This is a pretty strange poll...
If we look at the development of calculus the key role was probably played by Archimedes' discovery of how to square a parabola segment.
In the 19th century Riemann and Galois perhaps had the most significant legacy.
In the 20th century no one was nearly as influential as Grothendieck.
