Hardy to Ramanujan
Dated 26-3-1913

In quick succession, Ramanujan received in the next three months, four long letters from Hardy, in which Hardy wrote plainly about what had been proved or claimed to have been prove by Ramanujan. He clearly communicated his genuine anxiety to “see what can be done to give you [Ramanujan] a better chance of making use of your obvious mathematical gifts”. And Ramanujan in return was willing to place unreservedly in "Hardy’s hands" all that he had.
