German physical chemist who provided the first chemical evidence of nuclear fission. Hitler, fortunately, did not grasp the destructive potential of this discovery—there is some evidence that Hahn kept him deliberately in the dark—and Hahn spent the war years doing small experiments on the industrial use of atomic energy. Won the Nobel Prize for Chemistry in 1944. Vintage matte-finish 2.5 x 4 photo, signed in the lower border in fountain pen. In fine condition. R&R COA.
