New oral history: Doris Sloan

Video clip from Doris Sloan’s oral history on living in the Bay Area, on deep time, and on thinking like a geologist:

Doris Sloan is a geologist and paleontologist who earned her PhD at UC Berkeley and who taught, wrote, and engaged in environmental activism and education throughout the Bay Area, across California, and beyond. Sloan and I recorded nine hours of her then 92-year life history at her home in Berkeley, California, in May 2022. Our four recording sessions resulted in a 162-page oral history volume that includes an appendix of photographs with family as well as documents from her efforts in the early 1960s to stop PG&E’s construction of a nuclear power plant atop Bodega Head, under which runs the seismic San Andreas fault. Today, the coastal outcrop of Bodega Head is preserved as part of California’s scenic 17-mile-long Sonoma Coast State Park.

Sloan’s involvement in the “Battle for Bodega Head” helped inspire her later career as a geologist and teacher—a career she began by returning to graduate school as a mother in her early forties with children still at home. Sloan overcame numerous challenges, including gender discrimination in what were then male dominated departments and academic fields, to earn her MS in Geology in 1975 and her PhD in Paleontology in 1981. Her dissertation was an ecostratigraphic thesis on the sedimentary fossils of tiny creatures that once lived the San Francisco Bay. For many years, Sloan taught research-driven senior seminars in Environmental Science at UC Berkeley as well as geology courses for UC Extension. She lectured on travel excursions and field trips around California and across much of the Earth. Sloan became a board member with Save the Bay and a founding member of Citizens for East Shore Parks. In 2006, she published with UC Press the popular California natural history guide, Geology of the San Francisco Region. In her rich oral history, Sloan discussed all of the above, with details on her formative childhood experiences, her environmental and anti-nuclear activism, her experiences as a female geology graduate student at UC Berkeley, as well as her diverse teaching career.

Doris Sloan was born in October 1930, in Freiburg, Germany. At age four, she and her family fled Germany after the Nazis removed her father, preeminent embryologist Viktor Hamburger, from the faculty at the University of Freiburg because of his Jewish ancestry. Her family settled in Missouri after her father secured a faculty appointment at Washington University in St. Louis. As a young girl, Sloan accompanied her father and his embryology students on field research trips to collect salamander eggs. She also shared fond memories of youthful summers working in Woods Hole on Cape Cod at the Marine Biological Laboratory. Sloan attended Bryn Mawr College from 1948 to 1951, where she began attending Quaker meetings. Upon her mother’s deteriorating health, Sloan returned to St. Louis and graduated in 1952 from Washington University with a BA in Sociology. In that same year Sloan moved to San Francisco, California, with her then-husband, with whom she had four children. In 1957, she and her young family moved to Sonoma County, where she was neighbors with Peanuts cartoonist Charles Schulz. It was there in Sonoma County where, in the interests of protecting her children from nuclear radiation and preserving the beauty of the Sonoma Coast, that Sloan began her environmental activism that would, among other experiences, inspire her later career as a geologist and teacher.

Sloan detailed her engagements in the multi-year “Battle of Bodega Head” that, in 1964, successfully stopped PG&E’s construction of a nuclear power plant on Bodega Head. After being told by an official from California’s Office of Atomic Energy Development and Radiation Protection to let go of concerns about the forthcoming nuclear plant and “leave it to the experts,” Sloan enlisted in the activist organization called the Northern California Association to Preserve Bodega Head and Harbor (NCAPBHH)—a name others created and she described as “dreamt up on a Friday night after too many beers.” The Association included an eclectic mix of anti-nuclear citizen activists that included communist chicken farmers, libertarian land owners, conservative cattle ranchers, Bodega fisherman, UC Berkeley professors, Sierra Club members, and jazz musicians and songwriters. In her role as Sonoma County Coordinator of NCAPBHH, Sloan also collaborated with an internationally recognized geophysicist and geologist named Pierre Saint-Amand. Fortuitously, on a rainy and wind-swept day, Sloan accompanied Saint-Amand on a clandestine and consequential visit to the “Hole in the Head,” the site on Bodega Head where PG&E had already drilled a deep pit into granite rock to place its nuclear reactor. It was on that visit, while looking into that hole, that Saint-Amand and Sloan discovered evidence of the San Andreas fault running directly through the reactor’s containment site, a discovery that eventually halted further nuclear construction there.

As Sloan recalled about their activist victory in the early 1960s, “to have a group of citizens win out over a major institution was really pretty unique. … Bodega was a very important story at the very beginning of a huge cultural shift for not only environmental matters on nuclear energy, but in so many other ways, too. Basically, citizen involvement at every level, from students to housewives. And to be a part of that, I look back on that and think, wow, how could anybody have been so lucky in so many ways?” The story of this citizen-led anti-nuclear activism has been told elsewhere, including in Oral History Center interviews with David Pesonen and Joel Hedgpeth, as well as by nuclear historians J. Samuel Walker and UC Berkeley alumnus Thomas Wellock. Sloan’s storytelling on her personal role in the “Battle of Bodega Head”—like launching over a thousand helium-filled balloons from Bodega Head to the accompaniment of live jazz playing “Blues Over Bodega”—adds both flourish and important details to the eventual successes of NCAPBHH.

Sloan’s involvement at Bodega Head played a crucial role in launching the next phase of her life as a geologist and teacher. After moving with her children to Berkeley in 1963, Sloan worked for the Friends Committee on Legislation, a Quaker lobbying group. Yet, by the early 1970s, Sloan’s long-standing fascination of nature, a desire to experience more of it, and her memory of discovering fault seams on Bodega Head led her to take UC Extension courses on geology taught high up in the Sierra Nevada’s Emigrant Wilderness by a remarkable UC Berkeley professor named Clyde Wahrhaftig. Wahrhaftig eventually became a significant mentor and friend to Sloan on her academic journey, as were UC Berkeley geologists Garniss Curtis and William B.N. (Bill) Berry. In her oral history, Sloan shares many joys from her field research and academic experiences at Berkeley, including mapping rock formations in California’s Mazourka Canyon, communing with ancient bristlecone pines in the White Mountains, learning about limestone deposition in Florida, a fascinating question about an imaginary dinosaur civilization from Walter Alvarez during her PhD oral examination, and her own work deciphering the sedimentary mysteries of fossils from mud under the San Francisco Bay. Sloan also shared some of the challenges she faced in the late 1970s as one of the few women in Berkeley’s geology and paleontology departments that, by her account, then included more than a few male chauvinistic dinosaurs.

Sloan’s oral history also explores her ensuing years as a teacher, travel guide, author, and environmental activist. Sloan discussed several senior research seminars in Environmental Studies that she taught at UC Berkeley, some records of which are preserved in UC Berkeley’s Library including East Bay Parklands: Planning and Management (1978), Seismic Safety in Berkeley (1979), San Pablo Bay: An Environmental Perspective (1980), and Hazardous Substances: A Community Perspective (1984). Sloan recorded stories and samples from lectures she delivered in her UC Extension geology courses and in her field classes for numerous organizations, including the Oakland Museum, Sierra Club, the Point Reyes National Seashore Association, and the Yosemite Association. And she shared some of her travel experiences as a guide for Cal Alumni groups on journeys all across the Earth, from the Himalayas to Central Asia, and from South America to Scandinavia. Sloan also spoke about her local environmental activism as a board member of Save The Bay, as a founding member of Citizens for East Shore Parks, and on her friendship with Save The Bay co-founder Sylvia McLaughlin, including efforts to secure what is now named as McLaughlin Eastshore State Park.

Doris Sloan’s enlightening oral history records marvelous stories from the first ninety-two years of her remarkable life—from fleeing Nazi Germany to summers in Woods Hole; from raising children in northern California to stopping construction of a nuclear power plant on the San Andreas fault; from graduate school in her forties at UC Berkeley to lecturing across California and much of the world. I am honored to have become one of Doris’s friends, and I’m lucky for the opportunity to become one of her students. Now, with the publication of Doris Sloan’s oral history, you also have the chance to learn from her deep wisdom and experience.
