King Of Infinite Space by Siobhan Roberts

Donald Coxeter, the Man Who Saved Geometry

A lively biography of the brilliant and eccentric British mathematician John Horton Conway, tracing his life from a curious child to a leading figure whose playful, iconoclastic approaches produced major discoveries — from the Game of Life cellular automaton to deep advances in group theory, knot theory, and the invention of surreal numbers. The narrative interweaves clear, accessible explanations of key mathematical ideas with vivid anecdotes about his personality, teaching, collaborations, and the creative culture that shaped his unconventional contributions to modern mathematics.
