Tech, tech, boom: The revolution begins
From atom bombs and space rockets to drones and tape recorders, every U.S. president from the post-World War II era had some piece of technology or item that helped defined their time in the Oval Office.
To celebrate President's Day in the U.S., we've collected the past dozen American heads of state and picked out the item, tech, gadget (or weapon) that defined their reign as the commander-in-chief.

Franklin D. Roosevelt: The Manhattan Project
While it was his successor, Harry S. Truman, that actually gave the orders to deliver the only nuclear weapons ever used in combat, it was Roosevelt who ordered the beginning of the Manhattan Project. The project would bring together some of the finest minds in nuclear physics research to build the first atomic bomb, which would be tested extensively and used on Japan, twice, that would end the second largest war in modern history.
In spite of the painful ending to the war, the research conducted by the world-leading experts led to a massive push in nuclear medicine and power, which ultimately helped form the nuclear power networks we have today.
