Ramanujan gave his Notebooks to Mr. R. Radhakrishna Ayyar (Advocate) a classmate in Pachaiyappa’s college (1906-1907), before he returned to Kumbakonam due to ill-health – for safe keeping. Ramanujan told him: “If I die, please hand them over to Singaravelu Mudaliar or to the British Professor – Edward B. Ross – of the Madras Christian College”. (Ref. MJ91, page MJ7 in “Ramanujan, the Man and the Mathematician”, by S.R. Ranganathan, Asia Publishing House, 1967).
