These measures were sufficiently effective in the
last six years of peace to force roughly half of
German Jews to emigrate (and the privileged, e.g.
internationally recognised researchers, were the
most able to get admission somewhere else.) So no
major effect on S&T seems likely.
While most of the existing Jewish elite in Mitteleuropa
got away early, the great pool of middle and east
European Jewry from which this elite was drawn did not.
The survivors of this population later provided many
successful scientists and technologists in the USSR
One might also look at the achievements of east European
Jewry in the US: many highly successful American Jews,
including scientists and technologists, lost numerous
relatives to the Holocaust. Unless one wants to believe
that it was usually the smart ones in the family who
emigrated in 1890-1930, there is no reason to think that
that those who stayed in Europe would have contributed
