He ended his career as professor emeritus of the Raman Research Institute named after his father in Bangalore, India, of which he had earlier been director from 1972 to 1994.

Venkatraman served on various councils in various capacities including as the vice president of the International Astronomical Union between the year 1988 to 1994.

Radhakrishnan is particularly credited for various works in finding Deuterium abundance in the galaxy, Astrophysical Raman Masers, OH emission from clouds, etc. [Reference]

5. Satyendra Nath Bose

Satyendra Nath Bose was an Indian physicist and mathematician who is best known for his work on quantum mechanics in the early 1920s.

Bose developed a new method of counting particles that was later named after him: the Bose-Einstein statistics.

In 1924, he sent a paper to Albert Einstein entitled “Planck’s Law and the Hypothesis of Light Quanta” which proposed the existence of particles that we now know as photons.

Einstein was so impressed with the paper that he published it without changes in the prestigious German scientific journal Zeitschrift für Physik. [Reference]

6. Har Gobind Khorana

Har Gobind Khurana was an Indian-American biochemist who shared the 1968 Nobel Prize for Physiology or Medicine with Marshall W. Nirenberg and Robert W. Holley for research that showed that the order of nucleotides in nucleic acids, which carry the genetic code of the cells, control the cell’s synthesis of proteins.

Khurana was born in Raipur, India, and earned a B.Sc. from Punjab University in Lahore, Pakistan, in 1945. He then moved to the United States, where he received a Ph.D. in organic chemistry from the University of Illinois in 1949. [Reference]

7. Homi Jahangir Bhabha

Homi Jahangir Bhabha was an Indian nuclear physicist who is often referred to as the “father of the Indian nuclear program”.
