Virtual Tour: Turn Back the Clock
How the Bulletin of the Atomic Scientists got its start
In the aftermath of World War II, a group of Chicago scientists who helped build the world’s first atomic bomb realized they could no longer “remain aloof to the consequences of their work.” They founded the Bulletin of the Atomic Scientists in December 1945 to inform people about the “horrible effects of nuclear weapons and the consequences of using them.”
Today, more than 70 years later, the Bulletin and its iconic Doomsday Clock continue to provide a platform for dialogue and debate among scientists, policy makers and the public about nuclear weapons, climate change and other consequential scientific and technological issues that pose a risk to human survival.
As the Bulletin’s founders recognized, great breakthroughs often pose great risks. Human ingenuity inspires our most powerful technological innovations. It takes all of us, with our creativity and our commitment, to build a safer world.
Founded more than 75 years ago, the Bulletin has evolved from a local mimeographed newsletter into a global digital presence. It continues to fulfill its founders’ purpose: provide a forum for open discussion around the uses of emerging technologies that can pose significant risks to life on Earth as we know it.
