The atomic age began with the US dropping the first atomic bomb dubbed “Little Boy” on August 6, 1945, on the Japanese city of Hiroshima, after its July 16 pre-dawn birth in successful testing at Alamogordo, New Mexico. Three days later, on August 9, 1945, the second bomb – “Fat Man” – was dropped on Nagasaki, incinerating the city and its unexpecting inhabitants. Their combined devastation was unimaginable.
