Srinivasan was born on 14 April 1941 in a small village called Asikkadu in Mayiladuthurai district in the south Indian state of Tamil Nadu. He was born into a traditional Tamil Brahmin Iyer family, and grew up performing traditional rituals. He graduated in electrical engineering (BE) with honours from Annamalai University and secured a post-graduate degree in aeronautical engineering from the Indian Institute of Science (IISc), Bangalore. He was married to the daughter of Subramanian Iyer of Arayapuram, Lakshmi and had two children. He started his career as an aeronautical engineer at Hindustan Aeronautics Limited (HAL), but took a break to move to Ohio State University for his doctoral studies from where he obtained a PhD in engineering mechanics in 1970. Returning to India the same year, he joined Indian Space Research Organization (ISRO) where he would work for the rest of his life. Srinivasan's early assignments at ISRO included the development of Rohini satellite and later, the initiation of satellite launch vehicle (SLV) from 1973 onwards. In 1980, when A. P. J. Abdul Kalam started his work on SLV-3, Srinivasan assisted him as the deputy director of the project and successfully launched the vehicle. The duo launched several SLV-3 flights in the ensuing years till he was moved to the Polar Satellite Launch Vehicle (PSLV) project, the first indigenously designed Indian Satellite Launch Vehicle. In 1988, he became the director of the Integrated Launch Vehicle Program but continued to be associated with PSLV and Geosynchronous Satellite Launch Vehicle (GSLV) programs. He headed Satish Dhawan Space Centre (SHAR), Shreeharikota, for a while before moving to Thiruvananthapuram to head the Vikram Sarabhai Space Centre (VSSC) in 1994. At VSSC, he was reported to have been involved with the configuration, design, development and execution of the PSLV project, culminating in the first successful commercial launch of the vehicle on 26 May 1999. Five months after the launch, he died in harness on 1 September 1999, at the age of 58, survived by his wife Lakshmi and two children, now settled abroad. Awards, honors and positions
