Dr A.P.J. Abdul Kalam was born and raised in Rameswaram, Tamil Nadu. His passion for learning led him from humble beginnings to the prestigious Madras Institute of Technology, where he became an aeronautical engineer. After a brief stint at the Defence Research and Development Organization of India (DRDO), Dr Kalam joined the Indian Space Research Organization (ISRO), where he became the project director for India's first Satellite Launch Vehicle (SLV-3), which placed the Rohini satellite in orbit. Later, he rejoined the DRDO and played a pivotal role in the development of India's ballistic missile systems. He eventually rose to become the scientific advisor to the defence minister of India and was later appointed as principal scientific advisor to the Government of India, with the rank of a cabinet minister, involved in policy and strategy to transform India into a developed nation and a nuclear weapons state. Dr Kalam is the recipient of many national and international awards, including honorary doctorates from forty-eight universities all over the world. He received India's highest civilian award, the Bharat Ratna, in 1997. Widespread recognition, coupled with his extensive national service, made Dr Kalam a popular choice for high office, and he became the eleventh president of India in 2002. His popularity has endured, and he is still affectionately called the 'people's president' for bridging the gap between high office and the common people. In addition to the autobiography Wings of Fire, Dr Kalam has written many books, and most of them are household names: India 2020: A Vision for the New Millennium, Ignited Minds: Unleashing the Power within India, Envisioning an Empowered Nation: Technology for Societal Transformation, Indomitable Spirit, Target 3 Billion: PURA: Innovative Solution Towards Sustainable Development, Turning Point, Governance for Growth in India, A Manifesto for Change and Beyond 2020: A Vision for Tomorrow's India. *** Arun Tiwari did his master's in mechanical engineering from G.B.
