I have read "Alan Turing: The Enigma" by Andrew Hodges, which was excellent, both in the biographical details and the mathematical details.
I myself being too obsessed with mathematics loved this biography of Ramanujan - The Man Who Knew Infinity: A Life of the Genius Ramanujan. ISBN:0671750615
I need to read the book on Ramanujan you mentioned, though.
why would anyone care to read "fictions" about sexual inclinations of big minds (Hardy and undoubtedly huge mind of Ramanujan) when we don't even know/understand completely the works of these great minds?
