Mokshagundam Visvesvarayya

Sir Mokshagundam Visvesvaraya, KCIE (Kannada: ಮೋಕ್ಷಗುಂಡಂ ವಿಶ್ವೇಶ್ವರಯ್ಯ) (other spellings include Visvesvaraya, Visweswaraiah, Vishweshwaraiah, however, "Visvesvaraya" also known as Sir MV; 15 September 1860 – 14 April 1962) was a notable Indian engineer, scholar, statesman and the Diwan of Mysore during 1912 to 1919. He was a recipient of the Indian Republic's highest honour, the Bharat Ratna, in 1955. He was knighted as a Commander of the Indian Empire by King George V for his myriad contributions to the public good. Every year, 15 September is celebrated as Engineer's Day in India in his memory. He is held in high regard as the first and pre-eminent engineer of India. He was the chief designer of the flood protection system for the city of Hyderabad.
Visvesvaraya was born to Srinivasa Shastry and Venkata lakshmamma at Muddenahalli village, Kanivenarayanapura hobli, Chikkaballapur District of present-day Karnataka, in what was then the princely state of Mysore. Srinivasa Sastry was a Sanskrit scholar and an authority on the Hindu scriptures, besides being an Ayurvedic practitioner. His mother was venkata lakshmamma.The family was a pious Telugu-speaking smartha brahmin family of mulkunadu subsect. Visvesvaraya lost his father at the age of 15.[1] He attended primary school at Chikkaballapur and high school at Bangalore.He studied his B.A. at Central College, Bangalore, affiliated to Madras University in 1881 and later studied Civil Engineering at the College of Science, Pune, now known as the College of Engineering, Pune (COEP).

Career as Engineer

Upon graduating as an engineer, Visvesvaraya took up a job with the Public Works Department (PWD) of Bombay (now known as Mumbai) and was later invited to join the Indian Irrigation Commission. He implemented an extremely intricate system of irrigation in the Deccan area. He also designed and patented a system of automatic weir water floodgates that were first installed in 1903 at the Khadakvasla Reservoir near Pune. These gates were employed to raise the flood supply level of storage in the reservoir to the highest level likely to be attained by a flood without causing any damage to the dam. Based on the success of these gates, the same system was installed at the Tigra Dam in Gwalior and the Krishnaraja Sagara (KRS) Dam in Mandya/ Mysore,Karnataka. In 1906-07, Government of India sent him to Eden,(Africa) to study water supply and drainage system and the project prepared by him was implemented in Eden successfully.
Visvesvaraya achieved celebrity status when he designed a flood protection system for the city of Hyderabad. He was instrumental in developing a system to protect Vishakapatnam port from sea erosion. [2]
Visvesvaraya supervised the construction of the KRS Dam across the Cauvery River from concept to inauguration. This dam created the biggest reservoir in Asia when it was built.[3] He was rightly called the "Father of modern Mysore state" (now Karnataka): During his period of service with the Government of Mysore state, he was responsible for the founding of, (under the Patronage of Mysore Government), the Mysore Soap Factory, the Parasitoide Laboratory, the Mysore Iron & Steel Works (now known as Visvesvaraya Iron and Steel Limited) in Bhadravathi, the Sri Jayachamarajendra Polytechnic Institute, the Bangalore Agricultural University, the State Bank of Mysore, The Century Club, Mysore Chambers of Commerce and numerous other industrial ventures. He encouraged private investment in industry during his tenure as Diwan of Mysore. He was instrumental in charting out the plan for road construction between Tirumala and Tirupati. He was known for sincerity, time management and dedication to a cause.



Diwan of Mysore

After opting for voluntary retirement in 1908, he took a foreign tour to study industrialised nations and after, for a short period he worked for Nizam of Hyderabad. He suggested flood relief measures for Hyderabad town, which was under constant threat of floods by Moosi river. Later, during November 1909, Visvesvaraya was appointed as Chief Engineer of Mysore State. Further, during the year, 1912, he was appointed as Diwan (First Minister) of the princely state of Mysore. He was Diwan for 7 years.
With the support of Krishnaraja Wodeyar IV, Maharaja of Mysore, Visvesvaraya made an arguably unprecedented contribution as Diwan to the all-round development of the state. Not only the achievements listed above, but many other industries and public works owe their inception or active nurturing to him. He was instrumental in the founding of the Government Engineering College at Bangalore in 1917, one of the first engineering institutes in India. This institution was later named the University Visvesvaraya College of Engineering after its founder. It remains one of the most reputed institutes of engineering in Karnataka. He also commissioned several new railway lines in Mysore states. Visvesvaraya was Sir Mirza Ismail's mentor and in 1926 by way of recommendation to the King who supplemented Mirza Ismail by elevating him to the coveted position of the Diwan of Mysore.



Awards and Honours

In 1915, while he was the Diwan of Mysore, Visvesvaraya was made Knight Commander of the Order of the Indian Empire by the British for his myriad contributions to the public good. After India attained independence, Sir M. Visvesvaraya was given the nation's highest honour, the Bharat Ratna, in 1955.[4]
Sir M.V. was honoured with honorary membership of the international Institution of Civil Engineers (based in London) and a fellowship of the Indian Institute of Science (based in Bangalore). He was awarded several honorary doctoral degrees like D.Sc., LL.D., D.Litt. from eight universities in India. He was president of the 1923 Session of the Indian Science Congress. Sir M.V. was awarded honorary Membership of London Institution of Civil Engineers for an unbroken 50 years.[5]

C. V. Raman

Sir Chandrasekhara Venkata Raman, FRS (Tamil: சந்திரசேகர வெங்கடராமன்) (7 November 1888 – 21 November 1970) was an Indian physicist whose work was influential in the growth of science in the world. He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect.

Venkata Raman was born at Thiruvanaikaval, near Tiruchirappalli, Madras Presidency to R. Chandrasekhara Iyer (b. 1866) and Parvati Ammal (Saptarshi Parvati).[1] He was the second of their eight children. At an early age, Raman moved to the city of Vizag, Andhra Pradesh. Studied in St.Aloysius Anglo-Indian High School. His father was a lecturer in Mathematics and physics.
Raman entered Presidency College, Chennai in 1902. In 1904, he gained his B.Sc., winning the first place and the gold medal in physics. In 1907, he gained his M.Sc., obtaining the highest distinctions. He joined the Indian Finance Department as an Assistant Accountant General.

Career

In 1917, Raman resigned from his government service and took up the newly created Palit Professorship in Physics at the University of Calcutta. At the same time, he continued doing research at the Indian Association for the Cultivation of Science, Calcutta, where he became the Honorary Secretary. Raman used to refer to this period as the golden era of his career. Many students gathered around him at the IACS and the University of Calcutta.

Personal life

Raman retired from the Indian Institute of Science in 1948 and established the Raman Research Institute in Bangalore, Karnataka a year later. He served as its director and remained active there until his death in 1970, in Bangalore, at the age of 82.
He was married on 6 May 1907 to Lokasundari Ammal with whom he had two sons, Chandrasekhar and Radhakrishnan.
C.V. Raman was the paternal uncle of Subrahmanyan Chandrasekhar, who later won the Nobel Prize in Physics (1983) for his discovery of the Chandrasekhar limit in 1931 and for his subsequent work on the nuclear reactions necessary for stellar evolution.


Honours and awards

Raman was 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 knighted in 1929. In 1930 he won the Nobel Prize in Physics. In 1941 he was awarded the Franklin Medal. In 1954 he was awarded the Bharat Ratna.[2] He was also awarded the Lenin Peace Prize in 1957.
India celebrates National Science Day on 28 February of every year to commemorate the discovery of the Raman effect in 1928.
