Kind of a soft question. More out of historical curiosity than really seeking an affirmative answer.
Reading up a little bit, over time, I am increasingly tempted to believe that, the Soviet mathematician Andrey Kolmogorov is not celebrated as much as an equivalent European or American genius of similar calibre. His contribution to modern science, including probability theory and computational complexity are not often talked about as much in the mainstream. Is this a mere coincidence or just that his work missed the visibility aspect, because of the geo political situation of the 20th century? Isn't Kolmogorov, one of the top 3 applied mathematician of 20th century?
