Homi Jehangir Bhabha was a nuclear physicist who pioneered the Indian nuclear research programme. Often hailed as the father of India’s nuclear power project, his ambition, far sightedness and enterprise shaped the development of modern science in India. Understanding the need for achieving self-reliance, he laid the framework for nuclear research in India by founding theTata Institute of Fundamental Research (TIFR) and the Atomic Energy Establishment, Trombay (AEET), later renamed Bhabha Atomic Research Centre (BARC) in his honour. Bhabha achieved international prominence for his trailblazing studies in the field of Atomic Energy, while his role of scientist-diplomat, handled with aplomb, gained worldwide recognition in the global arena. This compelling monograph brings to light the life and times of Homi Jehangir Bhabha. It outlines the story of his life, his early work on cosmic rays, which remained a lifelong obsession, his struggles to translate theories into experiments, and his achievements. This deeply evocative work portrays Bhabha’s visionary foresight in anticipating the urgent need for high-quality facilities in India to pursue research on nuclear energy. It also speaks of his passionate interest in art and architecture, drawing and painting, and his love for classical music, which made him stand out as a renaissance man among scientists. Comprehensive and reflective, this monograph encapsulates Bhabha’s vision for India and sheds light on his rich legacy. His legendary leadership in organizing scientific research in India, his drive and passion continue to inspire generations of students in India.
