Stanford University

Stanford University appears in this account less as an institutional actor than as a meeting ground for medical training, scientific work, and political commitment. Its School of Medicine shaped Jean Tatlock’s path to becoming a physician and psychiatrist and formed the professional base of Thomas Addis, whose friendship and advice helped direct J. Robert Oppenheimer’s contributions toward the Spanish Republican cause. The university’s significance here lies in those lives and connections, not in evidence that Stanford itself sponsored their politics.

Medical training and Jean Tatlock

The Stanford University School of Medicine was located in San Francisco when Tatlock attended it. After studying premedical subjects at the University of California, Berkeley, in 1933–34, she graduated from Vassar College in June 1935 and continued her medical education at Stanford. By the spring of 1936, when she met Oppenheimer at a party hosted by Mary Ellen Washburn, she was finishing her first year at the medical school. Her course of study thus preceded their relationship and was an independent professional undertaking, not simply an accompaniment to it.

Tatlock’s choice of medicine grew from interests that crossed disciplinary and political lines. An earlier stay in Switzerland had introduced her to the Jungian psychoanalytic community and helped awaken her interest in psychology. At Vassar she studied English literature; at Berkeley she also reported for the Western Worker and attended Communist Party meetings. Her concern about social injustice and her interest in psychological questions both informed her wish to help people directly. A friend later connected her social conscience and exposure to Jung with her decision to become a doctor. The combination did not resolve into a single intellectual doctrine: Tatlock aspired to psychoanalysis even though Communist Party orthodoxy treated Freudian thought and Marxism as incompatible.

She completed her medical degree at Stanford in June 1941. She then spent 1941–42 as an intern at St. Elizabeth’s psychiatric hospital in Washington, D.C., and the next year as a resident physician at Mount Zion Hospital in San Francisco. These appointments mark the continuation of a career she pursued after rejecting Oppenheimer’s renewed offer of marriage. Her medical education and work therefore have a trajectory of their own within the biography: Stanford was a formative institution in a professional life Tatlock maintained through political commitments and a complicated personal relationship.

Thomas Addis and Stanford’s medical work

Addis was a distinguished Stanford physician-scientist and a mentor to Tatlock during her medical studies. In 1911 he became chief of the Clinical Laboratory at Stanford University School of Medicine in San Francisco, beginning a long career there. He pioneered the treatment of kidney disease, wrote two books on nephritis and more than 130 scientific papers, and became a leading American authority on the disease. His work combined medical research with clinical practice; colleagues described him as both scientist and clinician. In 1944 he was elected to the National Academy of Sciences.

His professional standing coexisted with political commitments that extended well beyond the university. Addis advocated civil rights for Black people, Jews, and union members, supported civic organizations, and opposed fascism. After attending the International Physiological Congress in Leningrad in 1935, he returned impressed by Soviet public-health programs and later campaigned for national health insurance. The American Medical Association eventually expelled him over that advocacy. Stanford colleagues could regard his admiration for the Soviet system as a personal conviction while continuing to respect his scientific work; the account does not present his politics as Stanford policy.

By the late 1930s, the FBI described Addis as an important recruiter of white-collar professionals for the Communist Party, and Oppenheimer later believed him either a Communist or close to one. Those descriptions belong to the political scrutiny surrounding Addis, not to an institutional position taken by Stanford. His medical career, civic activism, and personal associations overlapped in one person, making him a consequential intermediary between Oppenheimer’s professional circle and left-wing relief efforts.

A university connection becomes a political channel

In the winter of 1937–38, Tatlock introduced Oppenheimer to Addis. She knew him as a friend and mentor from her medical studies; Addis became a friend of Oppenheimer as well. Their shared acquaintances included Haakon Chevalier and Linus Pauling. Addis’s breadth of interest impressed Oppenheimer, who saw in him an intellectual whose engagement with science, poetry, music, and economics belonged together rather than occupying separate compartments.

The connection acquired practical consequences through aid for the Spanish Republic. Tatlock and Oppenheimer organized fund-raisers for Spanish relief groups, and Addis first approached Oppenheimer for contributions in his capacity with the United American Spanish Aid Committee. He later met Oppenheimer privately in his Stanford laboratory and advised him to route money through Communist channels if he wanted it to support the fighting effort. Oppenheimer subsequently gave cash payments to Addis, usually at the laboratory or Addis’s home; after Addis suggested a more convenient arrangement, Oppenheimer gave money to Isaac Folkoff, a veteran member of the San Francisco Communist Party.

Oppenheimer chose cash because he thought contributions for military equipment, unlike medical relief, might not be entirely legal. He understood from Addis that the money would reach the fighting effort. The laboratory and home were thus settings for private transactions made possible by a personal relationship; the evidence does not indicate that Stanford University authorized or administered them. The distinction matters: Stanford supplied Addis’s professional setting and connected him to Tatlock’s medical education, while the political decision and its risks belonged to the individuals involved.

Significance in the biography

The Stanford connection helps show how Oppenheimer’s political associations developed through overlapping professional, personal, and humanitarian networks. Tatlock’s medical education brought her into Addis’s orbit; her introduction brought Addis into Oppenheimer’s; and their work for Spanish relief turned acquaintance into a channel for financial support. The sequence does not make the university the cause of Oppenheimer’s politics. Rather, Stanford’s medical community is one setting in which people with distinct careers and convictions encountered one another.

That distinction also preserves Tatlock’s agency. She was not merely the route by which Oppenheimer met Addis: she pursued medical training, sought a career in psychiatry, and had her own political record and reasons for supporting practical relief. Addis, likewise, was not only a donor solicitor or political contact; he was a prominent kidney-disease researcher whose Stanford career stood alongside his civic activism. The institution’s place in the narrative is therefore best understood through these parallel lives, whose professional work and public commitments met without becoming identical.
