the circulation system.
