I read the new york times article. I get the feeling that it draws too much attention to the personal, emotional relationships of Hardy, Ramanujan and others and dilutes the genius each one of them were. It definitely would be a good read once you are through with the brief introduction into their professional lives.

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
