The Atomic Bomb in Images and Documents

Book excerpt: Samuel S. Kloda spent more than 40 years meeting with the scientists who built the first atomic bombs, and the crews that delivered them to Hiroshima and Nagasaki. Those conversations encouraged him to search archives throughout the U.S. Newly unearthed documents were brought to former members of the Manhattan Project or the 509th Composite Group, who were always willing to autograph and recount the details of these artifacts. Most of the major books on the Manhattan Project were published before 1973. In the years that followed, newly declassified documents became available and showed that many authors had included huge inaccuracies. Richly illustrated with important documents and photographs, Kloda's chronicle of the dawn of the atomic age sets the record straight on one of the greatest scientific advancements of all time. Readers will see how a single letter from Albert Einstein to President Franklin Roosevelt in 1939 led to the formation of the Advisory Committee on Uranium and, within six years, to the secret Manhattan Project employing more than 100,000 men and women.
