Dr. Chandrasekhara Venkata Raman (CV Raman): Childhood and family life
Dr. CV Raman was born on 7 November 1888 in a South Indian Brahmin family in Tiruchirappalli, Tamil Nadu. His father’s name was Chandrasekhara Ramanathan Iyer, a lecturer in Mathematics and Physics at a college in Vishakhapatnam. His mother’s name is Parvathi Ammal.
CV Raman was an intelligent and excellent student from an early age. At the age of 11, he passed the entrance exam and entered 12th grade at the age of 13 thanks to a scholarship. In 1902, he joined the Presidency College and received his diploma in 1904. At that time, he was the only student to receive a first class award. He did his Master’s degree in Physics from the same university and broke all previous records. In 1907, he married Lokasundari Ammal and had two sons, Chandrasekhar and Radhakrishnan.

Dr. Chandrasekhara Venkata Raman (CV Raman): Career
Because of his father’s interest, he appeared for the Financial Civil Services (FCS) exam and topped. In 1907, he went to Calcutta (now Kolkata) and worked as Assistant Accountant General. But in his spare time, he goes to the lab to do research at the Indian Society of Scientific Horticulture. Let us tell you, his work is very busy and he also continues his research work at night because of his core interest in science.
Although the facilities available in the laboratory were very limited, he continued his research and published his findings in leading international journals including ‘Nature’, ‘Journal of Philosophy’ ‘, ‘Journal of Physics’, etc. At that time, his research focused on the fields of vibration and acoustics.
He got the opportunity to join Calcutta University in 1917, as the first Palit Professor of Physics. After 15 years in Calcutta, he became a Professor at the Indian Institute of Science at Bangalore from 1933-1948 and from 1948 he became Director of the Raman Research Institute at Bangalore, which he founded and funded.
Dr. Chandrasekhara Venkata Raman (CV Raman): Works and discoveries
He founded the Indian Physical Review in 1926 and was its Editor. He also sponsored the establishment of the Indian Academy of Sciences and served as its President since its inception. He is the President of the Current Science Association in Bangalore, which publishes Current Science (India).
In 1928 he wrote an article on musical instrument theory for Volume 8 of Handbuch der Physik. He published his work on “Molecular Diffraction of Light” in 1922, which led to his final discovery of radiation effects on February 28, 1928, and earned him the Nobel Prize in Physics in 1928. 1930. He became the first Indian to receive the Nobel Prize.
Other research carried out by Dr. CV Raman are: Diffraction of light by acoustic waves of ultrasonic and ultrasonic frequencies as well as X-ray-induced effects on infrared vibrations in exposed crystals with normal light.
In 1948, he also studied the fundamentals of crystal dynamics. His laboratory is researching the structure and properties of diamonds as well as the structure and optical properties of many iridescent substances such as pearls, agates, opals, etc.
He is also interested in the optics of colloids, electric and magnetic anisotropy, and the physiology of human vision.
Undoubtedly, he was honored with many doctorates and memberships in scientific associations. In 1924 he was also elected a Fellow of the Royal Society early in his career and was knighted in 1929.
As briefly described, he is best known for his discovery of the ‘Raman Effect’ or the theory related to the scattering of light. He showed that when light passes through a transparent material, some of the deflected light changes its wavelength.
