The first atomic bomb used in war was made from uranium-235 and was dropped on Hiroshima on August 6, 1945. The isotope of uranium needed for the bomb was separated in Oak Ridge, Tennessee, as part of the Manhattan Project. My father is Hubert P. Yockey, and he is a nuclear physicist who studied under Robert Oppenheimer and Ernest Lawrence at the University of California at Berkeley. After earning his Ph.D., he was sent to Oak Ridge. That is where he met my mother.
I will update this tomorrow with a video of my father.
