Mankombu Sambasivan Swaminathan was born in Kumbakonam district of Tamil Nadu in 7 August 1925 in a well-to-do family. He earned his Bachelor’s degree in Zoology in Maharajas College in Trivandrum, Kerala and later went on to again earn a Bachelor’s degree in Agricultural Sciences from Tamil Nadu Agricultural University. He described that his motivation for choosing his career path in agricultural sciences was the Bengal famine of 1943. He then took up a career in plant genetics mainly focussing on plants that served as source of food for humans. He is known as the “Father of Green Revolution in India” for his leadership and success in introducing high yield varieties of wheat and rice in India. He was the first recipient of World Food Prize in 1987. He has worked worldwide in collaboration with students and colleagues on a range of subjects pertaining to plant breeding, agricultural research and development and conservation of natural resources. He has been honored by Government of India with Padma Shri, Padma Bhushan and Padma Vibhushan for his contributions. He is currently the chairman of the National Commission on Agriculture, Food and Nutrition Security of India.

Under Government of India’s scholarship, he finished his master’s degree from Cambridge University. He is known for his theory of maximum mass of a stable white dwarf star, now known as “Chandrasekhar limit.” He received Nobel Prize along with William A. Fowler in 1983 for his studies on the physical processes important to the structure and evolution of stars. He received 14 famed international awards for his contributions to the field of science in his lifetime. He died of a sudden heart attack in 1995 in the University of Chicago Hospital.

Homi Jehangir Bhabha (1909-1966)

Homi Jehangir Bhabha-Indian Scientists of Modern Times

Homi Jehangir Bhabha was an Indian nuclear physicist and most famously is known as “Father of Indian Nuclear Programme.” He was born in a wealthy Parsi family and was related to the Tata family. After completing his studies overseas in Cambridge University and after WWII broke out, he returned to India and decided to stay here. After Independence, he heralded India’s dream of a nuclear future. He is credited with formulating the country’s strategy in the field of nuclear power to focus on extracting power from the country’s vast thorium reserves. As a result of Bhabha’s vision, “India has the most technically ambitious and innovative nuclear energy program in the world. The extent and functionality of its nuclear experimental facilities are matched only by those in Russia and are far ahead of what is left in the US.” He died when Air India Flight 101 crashed near Mont Blanc on January 24, 1966. One conspiracy theory is that CIA was involved with the crash possibly to cripple India’s nuclear programme.

C. V. Raman (1888-1970)

C. V. Raman-Indian Scientists of Modern Times

C.V. Raman was born in 1888 in Thiruvanaikaval, near Tiruchirappalli in the Madras Province. He was second of five children. His father was the lecturer of physics and mathematics at the Presidency College in Madras. At just the age of 13, in 1903, he entered Presidency College of Madras to pursue his interests in Physics. He finished his postgraduation in physics in the same institution. After many years of government service, he resigned to become a professor of physics in University of Calcutta in 1917. Alongside, he also worked for a number of Indian research institutions throughout his career. He is most notable for his discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon has now come to be known as Raman scattering and is the result of Raman Effect. He was the recipient of Nobel Prize for Physics in 1930 for this discovery. C.V. Raman during his career wrote as much as 63 article and papers, both for Indian and international magazines. He died on November 21, 1970.
