Overview

• Walker’s July 2025 book draws on over 11,600 declassified pages at the Deutsches Museum in Munich
• German scientists pursued atomic research with high urgency and matched U.S. progress until mid-1942
• Wartime material shortages, Allied bombings and redeployment of researchers to the front halted the Nazi bomb effort
• Emigration of key physicists like Einstein and Meitner did not weaken Germany’s program but aided the U.S. Manhattan Project
• U.S. nuclear research ultimately culminated in the only wartime use of atomic bombs at Hiroshima and Nagasaki
