As chief of the country’s defence research and development programme, Kalam demonstrated the great potential for dynamism and innovation that existed in seemingly moribund research establishments. This is the story of Kalam’s rise from obscurity and his personal and professional struggles, as well as the story of Agni, Prithvi, Akash, Trishul a nd Nag - missiles that have become household names in India and that have raised the nation to the level of a missile power of international recokoning. At the same time as he has helped create India’s awesome weaponry, Kalam has maintained the ascetic rigour of his personal life, working 18 hours a day and practicing the veena. With characteristic modesty, Kalam ascribes the greatness of his achievement to the influence of his teachers and mentors. He describes the struggles of his boyhood and youth, bringing alive everyday life in a small town in South India and the inspirational role of educators. He describes the role of visionary Indian scientists, such as Dr Vikram Sarabhai, and of the creation of a coordinated network of research institutions. This is also the saga of independent India’s struggle for technological self sufficiency and defensive autonomy – a story as much about politics, domestic and international, as it is about science
