During the Revolution, and preceding it, it turns out that many scientists were involved or even instrumental in the social progress that occurred. The simple act of imposing the metric system was meant as a way to eradicate the imperial in "imperial system". The Enlightenment caused the rise of many ideas of equality that can be said to have triggered the Revolution.
Of course, the extremes of the Terror also caused some scientists that were not deemed invested enough to lose their head, such as Lavoisier, the man that proved the conservation of mass. It should be noted that the government apologised a year or so later.
Historically, many of Stalin's actions were not seen keenly in France, including Stalin's Gulags, his pact with Hitler, and over the cold war, his territorial aggressivity over the USSR's satellite countries. You may note that France was very decidedly on the other side of the Iron Curtain.
There definitely were quite a few socialists, there were a few communists, there probably were few Leninists, but I doubt there were any Stalinists. I'd be interested in the scientist's name if you found one.
But my point is rather that being good at math and at creating mathematical representations of nature doesn't qualify someone to make decisions on how other people should live their life.

As it reminds us that the pursuit of scientific knowledge can often distract brilliant people from addressing social problems. I wonder if the glut of research scientists is one of the mechanisms by which the status quo is preserved.
