R.H. Dalitz with Bust of Ramanujan

The renowned Physicist, Prof. R.H. Dalitz (Oxford University), on his visit to the Institute of Mathematical Sciences, Chennai, in February 1996, spent some time with Prof. K. Srinivasa Rao discussing various aspects concerning Raman and Ramanujan the two giants of Indian science, and Chandra who was a personal friend of Prof. Dalitz and in an e-mail (to Dr. K. Srinivasa Rao), dated 29 March 1996, Prof. Dalitz wrote:

I did not succeed in finding Ramanujan's signature in the Royal Society book. The book is indexed, so it is just not there. The reason undoubtedly is that he was ill in that period and could not go to the Royal Society to sign it. There are other examples of well-known FRS's who somehow didn't get their signature into the book. That means that he did not ever attend any meeting of the Royal Society; if he had, they would have brought out the book and not let him go until he had signed. Of course, it was also wartime, which meant that there were as few meetings as possible.
