JRD Tata

JRD Tata was one of the most enterprising Indian entrepreneurs. He was a pioneer aviator and built one of the largest industrial houses of India. JRD Tata was born on July 29, 1904 in Paris. His mother was a French, while his father was Parsi. JRD's full name was Jehangir Ratanji Dadabhoy Tata and he was popularly known as Jeh to his friends. JRD's father Ratanji Dadabhoy Tata and Sri Jamsetji Tata shared their greatness from the same great-great-grandfather, Ervad Jamsheed Tata, a priest of Navsari.

JRD Tata was the second of four children. He was educated in France, Japan and England before being drafted into the French army for a mandatory one-year period. JRD wanted to extend his service in the forces but destiny had something else in store for him. By leaving the French army JRD's life was saved because shortly thereafter, the regiment in which he served was totally wiped out during an expedition in Morocco. JRD Tata joined Tata & Sons as an unpaid apprentice in 1925. He has great interest in flying. On February 10, 1929, JRD became the first Indian to pass the pilot's examination. With this distinctive honor of being India's first pilot, he was instrumental in giving wings to India by building Tata Airlines, which ultimately became Air India. His passion for flying was fulfilled with the formation of the Tata Aviation Service in 1932.

JRD was the trustee of Sir Dorabji Tata Trust from its inception in 1932, which remained under his wings for over half a century. Under his guidance, this Trust established Asia's first cancer hospital, the Tata Memorial Center for Cancer, Research and Treatment, Bombay, 1941. It also founded the Tata Institute of Social Sciences, 1936 (TISS), the Tata Institute of Fundamental Research, 1945 (TIFR), and the National Center for Performing Arts. In 1948, JRD Tata launched Air India International as India's first international airline. In 1953, the Indian Government appointed JRD as Chairman of Air-India and a director on the Board of Indian Airlines-a position JRD retained for 25-years. For his crowning achievements in Aviation, JRD was bestowed with the title of Honorary Air Commodore of India.

Dhirubhai Ambani - Indian Entrepreneur

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 completing 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.

Dr Shanti Swaroop Bhatnagar

Dr Shanti Swaroop Bhatnagar was a distinguished Indian scientist. He was born on 21 February 1894 at Shahpur, which is located in Pakistan in present times. His father passed away sometime after the birth of Shanti Swarup Bhatnagar. As such, he spent his childhood days with his maternal grandfather who was an engineer and it was here that he developed an interest in science and engineering. Read on this biography to know more about the life and professional history of Dr Shanti Swaroop Bhatnagar.

As a child, Bhatnagar loved to construct mechanical toys. In the home of his maternal family, he also developed an interest in writing poetry and his one act play in Urdu 'Karamati' won the first prize in a competition. After completing his master's in India, Shanti Swaroop Bhatnagar headed to England for a research fellowship. Here he got his D. Sc degree from the London University in the year 1921. When he came back to his native country, Bhatnagar was presented with a proposal of professorship at the renowned Benaras Hindu University. Dr Bhatnagar was knighted by the British Government in the year 1941 as an award for his research in science, whereas, on 18 March 1943 he was selected as fellow of the Royal Society. Though his area of interest included emulsions, colloids, and industrial chemistry, but his primary contributions were in the spheres of magneto-chemistry. He also made a melodious kulgeet i.e. University song, which is still sung with great pride before any function in his university.

Srinivasa Ramanujan - Great Mathematician

Srinivasa Ramanujan was a mathematician par excellence. He is widely believed to be the greatest mathematician of the 20th Century. Srinivasa Ramanujan made significant contribution to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series. Srinivasa Aiyangar Ramanujan was born on December 22, 1887 in Erode, Tamil Nadu. His father worked in Kumbakonam as a clerk in a cloth merchant's shop. At the of five Ramanujan went to primary school in Kumbakonam. In 1898 at age 10, he entered the Town High School in Kumbakonam. At the age of eleven he was lent books on advanced trigonometry written by S. L. Loney by two lodgers at his home who studied at the Government college. He mastered them by the age of thirteen. Ramanujan was a bright student, winning academic prizes in high school.

At age of 16 his life took a decisive turn after he obtained a book titled" A Synopsis of Elementary Results in Pure and Applied Mathematics". The book was simply a compilation of thousands of mathematical results, most set down with little or no indication of proof. The book generated Ramanujan's interest in mathematics and he worked through the book's results and beyond. By 1904 Ramanujan had begun to undertake deep research. He investigated the series (1/n) and calculated Euler's constant to 15 decimal places. He began to study the Bernoulli numbers, although this was entirely his own independent discovery. He was given a scholarship to the Government College in Kumbakonam which he entered in 1904. But he neglected his other subjects at the cost of mathematics and failed in college examination. He dropped out of the college. Ramanujan lived off the charity of friends, filling notebooks with mathematical discoveries and seeking patrons to support his work. In 1906 Ramanujan went to Madras where he entered Pachaiyappa's College. His aim was to pass the First Arts examination which would allow him to be admitted to the University of Madras. Continuing his mathematical work Ramanujan studied continued fractions and divergent series in 1908. At this stage he became seriously ill again and underwent an operation in April 1909 after which he took him some considerable time to recover.

On 14 July 1909 Ramanujan marry a ten year old girl S Janaki Ammal. During this period Ramanujan had his first paper published, a 17-page work on Bernoulli numbers that appeared in 1911 in the Journal of the Indian Mathematical Society. In 191,1 Ramanujan approached the founder of the Indian Mathematical Society for advice on a job. He got the job of clerk at the Madras Port Trust with the help of Indian mathematician Ramachandra Rao. The professor of civil engineering at the Madras Engineering College C L T Griffith was interested in Ramanujan's abilities and, having been educated at University College London, knew the professor of mathematics there, namely M J M Hill. He wrote to Hill on 12 November 1912 sending some of Ramanujan's work and a copy of his 1911 paper on Bernoulli numbers. Hill replied in a fairly encouraging way but showed that he had failed to understand Ramanujan's results on divergent series.

 In January 1913 Ramanujan wrote to G H Hardy having seen a copy of his 1910 book Orders of infinity. Hardy, together with Littlewood, studied the long list of unproved theorems which Ramanujan enclosed with his letter. Hardy wrote back to Ramanujan and evinced interest in his work. University of Madras gave Ramanujan a scholarship in May 1913 for two years and, in 1914, Hardy brought Ramanujan to Trinity College, Cambridge, to begin an extraordinary collaboration. Right from the start Ramanujan's collaboration with Hardy led to important results. In a joint paper with Hardy, Ramanujan gave an asymptotic formula for p(n). It had the remarkable property that it appeared to give the correct value of p(n), and this was later proved by Rademacher.

Birbal Sahni

Birbal Sahni was a renowned paleobotanist of India, who studied the fossils of the Indian subcontinent. Also a great geologist, Sahni is credited for establishing the Birbal Sahni Institute of Palaeobotany at Lucknow in the state of Uttar Pradesh. Born on 14 November in the year 1891 at Behra in the Saharanpur District of West Punjab, Birbal was the third son of Ishwar Devi and Prof. Ruchi Ram Sahni. Some famous personalities who were regular guests of his parents were Motilal Nehru, Gopal Krishna Gokhale, Sarojini Naidu and others.

He completed education at the Government College University of Lahore and later from Punjab University. He attended the Emmanuel College at Cambridge in the year 1914. And after this, he pursued further studies under Professor A.C. Seward and was given the D.Sc. degree from London University in the year 1919. Birbal Sahni then came back to his native country India to work as the professor of Botany at the highly esteemed Banaras Hindu University at the holy city of Varanasi. Sahni also taught at the Punjab University for about a year. Birbal Sahni's academic background was so strong that he was elected the head of the botany department in Lucknow University in the year 1921. There were numerous such landmarks in the life history of Birbal Sahni, whose fabulous research work was honored by the University of Cambridge that decided to present him with the degree of Sc. D. in the year 1929. In the coming time, Sahni not only continued his own study, but also appointed and guided a number of bright students under him.

A. P. J. Abdul Kalam - A Scientist

Avul Pakir Jainulabdeen  A. P. J. Abdul Kalam was a scientist and engineer, who served as the President of India from 2002 to 2007. Already a highly accomplished and much respected individual when elected to be the president, Kalam had spent four decades as a scientist and science administrator at several prestigious organizations like the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO). Born into a family of humble means in Tamil Nadu, Kalam went on to study aerospace engineering in Madras Institute of Technology. His initial dream was to become a fighter pilot but he failed to qualify for the Indian Air Force. 

He then started working at the Defence Research and Development Organisation (DRDO) as a scientist and was later transferred to the Indian Space Research Organisation (ISRO). Eventually he was appointed as the Chief Scientific Adviser to the Prime Minister and in this position he played a key role in the Pokharan II nuclear tests. He became the President of India in 2002 and was known as the People's President. He left the office after serving one term and became professor of Aerospace Engineering at Anna University and a visiting professor at several other institutions.Abdul Kalam was born as the youngest of five children of a Muslim boat owner named Jainulabudeen and his wife Ashiamma, in Rameswaram, Tamil Nadu. His ancestors had once been wealthy traders though his family lost much of its fortunes by the early 20th century. Kalam grew up in humble surroundings and had to take up a job while he was still in school in order to augment his family s meager income he distributed newspapers to help his father in providing for the family. He was a bright young boy, blessed with a thirst for knowledge and was always eager to learn new things. He completed his schooling from Ramanathapuram Schwartz Matriculation School and proceeded to study physics at the Saint Joseph's College, Tiruchirappalli, from where he graduated in 1954. Then he studied aerospace engineering in Madras Institute of Technology, graduating in 1960. His childhood ambition was to become a fighter pilot but he narrowly missed achieving his dream.

Vikram Sarabhai - Space Scientist

Vikram Sarabhai was one of the greatest scientists of India. He is considered as the Father of the Indian space program. Apart from being a scientist, he was a rare combination of an innovator, industrialist and visionary. Vikram Ambalal Sarabhai was born on August 12, 1919 at Ahmedabad in an affluent family of progressive industrialists. He was one of eight children of Ambalal and Sarla Devi. He had his early education in a private school, “Retreat” run by his parents on Montessori lines. Some of the great men of India such as Gurudev Rabindranath, J. Krishna Murthi, Motilal Nehru, V. S. Shrinivasa Shastri, Jawaharlal Nehru, Sarojini Naidu, Maulana Azad, C. F. Andrews, C. V. Raman et al. used to stay with the Sarabhai family when they visited Ahmedabad. Mahatma Gandhi also once stayed at their house while recovering from an illness. Visits by such great men greatly influenced Vikram Sarabhai.

Vikram Sarabhai was instrumental in establishing the Physical Research Laboratory (PRL) in Ahmedabad in November 1947. The laboratory was established in a few rooms in M.G. Science Institute of the Ahmedabad Education Society, which was founded by his parents. Subsequently, it got support from the Council of Scientific and Industrial Research (CSIR) and the Department of Atomic Energy. Vikram Sarabhai did research on the time variations of cosmic rays and concluded that meteorological effects could not entirely affect the observed daily variations of cosmic rays; further, the residual variations were wide and global and these were related to variations in solar activity. Vikram Sarabhai visualized a new field of research opening up in solar and interplanetary Physics. The year 1957-1958 was designated as International Geo-physical year (IGY). The Indian program for the IGY had been one of the most significant ventures of Sarabhai. It exposed him to the new vistas of space science with the launching in 1957 of Sputnik-I. Subsequently, the Indian National Committee for Space Research was created, of which Vikram Sarabhai became Chairman.

After the sudden death of Homi Bhabha in an air crash, Vikram Sarabhai was appointed Chairman, Atomic Energy Commission in May 1966. He wanted the practical application of science to reach the common man. He decided to acquire competence in advance technology for the solution of country’s problems based on technical and economic evaluation of its real resources. He initiated India’s space programme, which today is renowned all over the world. Dr. Vikram Sarabhai was awarded with Shanti Swarup Bhatnagar Medal in 1962 and Padma Bhushan in 1966. Vikram Sarabhai passed away in his sleep on December 31,1971.
