The Open Option
How a Swiss holding company outlasted two governments, a World Court ruling, and twenty years of its own ambiguity
Randy Gipe · Claude / Anthropic · 2026
On a winter morning in 1965, a Wall Street syndicate led by Blyth & Company placed a sealed bid of nearly $330 million for a chemical and film company most Americans had never heard of. The bid wasn’t really for the company. It was the closing payment on a dispute that had outlived its own urgency — one that had gone to the World Court, nearly collapsed in the Kennedy White House, and would not be fully understood, even by the governments that fought over it, for another thirty years.
The company being sold was General Aniline & Film. The seller, at least on paper, was a Basel holding firm called Interhandel. The real question — the one nobody in 1965 could answer with certainty, and the one this piece tries to answer using the record now available — was simple to ask and almost impossible to settle: whose money was it?
I. The Source
I.G. Farben, formed in 1925 from the merger of six German chemical giants — BASF, Bayer, Hoechst, Agfa, Cassella, and Kalle — was by the late 1920s one of the largest industrial enterprises in the world, with foreign holdings stretching across Europe and the Americas. Its largest American subsidiary, General Aniline & Film, anchored a U.S. dye, film, and chemical business worth tens of millions of dollars. None of this was secret. It was simply ordinary multinational scale.

II. The Holding Company
In 1928 and 1929, Farben created a Swiss financial holding company in Basel — first known as I.G. Chemie — to hold its foreign investments, including its American interests, and to help raise capital abroad. This was not concealment. The relationship was openly acknowledged at the time; advertising the Farben connection was, if anything, good for business, since it signaled the backing of a major industrial concern to international investors.
What made the arrangement durable wasn’t secrecy. It was structure. An option-and-dividend-guarantee contract let Farben buy back I.G. Chemie’s holdings at book value whenever it chose, while guaranteeing Chemie’s shareholders a dividend matched to Farben’s own. Control ran not through the visible share register but through a smaller class of preferred shares carrying outsized voting power, held by a tight circle of trusted intermediaries — chief among them the Swiss banker Eduard Greutert, whose firm had helped Farben set up the structure in the first place. Personal trust did real work here: several of the relationships between the German and Swiss principals predated the First World War.
▸ Conversion
III. The Severance
By the late 1930s, Farben’s American holdings had become a liability rather than an asset. War was approaching, and any company with traceable German ownership stood to lose its U.S. property the moment hostilities began, under the Trading with the Enemy Act. In 1940, the option-and-dividend contract binding I.G. Chemie to Farben was terminated — unconditionally, and deliberately so, in order to make the separation credible to American eyes.
This is the point at which the popular telling of this story usually turns cynical, treating the 1940 severance as a backdated fiction — a paper trick designed from the start to be reversed once the war ended. The most thorough independent investigation of the case, Switzerland’s own Bergier Commission, examined the surviving record decades later and reached a more careful conclusion: there was no proof of any secret side agreement promising to undo the split. Farben likely hoped, in a general way, to rebuild the relationship if Germany won the war. But hope is not a contract, and by the time the war turned decisively against Germany, Farben had lost any real ability to enforce one. The severance, in other words, appears to have been genuine — a real transfer of legal control, made under real pressure, with an uncertain and unsecured hope attached to it rather than a guarantee.
The U.S. government seized GAF anyway in 1942, under wartime authority, treating Interhandel’s claim of independence as a cover story rather than a fact. Interhandel sued for the return of its property in 1948. Switzerland, backing its own company, took the matter all the way to the International Court of Justice in 1957 — which ruled the Swiss application inadmissible, sending the dispute back into the American courts where it had started.
▸ Insulation
IV. The Sealed Report
Here the story’s real insulation layer appears — and it isn’t the one most retellings reach for. It isn’t bearer shares or numbered accounts. It’s a government audit.
In 1946, Swiss authorities commissioned an internal investigation — later known as the Rees Report — into exactly how close the ties between Farben and its Basel holding company had remained through 1940 and after. The report gathered substantial material on the relationship. Its conclusions, however, were hedged rather than definitive. The Swiss government nonetheless represented publicly, for years afterward, that the report had cleared the separation as genuine — a characterization the Bergier Commission later found did not accurately reflect what the report actually said.
After Union Bank of Switzerland absorbed Interhandel in 1967, UBS pressed Swiss authorities to keep the Rees Report sealed in the federal archive. The likely reason had little to do with the original 1940 question. Releasing the report risked exposing that the Swiss government itself had misstated its findings for two decades — a disclosure that would have weakened Switzerland’s diplomatic position and very possibly made the case more expensive for the bank that now owned the claim. The insulation, in its final and most durable form, was protecting an institution from its own earlier description of the evidence — not protecting the evidence from the institution.
The report that could have settled the argument was not hidden to win it. It was hidden because losing the argument had become less costly than admitting the argument had been mischaracterized.
V. The Settlement
The endgame, when it finally came, was neither clean nor especially dignified. In late December 1962, a separate Standard Oil tax claim against Interhandel surfaced and nearly wrecked a settlement years in the making — prompting Attorney General Robert Kennedy to summon the lead American negotiator for what he reportedly called a “blanket party.” The final terms were worked out that spring through direct, personal negotiation between Kennedy and UBS chairman Alfred Schaefer. When Schaefer noted that two million Swiss citizens were watching how the deal turned out, Kennedy is said to have replied that one hundred and ninety-nine million Americans were watching him.
The settlement split future proceeds from a sale of GAF: roughly 60 percent to the United States, the remainder to Interhandel. When GAF was finally auctioned in 1965, Interhandel’s share came to approximately $122 million — a figure that, after currency conversion, made it one of the largest single recoveries in the history of enemy-property litigation. At a press conference afterward, a reporter asked Kennedy directly whether two decades of government assurances that Interhandel was a Farben front had simply been wrong, or whether the settlement reflected Swiss diplomatic pressure instead. Kennedy’s answer offered nothing: it was, he said, an equitable agreement. Two years later, UBS absorbed Interhandel outright, closing the file for good — except for the report still sitting, sealed, in the federal archive.
FSA Wall — A Correction Made in the Open
Earlier research material reviewed for this piece described Interhandel as a deliberately fabricated front company from inception, named a $24 million figure as the eventual settlement amount, and credited the law firm Sullivan & Cromwell with running Interhandel’s post-war litigation. None of those three claims survives contact with the primary record.
The $24 million was a separate Standard Oil tax claim, not the settlement. The actual recovery was roughly $122 million. And while Sullivan & Cromwell partner Allen Dulles did have real, well-documented pre-war legal ties to General Aniline & Film as Farben’s U.S. subsidiary, the firm of record in Interhandel’s actual post-war litigation was Davis, Polk & Wardell, with attorney John J. Wilson as lead counsel. Most significantly, Switzerland’s own Bergier Commission — the authoritative historical inquiry into this case — explicitly concluded that I.G. Chemie was not a front organization at its founding, and found no evidence that the 1940 severance was secretly conditional.
We are naming this correction rather than quietly fixing it, consistent with this archive’s standing practice: a wrong number, once published, should be findable next to the correction, not erased in favor of it.
What actually happened to Interhandel is a less satisfying story than the one usually told about it, and a more honest one. There was no single mastermind whose foresight outwitted two governments for thirty years. There was a holding company built for ordinary commercial reasons, repurposed under real wartime pressure, fought over in good faith and bad by people on both sides who could not fully prove their own case — and an answer that existed in an archive the whole time, sealed not to protect the original secret, but to protect the people who had already gotten the secret wrong in public.
