Srinivasa Aiyangar Ramanujan

"Almost a century after his death, it was said of him, "Ramanujan was a mathematician so great that his name transcends jealousies, the one superlatively great mathematician whom India has produced in the last thousand years. His leaps of intuition confound mathematicians even today, seven decades after his death. His papers are still plumbed for their secrets. His theorems are being applied in areas scarcely imaginable during his lifetime." (quoted from Kanigel's biography, "The Man who knew Infinity", p.3)

Ramanujan, Srinivasa, 1889–1920, Indian mathematician. He was a self-taught genius in pure mathematics who made original contributions to function theory, power series, and number theory with the training gained from a single textbook. He was invited to Cambridge by G. H. Hardy, with whom he collaborated, and continued there his work in number theory. He died of tuberculosis.
