Jean Ziegler, the man who dared to bite the hand that fed him

02.10.2026 – Stéphane Herzog

The outspoken socialist Jean Ziegler has died aged 92, after succumbing to a long illness. Known throughout the world, he was both loved and hated in his native land. He helped end banking secrecy and shone a spotlight on how hunger was used as a political weapon.

Erica Deuber Ziegler welcomes us to her beautiful home, in the hills of the village of Russin, in Geneva. She is the widow of Jean Ziegler, who died in June of Parkinson’s disease, which he called “that crap”. After the funeral, which was held in St. Peter’s Cathedral to the sound of the Internationale, it is time for her to take care of his legacy. The art historian, a former deputy of the Grand Council of Geneva who had met the Berne-born sociologist when typing up the proofs of his works, is sorting through hundreds of cardboard boxes. Some of it will be entrusted to the Federal Archives. The living room table is covered with photocopied obituaries of the former UN Special Rapporteur on the right to food worldwide. “A voice against global inequalities” was the headline in “Vatican News”. “The revolutionary in a bespoke suit,” wrote the “NZZ”.

There is a wicker basket containing over 300 letters of condolence, including one from former SVP Federal Councillor Christoph Blocher. “They didn’t agree on anything, but they respected each other,” says Deuber Ziegler. The author of “Une Suisse au-dessus de tout soupçon” (1976) [A Switzerland above all suspicion] and “La Suisse lave plus blanc” (1990) [Switzerland washes whiter] was an uncompromising character. His last word was a loud “no” to a nurse who was trying to get him to eat, according to his widow. What impact did Jean Ziegler have on Swiss politics? “He played a fundamental role, not from a legislative perspective but by saying publicly what nobody else had dared to say up till then,” in the view of professor of political science Pascal Sciarini. He spoke out about Nazi gold in Switzerland, unclaimed funds, dictators’ dirty money kept in Swiss bank accounts under the guise of banking secrecy.

“He picked the wrong heroes.”

And “man-made” hunger. Some say that the Geneva native, who travelled to some of the poorest regions on the planet, had no qualms about “biting the hand that fed him”, the hand of Swiss prosperity, partly due to banks. “His knack for finding a killer phrase, and for exaggerating, made him popular amongst the converted and an opponent who needed to be silenced to the targets of his criticism,” says the political scientist, who does, however, point out that repeated inaccuracies in Ziegler’s statements sometimes undermined their impact.

“Killing” the father

Born in Thun to a Calvinist father, who was a judge and artillery colonel, Jean Ziegler was aware of poverty from a very young age. During the Second World War, “he saw poorly dressed children placed with families. What should we do? he asked his father, who replied: Mach di Sach, which translates as everyone should mind their own business,” recalls Erica Deuber Ziegler. The Calvinist concept of predestination sickened him. Jean Ziegler went on to “kill” his father by converting to Catholicism and becoming a Marxist. This from the man whose maternal grandfather was one of the founders of the Swiss People’s Party.

In 1961, after obtaining a doctorate in law and becoming a lawyer, Jean Ziegler travelled to the Congo as a UN special envoy. This would give rise to his interest in decolonisation and his approach of developmental sociology. In Paris, he rubbed shoulders with Sartre and Simone de Beauvoir. Rebellious, audacious and “immune to criticism”, according to his friend, property developer and author Metin Arditi, Ziegler drew the ire of the courts. In 1991, the Swiss Parliament voted to lift his parliamentary immunity, paving the way for nine lawsuits for defamation, which he lost. None of this would prevent the sociologist being re-elected, in the same year, to the National Council. He moved in with his second wife in her house in Russin, where the bailiffs came to call more than once, the art historian remembers.

The “NZZ” called Jean Ziegler “The revolutionary in a bespoke suit”.

A high point of his career was when he met Ernesto Che Guevara in Geneva in 1964. “Jean was called to act as a guide,” his widow recalls. For 10 days, the sociologist, who became vice-chairman of the United Nations Human Rights Council Advisory Committee in 2009, took Che around Geneva and explained the Swiss political system to him. Jean Ziegler offered to accompany him to Cuba. “The head of the monster is here. You need to fight in this city,” Che commanded. “It was as if Christ had spoken to him,” Erica Deuber Ziegler recalls.

Denouncing banking secrecy

One of the criticisms levelled against Jean Ziegler was that he met with revolutionaries who became dictators: Fidel Castro, Robert Mugabe, Muammar Gaddafi, Hugo Chávez. “Jean met Gaddafi three times to ask him about the situation of the populations of the Sahel. He said that was once too many,” his widow says. “He stood with the people living under dictatorships,” comments the former Social Democratic Party Federal Councillor Micheline Calmy-Rey, who praised his courage and his ability to condemn the hypocritical actions of Switzerland. One such example was in 1998, when he appeared before the US Senate Banking Committee to argue the idea that only economic sanctions would force Swiss banks to repay the funds from unclaimed accounts.

“When he denounced banking secrecy, he did the banks a favour, as they realised that they would have to make changes in pursuit of excellence,” believes Metin Arditi. Former FDP Federal Councillor Pascal Couchepin is of a different view: “He saw himself as the representative of the third world, but he picked the wrong heroes. Ultimately, Jean Ziegler bequeathed Switzerland a rather modest legacy,” he stated to the press after Ziegler’s death. The barb brings a smile to Erica Deuber Ziegler’s face as she points out, among other things, that her husband was known all around the world.

On 1 August, in the small municipality of Choulex (Geneva), his son, playwright Dominique Ziegler, made a speech at the invitation of the local authorities. “For the past 10 years, UBS has contributed 211 billion US dollars to projects connected with oil and gas. It’s absolutely insane,” he told the villagers, following in the footsteps of his late father.
