`The man sitting next to the podium appeared to be very old, at least in the eyes of the members of his audience, most of whom were very young.'
GH Hardy, the famous mathematician, is about to receive an honourary degree from Harvard at the start of this novel. But he knows that his audience will want to hear about Ramanujan, the Indian clerk of the title, a mathematical genius and Hardy's protégé. In his speech Hardy says that his association with Ramanujan was `the one romantic incident' in his life.
I'm not quite sure what I think about this genre of historical fiction based on real lives but Leavitt is very good at it. It's well researched, convincing and engaging. It's good on the maths and the search for the proof of Riemann hypothesis for prime numbers and of Cambridge and London just before and during the first world war. It examines class and also the homosexual world at that time - DH Lawrence and Wittgenstein both make an appearance and both seem repulsed by what they see of Cambridge gay society. Bertrand Russell, JM Keynes, Lytton Strachey and Rupert Brooke are fellow apostles, the not so secret society of which Hardy is a member. They have minor roles but help to place this novel in terms of time and place.
Ramanujan and Hardy come from different worlds but both can enter a world of maths which most of us cannot inhabit `a world remote from religion, war, literature, sex, even philosophy' says Hardy and he also states `a slate and some chalk. That's all you need'. Leavitt does a pretty good job of giving us a feel for that and the excitement that goes with it. Except that it turns out that isn't all either of them need. Ramanuajn gets ill in England; it's difficult for him to follow his strict vegetarian diet. He wants the honours and prizes he hasn't had to date. Hardy has fulfilment in his working partnerships with Littlewood and Ramanujan but can't extend that into his personal relationships. It's a strange era, at once more formal than ours and yet one in which friendship between grown men can be expressed by them walking hand in hand through the streets.
Overall, The Indian Clerk is very good but not fully successful - perhaps because Leavitt had to follow the facts or perhaps because Ramanujan remains such an enigma - but it's well worth the read and you even feel like you've grasped some of the maths.
