Early life and education
Rao was born in a poor peasant’s family to Venkatachalam and Sundaramma on September 20, 1914 at Mogallu village of the fertile and picturesque West Godavari district of Andhra Pradesh. After schooling in his native state, he moved to Banaras Hindu University where he took his Master of Science degree in Physics in 1939, with high academic honours. For the next six years he taught and conducted research in that University. In 1946, Rao was selected for the prestigious Tata scholarship on which he went to Stanford University to take his Master's degree in Electrical Engineering. On his return from the US, Rao joined Tata Institute of Fundamental Research as a Reader in Experimental Physics and thus began his association with Dr Homi J. Bhabha in the development of India's science and technology. In the early days of his career, Rao worked on high altitude cosmic ray research. Very soon he localised his area of specialist interest in Electronic Instrumentation and it was possible for Bhabha to leave this dimension of developmental effort in the capable hands of Rao. He was the director of radiation health protection and electronics groups at Bhabha Atomic Research Centre (Barc) and later played a key role in setting up ECIL in the city of Hyderabad in 1967 when the Dept of Atomic Energy (DAE) decided to go commercial in its electronics research.
