Swiss Mathematician (1707-1783) Euler made large bounds in modern analytic geometry and trigonometry. He made decisive and formative contributions to GeoMetry, CalcuLus and NumberTheory. In number theory he did much work in correspondence with Goldbach. He integrated Leibniz's DifferentialCalculus and IsaacNewton's method of fluxions into mathematical analysis. In number theory he stated the PrimeNumberTheorem and the LawOfBiquadraticReciprocity. Copied and wikified from http://www.math.wayne.edu/~zhihui/Euler.html See there for more details.
