Dorothy Bainton

Dorothy Bainton died of intestinal cancer on November 5, 2026, at her home in San Francisco, under the care of her family and hospice. She was 93.

Her family's obituary was published by the San Francisco Chronicle from November 10 to 15, 2026. No public memorial service had been announced at the time of writing. The family suggested gifts in her memory to the San Francisco Friends School Scholarship Fund, the UCSF Scholarship Fund, or a charity of the giver's choice.

Dorothy Dee Ford was born on June 18, 1933, in Magnolia, Mississippi, a town of about 1,800 people that serves as the county seat of Pike County, roughly 90 miles north of New Orleans. She was the first of three children of Aubrey Ratcliff Ford and Leta Brumfield Ford; her siblings were Aubrey Jerome Ford and Leta Frances Ford.

The Ford home stood at the corner of Clark and Bay streets, by the town's one streetlight, where the family ran a nursery and a gas station. Born in the middle of the Depression, Dee worked from childhood, rooting seedlings, grafting camellias, selling plants and helping manage the workers. Her family prized education and expected every child to go to college despite the sacrifice.

A gifted high school science teacher (in tenth grade, according to her family; the ASIP citation mentions an eighth grade biology class) sparked her interest in science, and she decided to become a doctor and return home to practise pediatrics. As the eldest child she also expected to become the safety net for aging relatives, and saw medicine as the way to do it. Her family remembered a quiet girl who listened and analyzed rather than gossiped, and who could spot four-leaf clovers in a patch of grass from 10 feet away.

She attended Millsaps College in Jackson, Mississippi, which Wikipedia records as awarding her a bachelor's degree in 1955. To save money she applied after three years for early admission to Tulane University School of Medicine in New Orleans. She was one of only a handful of women in a class of 128 (five according to her family's obituary, four according to the American Society for Investigative Pathology) and earned her MD in 1958.

She interned at Strong Memorial Hospital of the University of Rochester in New York, then in 1960 took a hematology fellowship with Dr. Clement Finch at the University of Washington in Seattle. After moving to San Francisco she studied electron microscopy at the University of California, Berkeley, so she could apply it to problems in blood disease.

In 1963 Bainton joined the laboratory of Marilyn Farquhar in the UCSF Department of Pathology as a postdoctoral fellow. Department chair Henry Moon allowed her a flexible schedule so she could care for her young children while doing research, an unusual arrangement at the time.

Using the electron microscope, Bainton and Farquhar traced how the granules of neutrophil white blood cells form. Their 1966 paper in the Journal of Cell Biology showed that two distinct types of granules, azurophil and specific granules, are derived from opposite faces of the Golgi complex in developing granulocytes, and a 1971 paper in the Journal of Experimental Medicine described the same process in human bone marrow. These became classic papers in hematology and cell biology.

Her laboratory went on to study changes in organelles as blood cells mature in bone marrow, the packaging and fate of their secretory products, macrophage maturation, platelets and megakaryocytes, abnormalities in leukemia, and how white cells defend the body in inflammation and infection. Her work was funded by the National Institutes of Health for about 30 years, with one grant reaching 30 uninterrupted years. By 1999 she had written 113 articles and 27 book chapters, and the ASIP observed that much of what textbooks describe about the development of leukocytes and megakaryocytes was first described by her.

She joined the pathology faculty in 1969 and was promoted to full professor in 1981.

In 1987 Bainton was appointed chair of the UCSF Department of Pathology, becoming the first woman to chair a department in the School of Medicine since its founding as Toland Medical College in 1864. She led the department until 1994. From 1993 to 1994 she also chaired the UCSF Academic Senate.

In 1994 she was appointed Vice Chancellor for Academic Affairs, a post she held until retiring in 2004. As vice chancellor she became a strong advocate for mentoring and promoting women who wanted careers in academic medicine. She pushed for family friendly policies, strengthened the campus sexual harassment guidelines and improved the merit and promotion system for women faculty. She also served as a distinguished expert with the California Council on Science and Technology.

While interning in Rochester she met Cedric Bainton, a fellow intern from Connecticut. Despite some family hesitation about her marrying a Yankee, the couple married in Magnolia on November 28, 1959, in a wedding organized by her childhood best friend and maid of honor, Ann Wiltshire. Cedric later trained in anesthesia at UCSF.

They had three sons, Roland, Bruce and James, all of whom became physicians. Their partners, Margo Vener Bainton, Lori Gardner Bainton and Jeff Rueda, are also physicians. Her grandchildren are Andy, Amy, Cevi, Samara and Adlai; a granddaughter, Rebecca, died of osteogenic sarcoma at the age of 15.

From her first summer in San Francisco in 1962, listening to Lon Simmons call the Giants on KSFO and sitting in the one dollar bleachers at Candlestick Park, she was a devoted Giants fan. Her family called her a "gamer babe" who listened to every game and attended as many as she could, often with her neighbor Phyllis Eggert, with whom she shared adjacent season tickets.

Bainton believed women should not have to choose between a family and a top academic career. A fellow faculty member, quoted in her family's obituary, said the model of a high achieving woman in medicine in the 1960s was single or childless, and that Bainton broke that mold by showing it could be done without settling for second tier positions. As vice chancellor she said the aim was to make sure women and men were not afraid to take time off to care for their families. Her family summed up her values as a love of life, family, medicine and the chance to uplift women.

Bainton's descriptions of how neutrophil granules and other blood cell organelles form remain part of the foundation of hematology and pathology teaching. Russell Ross of the University of Washington called her early papers on leukocytes, platelets, granule formation, leukemia and macrophage maturation "classics in the literature that have long stood the test of time."

At UCSF she opened the path to department leadership for women and used her years as vice chancellor to change policies on family leave, harassment and promotion. A colleague said that all the current young women leaders at UCSF were mentored by her, and that she not only mentored but nurtured and changed processes to make UCSF a kinder and better place.

Elected to the Institute of Medicine (now the National Academy of Medicine), 1990. Elected to the American Academy of Arts and Sciences, 1996, where she later served as chair-elect of the Section of Medical Sciences. Fellow of the American Association for the Advancement of Science. National Institutes of Health MERIT Award. Gold-Headed Cane Award, American Society for Investigative Pathology, 1999, the society's highest honor. UCSF Chancellor's Award for the Advancement of Women, 2003. UCSF Medal, 2009. Member of the American Society for Cell Biology, and president of the American Society of Pathology according to her family's obituary.
