How did the world’s first atomic bomb get its name? Looking back on the Trinity test on its 76th anniversary

The world’s first-ever atomic bomb is called The Gadget. It was detonated in the New Mexico desert on July 16,1945 during the Trinity test, verifying that an implosion-type plutonium bomb would be successful when released above Nagasaki just weeks later. That atomic bomb was called Fat Man and it was a weaponized version of the Trinity device of The Gadget. According to the longtime lore, the bulbous-looking Fat Man bomb’s name was inspired by British Prime Minister Winston Churchill. After the Thin Man bomb, whose moniker was inspired by the U.S. President Franklin Roosevelt, didn’t come to fruition, the gun-type uranium atomic bomb named Little Boy was developed. It was likely dubbed as such because it was smaller in size.
