Oppenheimer: The Library’s Collection Chronicles His Life

Julius Robert Oppenheimer, leader of the Manhattan Project and father of the atomic bomb, is the subject of “Oppenheimer,” due out in theaters tomorrow.

His morally complex, intellectually voracious life has been the subject of an astonishing amount of worldwide scientific, cultural, political and historic interest since 5:29 a.m., July 16, 1945, when the first atomic bomb was detonated in New Mexico, ushering in the nuclear era. The test site was named Trinity and the plutonium device was called Gadget. The scientific director of the project, the American who beat the Germans and the Russians to create the world’s most devastating weapon, was J. Robert Oppenheimer.

Weeks later, the bomb was put to devastating use in Hiroshima and Nagasaki.

So cataclysmic were the bombs that the world was permanently altered by the work Oppenheimer led at what is now known as the Los Alamos National Laboratory in New Mexico.

“I think it is true to say that atomic weapons are a peril which affect everyone in the world,” Oppenheimer said in a speech in November 1945, when the atomic age was just a couple of months old.
