Sir Granville Beynon is a towering figure on the world stage of scienc
e and engineering. He has personally assisted developing countries, of
which India was a particularly fortunate one, to train their young wo
rkers in the methods of research and to introduce new experimental tec
hniques. Special mention is made here of his support for radio science
in India and for his influential contributions to URSI, to the IGY (A
GI in French), the IQSY and the MAP.
