Nambi Narayanan Family Tree
Nambi Narayanan - A Lifestory

Nambi Narayanan is a distinguished Indian aerospace engineer who played a pivotal role in the development of India's liquid propellant rocket technology. Born in Nagercoil, Tamil Nadu, he pursued his engineering studies before embarking on a career with the Indian Space Research Organisation (ISRO) in 1966. His early work involved the development of solid rocket motors, but his true passion lay in the potential of liquid propulsion.
Narayanan's dedication led him to pursue advanced studies in chemical rocket propulsion at Princeton University in the United States. Upon his return to India, he spearheaded the effort to master liquid propulsion technology, recognizing its crucial importance for advanced launch vehicles. He introduced the Liquid Propulsion Systems Centre (LPSC) at ISRO and was instrumental in acquiring and adapting the French Vikas engine technology, a critical step in India's space program. This technology later powered the PSLV and GSLV rockets, significantly enhancing India's capabilities in launching satellites.
Beyond his technical contributions, Narayanan is also known for the controversy surrounding his alleged involvement in espionage in 1994. He was falsely accused of leaking sensitive information to foreign agents and endured significant hardship and public humiliation as a result. Despite the accusations, he maintained his innocence, and after a protracted legal battle, the Supreme Court of India exonerated him of all charges. The court also criticized the investigation and directed the state government to provide compensation for the suffering he endured.
Following his vindication, Nambi Narayanan has become a vocal advocate for justice and has dedicated himself to clearing his name and highlighting the injustices he faced. His story serves as a reminder of the importance of due process and the potential for individuals to be wrongly accused. He continues to be recognized for his contributions to Indian space technology and his unwavering pursuit of truth and justice.
