A bit tangential here, but our calculus/math analysis professor actually told us that the Russian and later Soviet math school drew a lot from the French, although, he might have been biased due to his apparent partiality towards Bourbaki. According to him, the university level math was taught exclusively in French during the Tsarist times, and they had some troubles coming up with Russian terminology when Soviets ordered all teaching to be done in Russian.
