It was the opening gambit of World War Two in Europe. After trying to press its geographical claims (especially to the Danzing corridor) through political means, Hitler decided to go ahead with an invasion of Poland.
Two weeks later, in accordance with the provision of a secret agreement between Nazi Germany and Soviet Russia, Stalin’s forces invaded Poland from the east, and within a month, the nation was conquered entirely, and partitioned between the two invaders.
But the war wasn’t over. Poland had allies – France, Britain and Britain’s Empire all declared war on Germany on September 3. World War Two had begun in Europe.
The Bulletin of the Atomic Scientists is one of the world’s most prestigious scientific publications in the world. Its first issue, published on December 10, 1945, was only two pages in length. It has grown since then.
In June of 1947, its cover featured, for the first time, what became known as the Doomsday Clock. This would become the regular cover for Bulletin, throughout the run of its print edition, and even today’s online version, which has no cover per se, maintains the clock. The number of minutes before midnight – measuring the degree of nuclear, environmental, and technological threats to mankind – is periodically corrected; when it was first published, the clock was set at seven minutes to midnight.
In September of 1953, Volume IX, Number 7, the Clock was set to 2 minutes to midnight – the closest they had ever been. The hands remained here until January of 1960, and have never again been set so close to midnight.
