How a group of Manhattan Project scientists turned a clock into a global warning
In short: Founded in 1945 by scientists who built the atomic bomb, the Bulletin of the Atomic Scientists was created to warn humanity about the nuclear arms race. Its most famous creation, the Doomsday Clock, serves as a symbolic metaphor for the existential threats posed by nuclear weapons, climate change, and disruptive technologies.
The Bulletin began as an emergency initiative by scientists from the University of Chicago, including Eugene Rabinowitch and Hyman Goldsmith, who felt a moral imperative to educate the public on the dangers of the Atomic Age. Initially titled the Bulletin of the Atomic Scientists of Chicago, the publication dropped the city name in 1946 to reflect its broadening scope and international contributor base. Over the decades, it has featured insights from luminaries such as Albert Einstein, J. Robert Oppenheimer, and Bertrand Russell, evolving into a nonprofit organization that bridges the gap between complex scientific realities and global policy.
In 1947, artist Martyl Langsdorf designed the Doomsday Clock to convey a sense of urgency regarding nuclear devastation. The clock is not a predictive tool but a symbolic representation of manmade threats. The Science and Security Board adjusts the minute hand annually based on international developments. While the clock was set to 17 minutes to midnight in 1991 following nuclear arms reduction agreements, it has trended closer to midnight in recent years, reflecting heightened global instability.
The organization's influence extends beyond its iconic clock. It was instrumental in forming the Pugwash Conferences on Science and World Affairs in the 1950s, fostering international dialogue on nuclear proliferation. Today, the Bulletin operates as a digital-first publication, with its academic journal maintaining a 2023 impact factor of 1.9. Through its Science and Security Board, the Bulletin continues to synthesize data on climate change, nuclear weaponry, and emerging technologies to provide a sobering, nontechnical assessment of the risks facing humanity in the 21st century.
The Bulletin's historical records are preserved at the University of Chicago, and its archives provide a comprehensive look at the evolution of scientific concern regarding global security. By maintaining its independence and commitment to public education, the organization remains a vital voice for scientists who believe that understanding the consequences of technological progress is essential for survival.
