When was the Doomsday Clock, representing humanity's closeness to global catastrophes caused by human-made technologies and environmental crises, first introduced by the Bulletin of the Atomic Scientists?
The Doomsday Clock was created in 1947, two years after the atomic bombings of Hiroshima and Nagasaki. The concept was developed by scientists who worked on the Manhattan Project and were deeply concerned about the nuclear arms race following World War II. Artist Martyl Langsdorf, a member of the Bulletin, designed the original clock.
