Marilyn Gist Farquhar (July 11, 1928 – November 23, 2019) was a pathologist and cellular biologist, Professor of Cellular and Molecular Medicine and Pathology, as well as the chair of the Department of Cellular and Molecular Medicine at the University of California, San Diego School of Medicine, who previously worked at Yale University from 1973 to 1990. She has won the E. B. Wilson Medal and the FASEB Excellence in Science Award. She was married to Nobel Laureate George Emil Palade from 1970 to his death in 2008. Her research focuses on control of intracellular membrane traffic and the molecular pathogenesis of auto immune kidney diseases. She has yielded a number of discoveries in basic biomedical research including: mechanisms of kidney disease, organization of functions that attach cells to one another, and mechanisms of secretions.
Early life Marilyn Gist Farquhar was born on 11 July 1928 and was raised in the Central Valley farming community of Tulare, California. Her father was from a pioneer family and worked as an insurance agent and farmer, who spent his free time writing novels. Her mother was also from a pioneer family and had begun college, but had to return home before completing her degree. Farquhar attributes her desire to pursue a career in medicine and biology to her mother's friend, Frances Zumwalt, who was a pediatrician.
Education and career Farquhar received her undergraduate degree in zoology and experimental pathology from the University of California, Berkeley. After graduation, Farquhar was admitted to the medical school at the University of California, Berkeley. In 1951, Farquhar married another medical student, with whom she had two sons. However, after two years of medical school, Farquhar shifted to a Ph.D. program where she completed her degree in experimental pathology in 1955. During her time as a graduate student, she worked in the laboratory as a junior research pathologist and then an assistant research pathologist, after completing her Ph.D., under a pathology professor who was interested in glomerular disease. Farquhar later collaborated with the University of Minnesota as a research to study renal biopsies, where they were the first to see glomerular pathology at the electron microscope level. In 1958, she left the University of California, San Francisco to do post-doctoral work as a research associate in cell biology at Rockefeller University under George Palade. At the time, many pioneers in cell biology had worked or were currently working in this lab, where there were new discoveries almost every day due to the recent innovation of the electron microscope. George Palade was working on the kidney glomerulus at the time and provided Farquhar with formal training in the field of cell biology. Together Farquhar and Palade named tight junctions and adherens junctions. Since then, Farquhar has continued to study junctions in the podocytes. After leaving Rockefeller in 1962, she established her own laboratory at the University of California, San Francisco where she became a Professor of Pathology. Her lab focused on using tracers and cytochemistry to investigate the secretory process in pituitary cells and leukocytes. This work yielded the first description of crinophagy, the process by which secretory granules are taken up and disposed of in multivesicular bodies and lysosomes. In 1970, she divorced her first husband and married George Palade when she decided to take a sabbatical back at Rockefeller University. At the time, she was the only woman professor when she was then appointed Professor of Cell Biology. In 1973, Farquhar returned to the University of California at San Francisco, where she remained as a professor of cell biology and pathology for the next 15 years. In 1987, she jointed Palade at Yale where she became Sterling Professor of Cell Biology and Pathology. Here she built a new Department of Cell Biology in the medical school with George Palade and James D. Jamieson. While at Yale, Farquhar's research focused on secretory granule membranes that merge with cell membranes during exocytosis. She also identified several glomerular components that play a role in glomerular functions. In 1990, Farquhar and Palade returned home to California to help build and strengthen cell and molecular biology at the University of California, San Diego School of Medicine. Farquhar was a Professor of Cellular and Molecular Medicine and Pathology, as well as the chair of the Department of Cellular and Molecular Medicine at the University of California, San Diego School of Medicine. Her focus was on a molecule called GIV that regulates cell migration in response to growth factors and determines the fate of growth factor receptors. Throughout Farquhar's lifetime, she has witnessed and helped guide the evolution of the field of cellular biology.
