Alberto Calderón and Antoni Zygmund
Alberto Pedro Calderón (1920 – 1998) was an Argentinian mathematician. Calderón's work ranged over a wide variety of topics: from singular integral operators to partial differential equations, from interpolation theory to Cauchy integrals on Lipschitz curves, from ergodic theory to inverse problems in electrical prospection.
Antoni Zygmund (1900 – 1992) was a Polish mathematician. His work has had a pervasive influence in many fields of mathematics, mostly in mathematical analysis, and particularly in harmonic analysis. Among the most significant were the results he obtained with Calderón on singular integral operators.

In mathematics, the Calderón–Zygmund lemma is a fundamental result in Fourier analysis, harmonic analysis, and singular integrals.

Godfrey Harold Hardy (1877 – 1947)
was an English mathematician, known for his achievements in number theory and mathematical analysis.
Hardy was one of the first to do important work on the Riemann Hypothesis when he proved that the zeta functio Zeta(s) = Zeta(sigma + it) has infinitely many zeros on the critical line sigma = 1/2.
