Hitlers Bombe
 Under supervision of the SS, from 1944–45, German scientists in Thuringia tested some form of "nuclear weapon", possibly a dirty bomb (for the differences between this and a standard fission weapon, see nuclear weapon design). Several hundred prisoners of war are alleged to have died as a result. Karlsch's primary evidence are alleged vouchers for the atomic weapon attempts, a preliminary plutonium bomb patent from the year 1941 (which had been known about, but not yet found), and conducted industrial archaeology on the remains of the first experimental German nuclear reactor.
