Who is C.V. Raman?

Today lets talk about Biography of C.V. Raman: How a curious boy from Tamil Nadu became India’s first Nobel Prize winner in science and changed our understanding of light forever. On a voyage across the Mediterranean Sea in 1921, a young Indian physicist stood on the deck of a ship, mesmerized by the deep blue color of the water. While most passengers simply admired the beauty, C.V. Raman asked a different question: “Why is the sea blue?” This simple question would lead to one of the most significant discoveries in physics and make him the first Asian to win a Nobel Prize in science.

C.V. Raman. A Brahmin Boy Born Into Science

Chandrasekhara Venkata Raman was born on November 7, 1888, in Tiruchirappalli (then called Trichinopoly), a historic town in Tamil Nadu, Southern India. He was born into a Tamil Brahmin family with deep roots in the Tanjore district, where his ancestors were established agriculturists near Porasakudi Village and Mangudi.

An Academic Household

Raman’s entry into the world of science was almost predestined. His father, Chandrasekhara Iyer (also written as R. Chandrasekhara Aiyer or Chandrasekaran Ramanathan Iyer), was a lecturer in mathematics and physics. His mother, Parvathi Ammal, provided a nurturing home environment. From his earliest days, young Raman was immersed in an academic atmosphere where scientific discussions were as common as dinner conversations.

The family faced financial struggles during Raman’s birth, but fortune smiled when his father secured a professor position, providing the stability needed for the family to thrive and for young Raman’s education to flourish.

A Precocious Child

Raman was a precocious child who showed exceptional intellectual abilities from a remarkably young age. His father’s profession ensured that he had early exposure to scientific concepts, and his natural curiosity found fertile ground in books about physics and mathematics that were readily available at home.

The academic environment his father created wasn’t just about having books, it was about fostering questioning, investigation, and the joy of discovery. These early influences would shape Raman’s approach to science throughout his life.

C.V. RamanEducation: Excellence from the Start

School Years

Raman completed his secondary and higher secondary education from St. Aloysius’ Anglo-Indian High School in Visakhapatnam (then Vizagapatam), Andhra Pradesh, where his family had moved when his father took up a position there. Even in school, Raman’s brilliance was evident to his teachers and peers.

Presidency College, Madras

At the remarkably young age of 13, Raman entered Presidency College, Madras (now Chennai), one of India’s premier educational institutions. This wasn’t just early admission—it was a testament to his extraordinary intellectual abilities.

In 1904, at just 16 years old, Raman passed his Bachelor of Arts (B.A.) examination, winning the first place and a gold medal in physics. But he didn’t stop there. He continued his studies and in 1907, at age 18, he obtained his Master of Arts (M.A.) degree in physics with distinction, once again securing the highest marks.

His M.A. thesis on the diffraction of light was published in the British journal “Philosophical Magazine” while he was still a student—an extraordinary achievement that foreshadowed the groundbreaking work he would do later in his career.

C.V. RamanDifficult Choice: Science or Service?

The Financial Services Interlude

Despite his brilliance and passion for science, Raman faced a harsh reality: in early 20th-century colonial India, opportunities for scientific research were virtually nonexistent. Scientific research was almost completely neglected in India during this period, with minimal funding, infrastructure, or institutional support.

Faced with the need to earn a living and support his family, Raman made a pragmatic decision. He appeared for the Financial Civil Services (FCS) examination in 1907 and secured the first position. At age 19, he joined the Indian Finance Department in Calcutta (now Kolkata) as an Assistant Accountant General.

This seemed like the end of his scientific ambitions. A stable government job with good pay was what any sensible person would choose. But Raman was not ready to abandon his first love, physics.

C.V. Raman Double Life

What happened next demonstrates Raman’s extraordinary dedication to science. While working his demanding government job during the day, he spent every available moment conducting experiments at the Indian Association for the Cultivation of Science (IACS) in Calcutta.

Founded in 1876 by Dr. Mahendra Lal Sircar, IACS was India’s first research institute. Despite having minimal equipment and resources, Raman transformed it into his personal laboratory. He would arrive early in the morning before work, return during lunch breaks, and stay late into the night, conducting experiments on acoustics and optics with whatever equipment he could cobble together.

For ten years (1907-1917), Raman led this double life, government servant by day, passionate scientist by night and weekend. The research he conducted during this period resulted in numerous papers published in international journals, earning him recognition in the global scientific community even though he held no academic position.

C.V. Raman Return to Pure Science

The Career Change

By 1917, Raman had established such a strong reputation through his part-time research that he was offered the Palit Professorship of Physics at the University of Calcutta. This position would allow him to pursue research full-time, but it came with a significant sacrifice, he would have to give up his secure, well-paying government job with pension benefits.

Many advised against this decision. Giving up financial security for the uncertain world of academic research in a country with limited scientific infrastructure seemed foolish. But Raman’s passion for science outweighed practical considerations. He resigned from government service and accepted the professorship, marking his full commitment to scientific research.

C.V. Raman Building Indian Science

At Calcutta University, Raman began building what would become one of India’s most productive research schools. He gathered talented students around him, creating an atmosphere of scientific inquiry and discovery. Despite limited resources compared to Western laboratories, Raman’s group began producing high-quality research that gained international attention.

He continued his association with IACS, where he conducted much of his experimental work. The combination of teaching at the university and researching at IACS allowed him to mentor the next generation of Indian scientists while pushing the boundaries of knowledge himself.

C.V. Raman Mediterranean Mystery and the Birth of a Discovery

The Blue Water Question

In 1921, Raman was invited to the Universities Congress of the British Empire in Oxford. The sea voyage to Europe provided him with an experience that would change the course of his research. Standing on the deck, observing the stunning blue color of the Mediterranean Sea, Raman was dissatisfied with the prevailing explanation.

The standard scientific explanation at the time, proposed by Lord Rayleigh, was that the sea appeared blue simply because it reflected the color of the sky. But Raman’s trained eye and scientific intuition told him this couldn’t be the complete answer. The blue he observed was too deep, too intense to be merely a reflection.

Using simple equipment, a Nicol prism and a pocket spectroscope, right there on the ship’s deck, Raman conducted preliminary observations that convinced him something else was happening. The sea had its own blue color, independent of the sky. But what caused it?

The Quest for Understanding

This observation became an obsession. After returning to India, Raman began intensive experiments on the scattering of light. He knew that when light passes through a transparent material, most of it passes straight through, some is absorbed, and some is scattered in different directions. But the details of this scattering held secrets.

The Raman Effect: A Revolution in Physics

February 28, 1928: A Day to Remember

On February 28, 1928, after years of meticulous experimentation with his collaborator K.S. Krishnan, Raman made a discovery that would revolutionize physics. They found that when light traverses a transparent material—whether solid, liquid, or gas—some of the deflected light changes wavelength.

This was extraordinary. It meant that light wasn’t just bouncing off molecules unchanged; it was interacting with them in a fundamental way. When a photon (light particle) hits a molecule, it can transfer some of its energy to the molecule or receive energy from it, resulting in scattered light with a different wavelength than the original light.

Understanding the Discovery

To appreciate the significance, imagine throwing a ball at a wall. Normally, the ball bounces back with roughly the same energy (ignoring friction). But what Raman discovered was equivalent to the ball sometimes bouncing back with more or less energy than it started with, having exchanged energy with the wall itself.

This phenomenon, now called the Raman effect or Raman scattering, provided a powerful new tool for understanding molecular structure. Because the wavelength change depends on the molecular structure of the material, scientists could use Raman scattering to identify unknown substances and study molecular properties.

C.V. Raman Immediate Recognition

Raman immediately recognized the importance of his discovery. In a bold move, he sent a brief report to Nature magazine, which was published on March 31, 1928, under the title “A New Radiation.” He followed this with more detailed papers explaining the phenomenon.

The scientific community was electrified. Here was a completely new physical phenomenon with profound implications for molecular physics and chemistry. The discovery was so significant and well-established that within just two years, Raman would receive science’s highest honor.

C.V. Raman Nobel Prize and International Acclaim

1930: India’s First Science Nobel

On December 10, 1930, in Stockholm, Sweden, Chandrasekhara Venkata Raman received the Nobel Prize in Physics “for his work on the scattering of light and for the discovery of the effect named after him.” At age 42, he had achieved what no other Asian or non-White person had achieved before, winning a Nobel Prize in any branch of science.

Raman was the first Asian and the first non-White recipient of a Nobel Prize in science, a groundbreaking achievement that inspired generations of scientists across Asia and the developing world. The award put Indian science on the world map and proved that scientific excellence could emerge from anywhere, not just well-funded Western laboratories.

Knighthood and Other Honors

The same year, the British government knighted him, and he became Sir C.V. Raman. But this was just one of many honors that would come his way:

1. 1924: Fellow of the Royal Society (FRS), one of the highest honors in science
2. 1930: Hughes Medal from the Royal Society
3. 1930: Nobel Prize in Physics
4. 1941: Franklin Medal
5. 1954: Bharat Ratna, India’s highest civilian award
6. 1957: Lenin Peace Prize

He received honorary doctoral degrees from numerous universities worldwide and was elected to scientific academies across the globe.

C.V. Raman Building Indian Scientific Institutions

Indian Institute of Science, Bangalore

In 1933, three years after winning the Nobel Prize, Raman left Calcutta for Bangalore to serve as the head of the Indian Institute of Science (IISc). This was then India’s premier research institution, and Raman saw an opportunity to shape Indian science at the institutional level.

During his tenure at IISc, he continued his research on the structure of crystals and minerals, the properties of diamonds, and the physics of musical instruments. He established research schools in various areas of physics and mentored numerous students who would go on to become leading scientists themselves.

Raman Research Institute

Raman’s vision extended beyond existing institutions. In 1948, he founded the Raman Research Institute (RRI) in Bangalore, a private research institute dedicated to fundamental research in physics. Even after retiring from IISc, he continued active research at RRI, which remains today a prestigious center for physics research.

The establishment of RRI demonstrated Raman’s commitment to creating sustainable scientific infrastructure in India. He used his personal resources and raised funds to build an institution that would outlast him and continue contributing to science.

C.V. Raman Scientific Contributions Beyond the Raman Effect

While the Raman effect remains his most famous discovery, C.V. Raman made significant contributions to many areas of physics:

Acoustics and Musical Instruments

Raman had a lifelong fascination with music and musical instruments. He conducted extensive research on the physics of musical instruments, particularly Indian instruments like the violin, tambura, tabla, and mridangam. His papers on acoustics helped explain why these instruments produce their characteristic sounds.

His work in acoustics wasn’t just theoretical—he had a deep appreciation for music itself. He often said that his interest in the violin and other musical instruments was what first drew him to the study of vibrations and waves.

Crystal Physics

After discovering the Raman effect, Raman became interested in the structure and properties of crystals and minerals. He studied how light behaves when passing through crystals, leading to important insights about crystal structure and symmetry.

Optics and Vision

Raman contributed to understanding various optical phenomena, including the color of flowers, the opalescence of solutions, and aspects of human vision. His approach was always to question conventional explanations and seek deeper understanding.

The Blue of the Ocean and Sky

Raman never forgot the question that sparked his research journey. He continued studying why the ocean and sky appear blue, eventually providing a more complete explanation than had existed before, relating it to molecular scattering of light.

C.V. Raman Personal Life and Character

Family

In 1907, the same year he completed his M.A. and joined the Financial Civil Service, Raman married Lokasundari Ammal. The marriage was arranged, as was customary in Indian society at that time. Lokasundari proved to be a supportive partner throughout Raman’s demanding career, managing the household and supporting his single-minded dedication to science.

The couple had two sons:

• C.V. Radhakrishnan, who became a distinguished astrophysicist
• C.V. Chandrasekhar, who pursued a career in business

His nephew, Subrahmanyan Chandrasekhar, would follow in his uncle’s footsteps to win the Nobel Prize in Physics in 1983, making them one of the few uncle-nephew pairs of Nobel laureates.

C.V. Raman Personality and Work Ethic

Those who knew Raman described him as a man of intense focus and dedication. When engaged in a research problem, he would work tirelessly, often forgetting meals and sleep. His passion for science was infectious, inspiring students and colleagues.

However, Raman could also be demanding and difficult. He had high standards and expected the same level of dedication from others that he demonstrated himself. Some found him difficult to work with, while others were inspired by his intensity and commitment.

He was known for his simple lifestyle despite his fame and honors. He lived modestly, directing his energies and resources toward research rather than personal luxury.
