Since Hua Loo-Keng held a dominant position within contemporary mathematics in China, this book can also be read as a valuable piece of history of the development of modern Chinese mathematics. Besides giving a visual account of Hua's research work, and of his attitudes and philosophy in the areas of learning and mathematics education, the book also paints a picture of his many years of work on the popularisation of mathematics in China. It includes a detailed description of the terrible conditions scientists had to endure during the war periods, particularly during the "Cultural Revolution". This definitive biography is written by Prof. Wang Yuan, one of Hua's distinguished students, who worked closely with Prof. Hua for over thirty years.
