Are any of you old enough to recall the Cuban Missile Crisis in 1962? The world came close to a nuclear war and kids like me participated in nuclear attack drills in which we were instructed to hide under our desks at school. I still remember the sound of the air raid sirens. This was very scary stuff. Starting with the Cold War in the 1950s and the creation of the hydrogen bomb tens of thousands of Americans built fallout shelters to ensure survival after a nuclear attack.
In 1959, the government published and distributed millions of copies of a 32-page booklet called The Family Fallout Shelter. It included step-by-step instructions for building the Concrete Block Shelter, a cube constructed of concrete block and mortar.
Shelter mania continued until the early 1960s when people lost faith that a shelter could protect them from a nuclear holocaust.Link
