The dismissal of Jewish scholars by Nazi Germany turned persecution into an immediate crisis for the international scientific community: Jewish professors were being driven from their posts, and physicists faced exile as well as the loss of their work. For J. Robert Oppenheimer, then largely detached from overt politics, the expulsions made political events impossible to treat as separate from the life of science. His response was both personal and material: he pledged part of his salary to support physicists trying to escape Germany.

Dismissals and the Flight of Physicists

After Adolf Hitler came to power in January 1933, German Jewish professors were summarily dismissed from their jobs by April. The removals extended beyond the immediate loss of university positions: scientists who would not accept the regime’s treatment of Jewish colleagues were forced to leave the country, scattering established intellectual communities across Europe and the United States.

James Franck’s experience made the coercion especially plain. A former professor of Oppenheimer’s at Göttingen and a veteran awarded two Iron Crosses during the First World War, Franck was initially among the few Jewish physicists permitted to keep his post. A year later, he was forced into exile after refusing to dismiss other Jewish staff. By 1935, he was teaching physics at Johns Hopkins University in Baltimore. Max Born, also driven from Göttingen in 1933, found a teaching post in England. These departures show how persecution reached beyond individual scholars: it displaced scientific work and carried the consequences of Germany’s policy into institutions abroad.

Oppenheimer’s Response

Before these events, Oppenheimer’s Berkeley circle could describe itself as not overtly political, and he had questioned what politics had to do with truth, goodness, and beauty. The dismissals mark the point at which that separation began to break down. In the spring of 1934, he received a circular soliciting money to support German physicists attempting to emigrate and immediately agreed to earmark three percent of his salary—about one hundred dollars a year—for two years.

The account does not establish which refugees received that money. It identifies Franck as someone who may have benefited, not as a confirmed recipient. That uncertainty matters: Oppenheimer’s documented act was the commitment itself, a decision to direct a portion of his academic income toward scientists driven from their country.

From Private Concern to Political Engagement

The expulsions formed part of a wider sequence of events that drew Oppenheimer into public and political questions. The news from Germany was grim, while labor conflict and political polarization were also becoming harder to ignore in Berkeley and California. The book presents these pressures together rather than as a single-cause conversion: the dismissal of Jewish scholars was an early, concrete intrusion of politics into Oppenheimer’s scientific world, not the sole explanation for his later activity.

By the late 1930s, he was giving speeches on political issues and signing petitions. After the 1939 Nazi-Soviet pact, he discussed the pact with fellow intellectuals; in 1940, pamphlets associated with the Communist Party of California defended the New Deal and criticized the political course of the war, though the extent of Oppenheimer’s authorship remains uncertain. The progression is significant without making his later positions inevitable: a crisis that began with colleagues and professors being forced from their posts helped make political responsibility harder for him to regard as an abstraction.

Significance

The episode connects persecution abroad with the choices available to scientists elsewhere. German universities lost scholars, while universities in England and the United States became destinations for exiles; Oppenheimer, still a professor at Berkeley, responded by committing money to aid emigration. The event also supplies an early context for his growing attention to the political conditions surrounding scientific work. Its importance lies not in a claim that one act of persecution determined his later views, but in the way it made the vulnerability of scientists—and the consequences of political power for scientific communities—visible within his own life.
