Early career (1949-59) Ramanna had met
Homi J. Bhabha in 1944 and was inspired by his work. In 1957, Ramanna established a training school at BARC to facilitate training of scientists in
nuclear physics. When
Indira Gandhi became the prime minister in 1966, the project for the design and manufacturing of the nuclear device proceeded secretly. The program employed 75 scientists with Ramanna heading the project and
P. K. Iyengar serving as his deputy. Later, the weapons programme was directed towards the production of
plutonium rather than
uranium and in 1969, enough plutonium had been accumulated for the production of a single nuclear bomb.
First nuclear test (1970-75) In July 1970, physicist
B. D. Nagchaudhuri was appointed as the scientific adviser to the
Defense Minister and as Director of the
Defence Research and Development Organisation (DRDO). Nagchaudhuri and Ramanna worked together to recruit the team and set up the requirements necessary for a
nuclear weapon test. In 1971,
Homi Sethna succeeded
Vikram Sarabhai as the chairman of the Atomic Energy Commission, completing the leadership group. The nuclear test was planned for May 1974 with tight control being maintained on all aspects of the preparations of the test, which was conducted in extreme secrecy. The test was code named
Smiling Buddha and called as a
Peaceful Nuclear Explosive (PNE). A
nuclear fission device was successfully detonated on 18 May 1974 at 8.05
IST. In 1975, Ramanna was honored with the
Padma Vibhushan, India's second highest civilian award.
Intermediate years (1975-87) Ramanna served as Vice President of the
Indian Academy of Sciences from 1977 to 1979 and as President of
Indian National Science Academy in
New Delhi from 1977 to 1978. In the same year, then
President of Iraq Saddam Hussein approached Ramanna for help in building a nuclear bomb when Ramanna visited
Baghdad. Ramanna refused and returned to India. In 1984, he was made the chairman of Atomic Energy Commission, which he held for three years. Later, he served as the chairman of the Scientific Advisory Committee to the Director General of IAEA and as president of the 30th General Conference in 1986. He held various academic positions including the chairman of board of Governors at
IIT Bombay, chairman of the governing council at
Indian Institute of Science and founder director of
National Institute of Advanced Studies,
Bangalore. He was a nominated member of the
Rajya Sabha, the upper house of the
Indian Parliament from 1997 to 2003. ==Death==
