EXPANSION PASS — Additional Depth

Lesser-Known Actors

• Margarete von Brentano — Planck’s granddaughter and a philosophy professor who later became a key critic of the "Planck Myth," challenging the narrative of his seamless moral rectitude during the Third Reich.

Johannes Stark — Nobel laureate and leader of the Deutsche Physik* movement; Planck’s primary antagonist who lobbied the SS to label Planck a "White Jew" for his continued support of Einstein’s relativity.

• Karl-Friedrich Bonhoeffer — A physical chemist and friend of the Planck family; he provided a direct link between the scientific elite and the anti-Nazi resistance (brother of Dietrich Bonhoeffer).
• Ernst Telschow — General Secretary of the Kaiser Wilhelm Society (KWS) under Planck; a bureaucratic survivor who managed the transition of KWS into the Max Planck Society (MPG) by purging compromising files.
• Lise Meitner — Though famous, her role as Planck’s "protégée" is often sanitized; her private correspondence reveals her profound disappointment in Planck’s public silence during her forced exile in 1938.
• Bernhard Rust — Reich Minister of Science, Education, and Culture; the official with whom Planck had to negotiate the "cleansing" of the KWS and who famously mocked Planck’s pleas for Jewish colleagues.
• Anton Saefkow — A resistance leader whose underground cell Planck’s son, Erwin, was accused of supporting, leading to Erwin’s execution and Max’s ultimate psychological breaking point.
• Helmuth James Graf von Moltke — Founder of the Kreisau Circle; he consulted with Planck’s inner circle regarding the post-war reconstruction of German science before his own execution.

Document Deep-Cuts

• R 4901/25656 (Bundesarchiv Berlin) — Personal files of the Reichserziehungsministerium containing the 1933–1935 correspondence between Planck and Bernhard Rust regarding the dismissal of "non-Aryan" staff.
• Abt. I, Rep. 1A, Nr. 1656 (MPG Archives) — The "Harnack House" guest logs; these reveal the covert meetings held by Planck and his peers as they attempted to navigate the Nuremberg Laws.
• SS-Ahnenerbe Case File "Planck" (Microfilm T-175, National Archives) — Documentation of the SS investigation into Planck’s "ideological reliability" and his secret defense of the "Jewish" Theory of Relativity.
• The "Haber-Gedächtnisfeier" Dossier (1935) — Records of the banned memorial service for Fritz Haber organized by Planck in defiance of the Ministry, which nearly led to his forced resignation.
• ZStA, Rep. 92, Nr. 12 (Planck-Nachlass) — Planck’s private notebooks from 1944–1945, detailing his thoughts while hiding in the woods of Elbe to escape Allied bombing and Soviet advances.
• The 1946 "Göttingen Declaration" Drafts — Early versions of the document that repurposed the Kaiser Wilhelm Society into the Max Planck Society, showing the deliberate scrubbing of Nazi-era institutional names.

Wider Timeline

• 1889-04-23 — Planck is appointed to the chair of theoretical physics at Berlin University, succeeding Gustav Kirchhoff, establishing his base for the next 50 years.
• 1914-10-04 — Planck signs the "Manifesto of the Ninety-Three," a document defending German militarism at the start of WWI, an act he would later partially regret and attempt to walk back in 1916.
• 1929-02-22 — Planck delivers his "Concept of Causality" lecture, beginning his public pivot toward integrating religious belief with scientific determinism.
• 1933-05-16 — Planck meets personally with Adolf Hitler; he attempts to argue that the expulsion of Jewish scientists will harm German interests, to which Hitler famously rages that if science cannot do without Jews, Germany will do without science.
• 1938-12-22 — Otto Hahn and Fritz Strassmann discover nuclear fission at Planck's KWS institute; Planck is briefed but remains distanced from the subsequent "Uranium Club" weapons project.
• 1944-07-23 — Arrest of Erwin Planck following the failed Stauffenberg plot (July 20); Max begins a desperate, failed letter-writing campaign to Himmler and Hitler to save his son.
• 1945-01-23 — Erwin Planck is executed at Plötzensee Prison; Max receives the news weeks later, leading to his total withdrawal from public life.
• 1946-09-11 — Planck travels to London for the Royal Society’s Newton Tercentenary; he is the only German invited, serving as the "bridge" for the rehabilitation of German science.
• 1948-02-26 — Formal founding of the Max Planck Society in the British/US zones, explicitly using Planck’s name to shield the institution from de-Nazification scrutiny applied to the KWS.
• 2001-06-01 — The Max Planck Society issues its first comprehensive formal apology for the Kaiser Wilhelm Society’s involvement in Nazi crimes, including human experimentation.

Money & Operational Mechanics — Deeper

• The "Harnack House" Funding — Planck managed the KWS’s social hub, which was funded by a 2-million-mark grant from the Rockefeller Foundation (1929). During the Nazi era, this international funding was leveraged by Planck to argue against state interference.
• IG Farben Interlock — Operational mechanics of the KWS under Planck relied heavily on "Senators" from IG Farben (e.g., Carl Bosch). These industrial ties provided a financial buffer that allowed Planck to keep some "mischlinge" (half-Jewish) scientists on the payroll long after they were banned from civil service.
• The "Emergency Fund for German Science" (Notgemeinschaft) — Planck’s manipulation of these funds allowed him to provide "research grants" to displaced scholars, effectively creating a secret unemployment insurance for purged Jewish physicists before they could emigrate.
• The "Planck Constant" Patenting Myth — Unlike modern science, Planck’s era relied on "Stiftung" (Foundations). Planck’s operational power came from his ability to shift funds between the KWS and the Prussian Academy of Sciences, bypassing the Ministry of Finance.

Suppressed or Retracted Material

• The 1933 "Missing" Resignation — Planck drafted a resignation letter in protest of the Civil Service Law but was talked out of it by colleagues who argued he was the "last shield." The document was suppressed to prevent it from falling into Gestapo hands and only surfaced in private papers decades later.
• The Einstein-Planck Correspondence (Post-1933) — Einstein’s letters to Planck grew increasingly cold; these were largely suppressed in institutional MPG histories until the 1980s to maintain the image of the "unbroken" scientific community.
• War Research at KWS Institutes — While Planck was President, the KWS conducted research on "total war" materials. Post-1945 narratives retracted Planck's awareness of these programs, framing him as a "pure" theoretician unaware of the KWS’s logistical role in the war machine.
• Erwin Planck’s Confession — Records of Erwin’s interrogation under the Gestapo were largely kept from Max; they detailed a level of radicalism that Max, a staunch monarchist and legalist, likely could not have reconciled with his own worldview.

Open Threads — Specific FOIA / Investigative Targets

• Target: CIA / OSS Records (1944-1946) — Request files on "Operation Overcast/Paperclip" vetting of Max Planck. Reason: To determine if Allied intelligence considered Planck a collaborator or a high-value asset for post-war stabilization.
• Target: British Foreign Office (FO 1049) — Records concerning the 1946 reorganization of the Kaiser Wilhelm Society in the British Zone. Reason: To find internal memos regarding the decision to use "Max Planck" as a brand for de-Nazification.
• Target: Rockefeller Archive Center (RAC) — Correspondence between the Foundation and Planck (1933–1939). Reason: To track the flow of US dollars into German science during the transition to the Third Reich.

Target: Bundesarchiv (BArch R 9349) — Records of the Deutsche Chemische Gesellschaft*. Reason: To cross-reference Planck’s signatures on expulsion orders for Jewish chemists, which are often missing from the Physics archives.

• Target: Vatican Apostolic Archives (Pontificate of Pius XII) — Correspondence between Planck and the Pontifical Academy of Sciences. Reason: Planck was a member; research his attempts to use the Vatican as an intermediary for peace feelers in 1943.
