Siegfried Bernfeld

Siegfried Bernfeld was a Viennese psychoanalyst and teacher whose flight from Nazi Europe brought him to California, where he gathered intellectuals to examine the workings of the mind. His importance in J. Robert Oppenheimer’s life lay not only in the seminars and study group he led, but in the unusual convergence he represented: a refugee and political idealist attempting to bring psychoanalysis into conversation with Marxism, and an analyst whose subject matter drew the attention of a physicist still marked by an earlier psychological crisis.

Refugee, analyst, and political idealist

In 1937, Bernfeld fled Europe as Nazism spread. He first went to London, where the psychoanalyst Ernest Jones advised him to go west rather than settle there. By September, Bernfeld had established himself in San Francisco, a city with only one practicing analyst at the time. His wife, Suzanne, was also a psychoanalyst. The couple’s arrival followed a stark change in circumstances: Suzanne’s father had been a prominent Berlin art-gallery impresario who helped introduce Cézanne and Picasso to the German public, but the Bernfelds had to sell one of the last paintings remaining from their once-impressive collection to meet their living expenses.

Bernfeld brought more than professional expertise to his new surroundings. In Austria, he had first become politically active as a Zionist and later as a socialist. He was an eloquent teacher and passionate idealist, and he belonged to a small group of Freudian analysts trying to integrate psychoanalysis with Marxism. His intellectual commitments thus joined questions about individual psychology to wider political concerns, without reducing one to the other.

A distinctive personal detail made his arrival visible to Oppenheimer: Bernfeld was tall and gaunt, and wore a porkpie hat, a felt hat with a low, flat top. Oppenheimer was impressed enough to adopt a similar hat. The gesture registers the force of Bernfeld’s presence in a small, concrete way: his influence was not confined to the ideas discussed in a seminar room.

The San Francisco study group

Within weeks of settling in San Francisco, Bernfeld organized a regular discussion group that brought together leading intellectuals from several fields. Alongside Oppenheimer were Edward Tolman, Ernest Hilgard, Donald and Jean Macfarlane, Erik Erikson, Ernst Wolff, Stephen Pepper, and Robert Lowie. Their different professions made the group interdisciplinary in practice, not merely in name: its members included psychologists and psychoanalysts, a pediatrician, a philosophy professor, an anthropologist, and a physicist.

They met in private homes, drank wine, smoked cigarettes, and discussed psychoanalytic subjects including fear of castration and the psychology of war. Bernfeld sometimes spoke about individual cases from his therapy work. Like his mentor Freud, he lectured without notes, smoking one cigarette after another. Nathan Adler, another psychoanalyst, remembered both the eloquence of Bernfeld’s speech and the aesthetic force of listening to it. The account presents Bernfeld not simply as the group’s organizer but as its compelling speaker: the manner of his exposition was part of its appeal.

Oppenheimer, the only physicist in the group, was remembered as intensely interested in psychoanalysis. From 1938 through 1941, he found time to attend Bernfeld’s seminars. The discussion group eventually contributed to a more lasting institution: in 1942, it gave rise to the San Francisco Psychoanalytic Institute and Society. Bernfeld’s local work therefore extended beyond a circle of private conversations, even though the evidence describes the institute’s formation as an outcome of the group rather than as Bernfeld’s solitary achievement.

Oppenheimer and the psychological

Bernfeld’s teaching met a particular interest in Oppenheimer. Oppenheimer had painful memories of his youthful encounters with psychiatrists, but his difficult earlier experience did not make him indifferent to psychological inquiry. The book connects his attention to Erikson’s discussion of identity formation in young adults: Erikson proposed that prolonged adolescence and chronic disturbance could reflect trouble shedding unwanted fragments of personality, and that the search for wholeness could coexist with fear of losing one’s identity. In some cases, he argued, this conflict could issue in rage and arbitrary destructive acts.

The account notes that Oppenheimer’s behavior and problems in 1925–26 conformed in significant ways to that thesis, while also distinguishing the later intellectual framework from the earlier events. Oppenheimer had thrown himself into theoretical physics and built a robust identity, but psychological scars remained. This comparison gives the Bernfeld circle a meaning beyond its program of study: its discussions offered Oppenheimer a vocabulary for concerns that his scientific career had not simply erased. The evidence does not make Bernfeld the author of a diagnosis of Oppenheimer; it places Oppenheimer’s interest in psychoanalysis beside the crisis and lingering vulnerability of his past.

Oppenheimer’s psychological curiosity also belonged to a wider pattern in his intellectual life. Wolfgang Pauli once complained to Isidor Isaac Rabi that Oppenheimer seemed to treat physics as an avocation and psychoanalysis as a vocation. The remark captures the apparent imbalance that others perceived, while the account itself presents the two interests as complementary. For Oppenheimer, Bernfeld’s seminars offered a sustained encounter with questions of personality and the unconscious alongside his work in physics.

A shared intellectual and personal context

Bernfeld’s connection to Oppenheimer also intersected with Oppenheimer’s relationship with Jean Tatlock. Tatlock was training to become a psychiatrist, shared Oppenheimer’s introspective interest in the unconscious, knew some members of Bernfeld’s circle, and was later analyzed by Bernfeld as part of her training. She was not a member of the monthly group, so her connection to it was adjacent rather than formal. The account nevertheless places the group within a broader social and intellectual world in which Oppenheimer and Tatlock’s interests overlapped.

Bernfeld’s political commitments offered another point of connection. Oppenheimer, then a political activist, chose to study psychoanalysis under the guidance of a Marxist Freudian analyst. The fit was intellectual as well as personal: Bernfeld’s effort to relate individual psychology to Marxism belonged to a current of thought that could speak to Oppenheimer’s simultaneous engagement with psychological questions and political causes. Taken together, Bernfeld’s refugee history, his San Francisco circle, and his teaching show how an émigré intellectual helped establish a setting in which disciplines and political concerns could meet—and in which Oppenheimer’s fascination with the psyche found sustained company.
