"He looks rather ill," G.H. Hardy wrote when he first saw the photo in 1937, "but he looks all over the genius he was."
Re. the passport photo of Ramanujan in 1919 on his way back to India.
He combined a power of generalization, a feeling for form, and a capacity for rapid modification of his hypotheses (...) He was a man who could work out modular equations and theorems... to orders unheard of, whose mastery of continued fractions was... beyond that of any mathematician in the world, who had found for himself the functional equation of the zeta function and the dominant terms of many of the most famous problems in the analytic theory of numbers.
G. H. Hardy about Ramanujan mathematical skills
I have never met his equal, and can compare him only with Euler or Jacobi.
G. H. Hardy about Ramanujan
Euler and Ramanujan are mathematicians of the greatest importance in the history of constants (and of course in the history of Mathematics...)
