1945 : as apogee AND nadir of Modern Science

Hitler may have successfully convinced his most rabid followers that the murder of every last Jew in Europe was a fitting consolation prize for his failure to deliver up western Russia as the new frontier for the Aryan super race in 1941.

But the rest of humanity regarding Auschwitz as a particularly (and peculiarly)  modern and scientific crime made it particularly hard for modern scientists in the rest of the world to present their continuing support of eugenics as the public face of postwar biology.

Still Auschwitz in the end proved a godsend to Oswald Avery's 1944 reductionist claims that Free Will didn't really exist but was simply manipulated by the chemical workings of a simple molecule called DNA.
