29 January 2026 – Born from a convergence of resistance, diplomacy and long-range imagination, the Club of Rome emerged in the late 1960s as a radical response to a world accelerating toward crisis. This article traces how Aurelio Peccei’s humanistic vision and Alexander King’s strategic pragmatism fused into a new form of global thinking: one that refused disciplinary silos, institutional rigidity and short-term policy cycles. The Club of Rome took shape as an “invisible college” committed to understanding the world as an interconnected whole. Following its early gatherings in Rome and Bellagio, its deliberate informality and the commissioning of The Limits to Growth, this account captures the fragile, experimental beginnings of an organisation that dared to question the assumptions of modern progress and plant the intellectual seeds of planetary responsibility.
Behind the idea
The Club of Rome was born from an encounter between two men who shared a sense that the world was accelerating toward crisis. Aurelio Peccei, an Italian industrialist shaped by war and Alexander King, a British scientist turned international policy strategist, were not immediate allies by background. Peccei came from resistance networks and post-war reconstruction; King came from OECD science diplomacy. Together, they built a think-tank that questioned the very foundations of modern progress.
Peccei’s life prepared him to read global systems differently. A resistance fighter during World War II, he was imprisoned and tortured, then returned to the corporate world with a conviction to secure humanity’s future. Working with Fiat, Italconsult and development initiatives in Latin America, he saw how the overall consequences of technological expansion, inequality and environmental depletion were being ignored. His idea of to the ‘problematique’ — a tangle of global problems that could not be solved in isolation — became the backbone of his worldview. He later expanded on these reflections in his autobiography, The Human Quality, where he explored the ethical and humanistic dimensions of global change.
A speech that travelled the world
Alexander came in when he read a speech Peccei delivered in 1965 at the National Military College in Buenos Aires entitled “The Challenge of the 1970s for the World of Today” after Dean Rusk, then US Secretary of State had it translated and circulated widely in Washington. It was no standard business or development talk: Peccei warned of a rapidly accelerating techno-scientific revolution and argued that humanity risked being unprepared for its wider consequences. King wrote to Peccei, sharing his admiration and suggesting a meeting, noting that their worries about long-term global issues seemed deeply aligned. Dzhermen Gvishiani, Soviet representative and influential science policy leader, was deeply moved by Peccei’s speech and sought him out for discussions in the USSR. These diplomatic ripples eventually brought Peccei and King together in Paris in 1966. They recognised each other as kindred spirits; both deeply committed to creating a new kind of long-range global thinking that went beyond traditional institutions. Their early conversations and influence echoed through scientific and diplomatic circles, thus pushing forward the need for global action.
The founding moment
In April 1968, Peccei secured funding from the Agnelli Foundation and convened a gathering at the Accademia dei Lincei in Rome, where 36 economists, scientists and officials attempted to map global challenges and potential crises. Peccei had also hoped to present his book The Chasm Ahead (published later in 1969) which sought to bring urgency to the moment. The meeting dissolved into technical disagreements and semantic disputes. However, an impromptu conversation afterward at Peccei’s home still in Rome succeeded where formal debate had not. A small circle including Peccei, King, Erich Jantsch and Hugo Thiemann named themselves the Club of Rome. The name was suggested by Hugo Thiemann who drew inspiration from private clubs and from Rome being a symbolic meeting place. They committed to long-term, global and interdisciplinary study of the problematique. It was followed by a second critical meeting in Bellagio in June 1968 that helped define direction for the Club of Rome. Convened with support from the Rockefeller Foundation, the meeting produced the Bellagio Declaration, an informal consensus that global problems were systemic and required modelling and long-range analysis. The declaration is widely regarded as the actual intellectual launchpad of the Club of Rome.
An “invisible college” by design
Peccei insisted the Club of Rome remain informal, without corporate status or bureaucratic dependence. It operated as what King later called an “invisible college.” It functioned as a “non-organisation” by design which meant no membership list, legal registration, headquarters or formal reporting structure to deliberately avoid political pressure. This was extremely rare for the time and part of why early observers described the Club of Rome as “mysterious”.
Despite invitations, Peccei often avoided formal institutional alignment, wary that international agencies would dilute the freedom to think beyond policy cycles. Following frustration with fragmented expert discussions, King and Peccei jointly pushed for a global model that could integrate population, economy, resources and environment. The initial approach went to Iranian systems analyst Hazan Osbekhan. But when Osbekhan failed to deliver an actionable approach, the Executive Committee proceeded to invite system scientist Jay W. Forrester from Massachusetts Institute of Technology (MIT) to a meeting in Bern in the spring of 1970. Forrester indicted his ability and willingness to make a computer model of global development using his system dynamics methodology.
The Limits to Growth
Peccei and the Executive Committee agreed to fund the endeavour after having spent two weeks at MIT learning more about Forrester’s proposal. The Club of Rome arranged a grant from the German Volkswagen Foundation, which Forrester used to fund a research team in his offices at MIT led by young assistant professor Dennis L. Meadows. The Volkswagen funding allowed the Club of Rome to commission one of the most disruptive studies of the 20th century: The Limits to Growth, authored by Donella H. Meadows, Dennis Meadows, Jorgen Randers and William W. Behrens, based on the efforts of many others in the system dynamics group at MIT. Between 1970–1971, briefings at OECD, MIT and the Smithsonian raised anticipation around the still-unfinished study which made The Limits to Growth an international event before it reached the public.
Peccei championed the report not to predict collapse, but to provoke reflection on long-term planetary limits. Meanwhile, King ensured that governments and international bodies could not ignore it. The report sparked intense criticism from economists and scientists who accused the Club of Rome of alarmism and overlooking innovation, but it also forced global debates to take sustainability seriously and linked its founders to emerging global policy conversations on population, environment and development.
As the Club of Rome grew, tensions emerged. Some members favoured sharper scientific modelling; Peccei insisted on a humanistic and ethical foundation. He believed the challenges required not only new systems thinking but a “revolution of the human spirit.” His conviction often made him emotional, particularly when colleagues tried to minimise the moral dimension of global interdependence. On 14 March 1984, Peccei died, leaving behind a movement still struggling to balance his visionary impulse with organisational demands.
Towards institutional maturity
With his passing, Alexander King became president. Under King, the Club of Rome formalised its structure, established a Secretariat and began developing clearer strategic programs without abandoning Peccei’s vision. King co-authored The First Global Revolution in 1991 with Bertrand Schneider, a report that reassessed the Club of Rome’s mission to emphasise not only environmental and development issues, but governance, education and ethical values. He served as president until 1990 and remained deeply involved in future thinking and global sustainability work even after stepping down. Alexander King passed away on 28 February 2007, at age 98. In his memoir, Let the Cat Turn Round: One Man’s Traverse Through the Twentieth Century, King reflected on his life in science diplomacy and the ideas that shaped his collaboration with Peccei.
Their legacy is beyond organisational and is deeply human. In The Human Quality, Aurelio Peccei wrote with urgency about cultivating the moral courage and inner discipline needed to face global challenges, serving as a reminder that systems only shift when people do. In Let the Cat Turn Round, King offered a more personal chronicle, showing how curiosity and conviction shaped his lifelong engagement with science and society. Together, their reflections form a quiet invitation to meet our moment with the same honesty and resolve, carrying forward the work of building a world that reflects our highest human qualities.
