Why an Index Matters in a Biography Like This

Unlike a novel, The Man Who Knew Infinity is a densely sourced historical work. Kanigel interviewed dozens of surviving relatives, pored over letters from the Cambridge archives, and translated complex mathematical ideas into prose. The index serves three critical purposes: Origin: Born December 22, 1887, in Erode, Tamil Nadu, India

1. Chronological Navigation: Jump directly to Ramanujan’s voyage to England in March 1914 without rereading the first 200 pages.
2. Conceptual Clustering: See how the theme of "intuition vs. proof" appears across Ramanujan’s childhood (page 42), his collaboration with Hardy (page 174), and his final notebooks (page 345).
3. Name Recognition: With dozens of minor mathematicians, Indian civil servants, and Cambridge dons, the index prevents confusion between figures like E. H. Neville and G. H. Hardy.
