Jagdish Chandra Bose Biography

Jagdish Chandra Bose Biography

Born:  November 30, 1858

Died:  November 23, 1937

Achievements:  He was the first to prove that plants too have feelings. He invented wireless telegraphy a year before Marconi patented his invention.



Jagdish Chandra Bose was an eminent Indian scientist. He was the first to prove that plants and metals too have feelings.



Jagdish Chandra Bose was born on November 30, 1858 in Mymensingh (now in Bangladesh). His father Bhagabanchandra Bose was a Deputy Magistrate. Jagadish Chandra Bose had his early education in village school in Bengal medium. In 1869, Jagadish Chandra Bose was sent to Calcutta to learn English and was educated at St.Xavier's School and College. He was a brilliant student. He passed the B.A. in physical sciences in 1879.



In 1880, Jagdishchandra Bose went to England. He studied medicine at London University, England, for a year but gave it up because of his own ill health. Within a year he moved to Cambridge to take up a scholarship to study Natural Science at Christ's College Cambridge. In 1885, he returned from abroad with a B.Sc. degree and Natural Science Tripos (a special course of study at Cambridge).



After his return Jagadish Chandra Bose, was offered lectureship at Presidency College, Calcutta on a salary half that of his English colleagues. He accepted the job but refused to draw his salary in protest. After three years the college ultimately conceded his demand and Jagdish Chandra Bose was paid full salary from the date he joined the college. As a teacher Jagdish Chandra Bose was very popular and engaged the interest of his students by making extensive use of scientific demonstrations. Many of his students at the Presidency College were destined to become famous in their own right. These included Satyendra Nath Bose and Meghnad Saha.



In 1894, Jagadish Chandra Bose decided to devote himself to pure research. He converted a small enclosure adjoining a bathroom in the Presidency College into a laboratory. He carried out experiments involving refraction, diffraction and polarization. It would not be wrong to call him as the inventor of wireless telegraphy. In 1895, a year before Guglielmo Marconi patented this invention, he had demonstrated its functioning in public.



Jagdish Chandra Bose later switched from physics to the study of metals and then plants. He fabricated a highly sensitive "coherer", the device that detects radio waves. He found that the sensitivity of the coherer decreased when it was used continuously for a long period and it regained its sensitivity when he gave the device some rest. He thus concluded that metals have feelings and memory.



Jagdish Chandra Bose showed experimentally plants too have life. He invented an instrument to record the pulse of plants and connected it to a plant. The plant, with its roots, was carefully picked up and dipped up to its stem in a vessel containing bromide, a poison. The plant's pulse beat, which the instrument recorded as a steady to-and-fro movement like the pendulum of a clock, began to grow unsteady. Soon, the spot vibrated violently and then came to a sudden stop. The plant had died because of poison.



Although Jagdish Chandra Bose did invaluable work in Science, his work was recognized in the country only when the Western world recognized its importance. He founded the Bose Institute at Calcutta, devoted mainly to the study of plants. Today, the Institute carries research on other fields too.



Jagdish Chandra Bose died on November 23, 1937.

Vikram Sarabhai Biography

Vikram Sarabhai Biography

Born: August 12, 1919

Died: December 31,1971

Achievements: Considered the Father of the Indian space program; instrumental in establishing the Physical Research Laboratory (PRL) in Ahmedabad in November 1947; was Chairman of the Atomic Energy Commission. He along with other Ahmedabad-based industrialists played a major role in the creation of the Indian Institute of Management, Ahmedabad.



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.



After his matriculation, Vikram Sarabhai proceeded to Cambridge for his college education and took the tripods degree from St. John's college in 1940. When World War II began, he returned home and joined as a research scholar under Sir C. V. Raman at the Indian Institute of Science, Bangalore His interest in solar physics and cosmic ray led him to set up many observation stations around the country. He built the necessary equipment with which he took measurements at Bangalore, Poona and the Himalayas. He returned to Cambridge in 1945 and completed his Ph.D in 1947.



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.



With active support from Homi Bhabha, Vikram Sarabhai, set up the first Rocket Launching station (TERLS) in the country at Thumba near Thiruvananthapuram on the Arabian Coast, as Thumba is very close to the Equator. The first rocket with sodium vapour payload was launched on November 21, 1963. In 1965, the UN General Assembly gave recognition to TERLS as an international facility.



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.

Dadabhai Naoroji Biography

Dadabhai Naoroji Biography

Born: September 4, 1825

Died: June 30, 1917

Achievements: First Indian to become a professor of the college; instrumental in the establishment of the Indian National Congress; was President of the Indian National Congress thrice; the Congress' demand for swaraj (self-rule) was first expressed publicly by him in his presidential address in 1906



Dadabhai Naoroji is fondly called as the "Grand Old Man of India". He is viewed as the architect who laid the foundation of the Indian freedom struggle.



Dadabhai Naoroji was born in a poor Parsi family in Bombay on September 4, 1825. His father, Naoroji Palanji Dordi, died when Dadabhai Naoroji was only four years old. He was raised by her mother Maneckbai who despite being illiterate herself ensured that Dadabhai Naoroji got best English education possible. As a student Dada Bhai Naoroji was very good in Mathematics and English. He studied at Elphinstone Institution, Bombay and on completion of his education he was appointed the Head Native Assistant Master at the Elphinstone Institution. Dadabhai Naoroji became a professor of Mathematics and Natural Philosophy at Elphinstone Institution at the age of 27. He was the first Indian to become a professor of the college.



Dadabhai Nauroji entered the political fray in 1852. He strongly opposed the renewal of lease to the East India Company in 1853. He sent petitions to the English government in this regard. But the British government ignored his pleas and renewed the lease. Dadabhai Naoroji felt that the British misrule of India was because of ignorance of the Indian people. He set up the Gyan Prasarak Mandali (Society for Promotion of Knowledge) for the education of adult menfolk. He wrote several petitions to Governors and Viceroys regarding India's problems. Ultimately, he felt that the British people and the British Parliament must be made aware of India's plight. In 1855, at the age of 30 he sailed for England.



In England, Dadabhai Naoroji joined several learned societies, delivered many speeches and wrote articles on the plight of India. He founded the East Indian Association on December 1st, 1866.

He got a resolution passed in British Parliament for holding preliminary examinations for the I.C.S. in India and England simultaneously. He also got the Wiley Commission, the royal commission on India expenditure, to acknowledge the need for even distribution of administrative and military expenditure between India and England.



Dadabhai Naoroji was instrumental in the establishment of the Indian National Congress founded by A.O. Hume in 1885. Thrice he was elected to the post of the President of the Indian National Congress, in 1886, 1893 and in 1906. During his third term, he prevented a split between moderates and extremists in the party. The Congress' demand for swaraj (self-rule) was first expressed publicly by him in his presidential address in 1906. Dadabhai Naoroji believed in non-violent and constitutional methods of protest. He died at the age of 92 on June 30, 1917.

Madam Cama

Madam Cama

A prominent personality of the Indian Nationalist Movement, she was born as Bhikaiji Rustom Cama on 24th September, 1861 to a Parsi family in Bombay (now Mumbai). Well, we are talking about none other than Madam Cama, who is a well known freedom fighter. She came from a pretty well off family and her father Sorabji Framji Patel was a powerful member of the Parsi community. In this article, we will present you with the biography of Madame Cama.

Bhikaji took education from Alexandra Native Girl's English Institution. From the very beginning, she was a very sincere child. She always admired the personalities of the Nationalist Movement. On the 3rd of August in the year 1885, she tied her wedding knots with Rustom Cama, an affluent pro-British lawyer. She did not enjoy her married life and spent most of her time performing altruistic activities. Read on to know the complete life history of Madam Bhikaji Rustom Cama.



In the year 1896, the Bombay presidency was hit by a natural calamity, which had adverse effects on the city. Bhikaji was instrumental in the activities undertaken to provide assistance to the afflicted people. While rescuing other people and inoculating them, she herself became a victim of the infection. She became very weak, but somehow managed to survive. In the year 1902, she went to Europe for subsequent medical care and convalescence.



During her stay in London, she got a message that her return to India can take place subject to the promise that she would not participate in the Nationalist Movement. She refused to make such a promise and remained in exile in Europe. She died in the Parsi General hospital in Bombay (now Mumbai) in the year 1936. While Madam Cama was in London, she served as the private secretary to Dadabhai Naoroji, who was the first Asian to be elected to the British House of Commons.



When Bhikaji Cama was in Paris, she happened to come across a number of notable leaders of the Indian Nationalist Movement. In Holland, they secretly published and circulated the revolutionary literature for the Nationalist Movement. During her stay in France, the British Raj authorities requested her extradition, but the French Government did not show their willingness and refused to cooperate. In return, the Britishers confiscated Madame Cama's legacy.


Bhikaji Cama has always been actively involved in fighting for gender equality. On August 22, 1907, she raised the flag for India's Independence at the International Socialist Conference in Stuttgart, Germany. There are many cities in India that have streets and places being named after Bhikaiji Cama. On 26th January 1962, the Indian Posts and Telegraphs Department issued a stamp to acknowledge her work and give her honor. The Indian Coast Guard consists of a ship that has been named after her.

Vinayak Damodar Savarkar

Vinayak Damodar Savarkar was born on May 28, 1883 into a family of jagirdars (landlords) in the village of Bhagpur near Nasik. Vinayak was one of four children others being, Ganesh (Babarao), Mainabai and Narayan, born to Damodarpant Savarkar and Radhabai. Being descendents of a line of Sanskrit scholars, the Savarkars inculcated the love of learning into their children. Vinayak and Babarao were sent to the Shivaji School in Nasik. When Vinayak was nine years old, his mother died of cholera. Damodarpant himself looked after his children thereafter.
Vinayak's father died of plague in 1899. The burden of the family fell on Babarao's shoulders. Vinayak's patriotic spirit found an outlet through an organization called the Mitra Mela that he formed. Vinayak inducted young patriotic men like himself into the Mela. He encouraged the members of the Mela to strive for "absolute political independence for India" by whatever means necessary. In the event of an armed revolt the young crusaders toughened themselves through physical training. The Mitra Mela served the city of Nasik in many ways, especially during the plague when the group carried victims for cremation.

In March 1901, Vinayak was married to Yamunabai, daughter of Ramchandra Triambak Chiplunkar, who agreed to help with Vinayak's university education. After his matriculation examination, Vinayak enrolled in the Fergusson College in Poona in 1902.
Savarkar very soon dominated campus life. He, along with a group of students began dressing alike and using swadeshi goods only. He renamed the "Mitra Mela" as "Abhinav Bharat" and declared that "India must be independent; India must be united; India must be a republic; India must have a common language and common script." In 1905, a huge Dussehra bonfire of foreign goods was lit in Poona by Savarkar and his friends to express resentment toward the partition of Bengal. Vinayak left for London to study law in June 1906 on receiving a scholarship. The "study of law," he said "shows the vital points in the system of government, and accurate base where to strike at advantage." He vowed never to take up service under the British Government and never to accept payment from them.
Savarkar stayed at the India House in London, which was established by Pandit Shyamji, a patriot, scholar and social reformer. Savarkar founded the Free India Society which held weekly meetings and celebrated Indian festivals and anniversaries of important figures and days in the Indian freedom struggle. On May 10, 1907, scuffles broke out between Indians and Britishers at the celebration of the Golden Jubilee of the 1857 martyrs organized by the Free India Society. In 1908, Savarkar completed "the History of the War of Indian Independence." The text was banned by the British even before it was published for being "revolutionary, explosive and seditious." The book was published in France and Germany later and it did much to inspire revolutionaries like Bhagat Singh and Subash Chandra Bose. In 1909, Madanlal Dhingra, follower of Savarkar, shot Sir Wyllie of the India Office after failing in his attempt on the Viceroy, Lord Curzon's life, for the atrocities committed on Indians. Dhingra was imprisoned and a meeting of Indians in London planned to unanimously condemn his action. At the meeting Savarkar angrily shouted, "No, not unanimously!" The meeting became unruly, Savarkar's spectacles broke and blood ran down his face. The meeting was broken up with Surendranath Banerjea leaving in protest of the attack on Savarkar. That night Savarkar wrote to the London Times to clarify the reasons for his action. He stated that the meeting had no right to condemn Dhingra like a law court.
In India, Savarkar's elder brother led an armed movement against the Minto Morley reforms. Babarao was sentenced to transportation for life to the Andamans jail. In protest, a youth called Kanhere shot dead the British Collector of Nasik, Mr. A.M.T. Jackson. Savarkar was implicated in the murder of Mr. Jackson because of his contacts with the India House. Savarkar moved to Madame Cama's residence in Paris. A warrant was issued and Savarkar was arrested on March 13, 1910. In his last letters to a close friend, he conveyed his plan to attempt to escape from custody at Marseilles. His friend was to be waiting there with a car. The escape attempt at Marseilles failed. The car arrived too late.
Savarkar was brought to Bombay on the S.S. Morea and detained at Yeravada jail. Savarkar was tried and found guilty on the counts of "waging war by instigation using printed matter, and providing arms... (and) for abetting the murder of Mr. Jackson (p.118, Berry)." Savarkar was awarded 25 years imprisonment on the former charge and 25 years for the latter. A sum total of 50 years imprisonment which he was to serve at the Andamans prison. "Veer" Savarkar was only 27 years old at the time of his sentencing!
Savarkar arrived at the Andamans prison on July 4, 1911. Life for the prisoners was very harsh. Savarkar's day began at 5 a.m. chopping trees with a heavy wooden mallet and then he would be yoked to the oil mill. If prisoners talked or broke queue at mealtime, their once a year letter writing privilege was revoked. Savarkar withdrew within himself, quietly and mechanically doing the tasks presented to him. He was successful in getting permission to start a jail library. With great effort and patience he taught the illiterate convicts to read and write.
In 1920, Vithalbhai Patel demanded the release of the Savarkar brothers in the Central Legislative Assembly. Tilak and Gandhiji also appealed for Savarkars freedom. On May 2, 1921, the Savarkar brothers were brought back to India on the S.S. Maharaja.
Savarkar remained imprisoned in Ratnagiri Jail and then in Yeravada Jail until January 6, 1924 when he was freed under the condition that he would not leave Ratnagiri district and abstain from political activity for the next five years. While in Ratnagiri Jail, Savarkar wrote "Hindutva" which was smuggled out and published under the pen-name "Maharatta." On his release, Savarkar founded the Ratnagiri Hindu Sabha on January 23, 1924 which aimed to preserve India's ancient culture and work for social welfare.
Through the Sabha, Savarkar worked hard to protect minority rights. During the celebration of Hindu festivals, Savarkar visited Muslim and Christian homes to promote good will. He encouraged intercaste marriage and assisted Dr. Ambedkar in the liberation of the untouchables. He appealed for a wider use of Hindi as the mother tongue and suggested reforms to the Devanagiri script to facilitate printing. While in Ratnagiri he wrote the "Hindu Padpadashashi" and "My Transportation for Life" and a collection of poems, plays and novels.
At the end of his five year confinement in Ratnagiri, Savarkar joined Tilak's Swaraj Party and founded the Hindu Mahasabha as a separate political party. He warned of the Muslim League's designs of partitioning the nation. In 1937, Savarkar was elected President of the Hindu Mahasabha. He toured the nation widely and delivered the simple message that followers of Vedism, Jainism, Buddhism and Sikhism were all Hindus.
At declaration of war by Britain on Germany and the arbitrary inclusion of India in the war, Savarkar said that Britain's claim of safeguarding human freedom was simply meaningless.
Savarkar agreed to join hands with the Congress in support of Gandhiji's Quit India movement as long as the Congress did not compromise the unity of the nation to the Muslim League. "The Quit India Movement must not end in a Split India Movement!" he thundered on a BBC broadcast of his speech.
On August 15, 1947, Savarkar proudly unfurled the national flag along with the saffron flag of the Mahasabha. Pakistan invaded Kashmir in October 1947 and Gandhiji began a fast for peace and Muslim rights on January 13, 1948. The Mahatma was assassinated 17 days later.
Gandhi's assassin, Nathuram Godse, was once a worker of the R.S.S. (Rashtriya Sveyamsevak Sangh), the miliant wing of the Mahasabha. Mass arrests of the Hindu Mahasabha and RSS workers ensued. Savarkar was arrested on the charge of conspiring to the murder on February 4, 1948. Godse and Apte, another accused, denied Savarkar's involvement in the crime. Savarkar condemned "the gruesome assassination of Mahatma Gandhi" and denied involvement in the crime. Savarkar was acquitted on February 10, 1949.
As Savarkar aged, he saw his grim prophecies coming true. China invaded India in 1962 and Pakistan attacked India in 1965. When the Indian Army entered Lahore, Savarkar rejoiced saying that the "best way to win a war was to carry it into the enemy's land (p. 136, Berry)."
"Veer" Savarkar died on February 27, 1966.
