CHICAGO (AP) — The Doomsday Clock turns 75 this month. It is the image commissioned from Martyl Langsdorf in 1947 by scientists who were awed and frightened by the power of the atomic bomb they had created.
Langsdorf’s idea was a stripped-down clock with markings in just the last quarter before midnight, which signified disaster. She put the minute hand at seven minutes to 12.
The Bulletin of Atomic Scientists adjusts it each year based on world events and tensions. It now stands at 100 seconds to midnight.
