Hartwig's interest in astrophysics and nuclear physics. With the outbreak of war, joins the Army nuclear physics research group under Kurt Diebner. The first uranium machine (G-I) experiment at the Army Weapons Testing Lab in Berlin-Gottow. Radiation protection. Tension between the research groups under the direction of Diebner and Werner Heisenberg. Question of internal uranium machine design, cubes or layers? The second uranium machine (G-II), a lattice of metal uranium cubes immersed in heavy water, a great success. The last years of the war, evacuation and survival. Occupation by the Allied armies, life in the Russian-controlled eastern zone of Germany.
