Born: 7 November 1888, Trichinopoly, India

Died: 21 November 1970, Bangalore, India

Affiliation at the time of the award:Calcutta University, Calcutta, India

Prize motivation: "for his work on the scattering of light and for the discovery of the effect named after him"

Field: Atomic physics, electromagnetism

Chandrasekhara Venkata Raman was born at Trichinopoly in Southern India on November 7th, 1888. His father was a lecturer in mathematics and physics so that from the first he was immersed in an academic atmosphere. He entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he gained his M.A. degree, obtaining the highest distinctions.

His earliest researches in optics and acoustics - the two fields of investigation to which he has dedicated his entire career - were carried out while he was a student.

Since at that time a scientific career did not appear to present the best possibilities, Raman joined the Indian Finance Department in 1907; though the duties of his office took most of his time, Raman found opportunities for carrying on experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta (of which he became Honorary Secretary in 1919).

In 1917 he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. After 15 years at Calcutta he became Professor at the Indian Institute of Science at Bangalore (1933-1948), and since 1948 he is Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he is the Editor. Raman sponsored the establishment of the Indian Academy of Sciences and has served as President since its inception. He also initiated the Proceedings of that academy, in which much of his work has been published, and is President of the Current Science Association, Bangalore, which publishes Current Science (India).

Some of Raman's early memoirs appeared as Bulletins of the Indian Associationfor the Cultivation of Science (Bull. 6 and 11, dealing with the "Maintenance of Vibrations"; Bull. 15, 1918, dealing with the theory of the musical instruments of the violin family). He contributed an article on the theory of musical instruments to the 8th Volume of the Handbuch der Physik, 1928. In 1922 he published his work on the "Molecular Diffraction of Light", the first of a series of investigations with his collaborators which ultimately led to his discovery, on the 28th of February, 1928, of the radiation effect which bears his name ("A new radiation", Indian J. Phys., 2 (1928) 387), and which gained him the 1930 Nobel Prize in Physics.

Other investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. In 1948 Raman, through studying the spectroscopic behaviour of crystals, approached in a new manner fundamental problems of crystal dynamics. His laboratory has been dealing with the structure and properties of diamond, the structure and optical behaviour of numerous iridescent substances (labradorite, pearly felspar, agate, opal, and pearls).

Among his other interests have been the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision.

Raman has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected a Fellow of the Royal Society early in his career (1924), and was knighted in 1929.

Sir Venkata Raman died on November 21, 1970.

Dirubhai Ambani

Born : December 28, 1932

Died: July 6, 2002

Achievements: Dhiru Bhai Ambani built India's largest private sector company. Created an equity cult in the Indian capital market. Reliance is the first Indian company to feature in Forbes 500 list

Dhirubhai Ambani was the most enterprising Indian entrepreneur. His life journey is reminiscent of the rags to riches story. He is remembered as the one who rewrote Indian corporate history and built a truly global corporate group.

Dhirubhai Ambani alias Dhirajlal Hirachand Ambani was born on December 28, 1932, at Chorwad, Gujarat, into a Modh family. His father was a school teacher. Dhirubhai Ambani started his entrepreneurial career by selling "bhajias" to pilgrims in Mount Girnar over the weekends.

After doing his matriculation at the age of 16, Dhirubhai moved to Aden, Yemen. He worked there as a gas-station attendant, and as a clerk in an oil company. He returned to India in 1958 with Rs 50,000 and set up a textile trading company.

Assisted by his two sons, Mukesh and Anil, Dhiru Bhai Ambani built India's largest private sector company, Reliance India Limited, from a scratch. Over time his business has diversified into a core specialisation in petrochemicals with additional interests in telecommunications, information technology, energy, power, retail, textiles, infrastructure services, capital markets, and logistics.

Dhirubhai Ambani is credited with shaping India's equity culture, attracting millions of retail investors in a market till then dominated by financial institutions. Dhirubhai revolutionised capital markets. From nothing, he generated billions of rupees in wealth for those who put their trust in his companies. His efforts helped create an 'equity cult' in the Indian capital market. With innovative instruments like the convertible debenture, Reliance quickly became a favorite of the stock market in the 1980s.

In 1992, Reliance became the first Indian company to raise money in global markets, its high credit-taking in international markets limited only by India's sovereign rating. Reliance also became the first Indian company to feature in Forbes 500 list.

Dhirubhai Ambani was named the Indian Entrepreneur of the 20th Century by the Federation of Indian Chambers of Commerce and Industry (FICCI). A poll conducted by The Times of India in 2000 voted him "greatest creator of wealth in the century".

Dhirubhai Ambani died on July 6, 2002, at Mumbai.

Quates of Dhirubhai

”Think big, think fast, think ahead , ideas are no one’s monopoly”
“Our dream have to be bigger. Our ambitions higher. Our commitments depper. And our efforts greater. This is my dream for Reliance an for India.”
Growth through Vision
“Growth has no limit at Reliance. I keep revising my vision.
