Jagdish Chandra Bose: Biography Of A Scientist

Jagdish Chandra Bose biography. The World-Famous Scientist Of India was born on 30 November 1858. He was born in a small town called Maimansingh in East Bengal. His father, Shri Bhagwan Chandra Bose, was the Deputy Magistrate. Jagdish was the only son of his parents and the only brother of five sisters. Jagdish was a nature lover since childhood. He used to pay attention to everything and tried to get to the bottom of it. Various types of questions and answers come into his mind, and he keeps trying to find answers to those questions. Sometimes he used to ask his father the answer to the questions arising in his mind. The father used to answer his son’s questions properly and also used to encourage him.

Sending children to an English school at that time was considered a matter of prestige for the aristocracy. But Bhagwanchandra Ji admitted his son to the Bengali school of Faridpur for elementary education. Jagdish continued to study in this school for 5 years. All the teachers and students were very much impressed by his talent. Since childhood, Jagdish Chandra was curious to know the secret of nature. Near the house, he dug a big pit and filled it with water. In it, he used to bring frogs, fishes, and snakes and put them in water. Jagdish had built a small hut near the house, in which he started raising rats, squirrels, and rabbits. He studied the activities of these organisms very closely. In 1869, Magistrate Bhagwan Chandra was made an assistant commissioner, and he was transferred to Vardhaman.

Jagdish Chandra Bose Biography


Jagdish was 10 years old at that time. Bhagwanchandra Ji got Jagdish admitted to St. Xavier’s School, where Jagdish started living in the hostel. Most of Jagdish’s classmates at St. Xavier’s School are Europeans. Jagdish had studied through the Bengali language until now, but in Xavier, he had to study English. Because of this, he would find it difficult to communicate with his classmates and teachers. Jagdish had left everyone behind in the examination with hard work and self-confidence. After that, the behavior of his classmates towards him changed. They now started respecting Jagdish. Jagdish had planted a separate garden of his own in the corner of the hostel. In which he also planted different types of plants. While there, he had prepared a small river naturally; he had also made a pool on the river and also raised rabbits and pigeons.

In 1875, Jagdish passed the entrance examination. After that, he joined St. Xavier’s College, Kolkata. Jagdish’s interest in physics and eccentricity. In 1879, Jagdish graduated from St. Xavier’s College. Jagdish wanted to go to England for further studies, but his father’s income had stopped by then. But his mother arranged for him to go to England by selling some jewelry.

In 1880, Jagdish left for England, but on the way, he fell ill with Kala-azar fever. In some way, after reaching London, he took admission to the university. Enrolled in the preparatory class of medicine, he began to study biology and botany. Jagdish once again suffered from Kala-azar while studying anatomy. His headmaster and well-known physician, Dr. Ringer, advised him to quit his studies as the old and damaged body odor could worsen his illness. Jagdish decided to leave his medical studies, and he joined the University of Cambridge from the University of London.


In 1881 Jagdish was elected a scholar in Christ College. He chose natural science to study at Christ College. His fever was still not completely cured. In 1884, Jagdish passed the B.Sc examination at Cambridge University. Then he was 25 years old. Now he started preparing to return to India. Jagdish returned to India through his brother-in-law, Mr. Anand Mohan Bose, living in England, with a letter of recommendation from the then Minister of India, Mr. Kimberley. He was met at Shimla by the then Viceroy Lord Ripon. Lord Ripon first interviewed him and then ordered the Director of Education of Bangla that Jagdish should be placed in a higher post in the Education Department. But the education director asked him to take up some small posts. Jagdish did not accept this.

He again met the Viceroy. He was eventually appointed to Provisional Professor of Physics at the Presidency College, Kolkata, in 1885. Jagdish Chandra Bose worked with full dedication and hard work. In 1987, Jagdish Chandra was married to a young woman named Abla Devi. At the time of marriage, Abla Devi was a third-year student at the Medical College, Madras. Being a medical student, she had good knowledge of science. Shortly after Jagdishchandra’s marriage, his father Bhagwanchandra died, and two years after his death, Jagdish’s mother also died.


Jagdish Chandra used to teach college students with full dedication and hard work. The students also respected him a lot. Jagdish Chandra used to go to the laboratory after teaching the students and do various experiments there. Although he used to do all the experiments at his own expense, the college authorities did not like it. Fighting tough with the circumstances, Jagdish Chandra collected laboratory equipment from his earnings. Jagdish had a special interest in physics. First, he started his work on the microwave. Starting his research in Hertz waves, he realized that he must find natural substances that polarize the transmitted electric beam. During the experiment, he realized that if a material polarizing light is also found to polarize an electric beam, then the similarity between electric radiation and light can be proved more fully.

Jagdish Chandra Bose did some tests with millimeter microwaves. From these tests, he found that some medium-sized crystals polarize normal rays and polarize electric rays in the same way. It was an important discovery of Jagdish Chandra. His discovery was first demonstrated in the college. It was then publicly demonstrated in the presence of the Governor at the Kolkata Town Hall in 1895. The waves reached the receiver, passing through three walls 75 feet from the radiator, from which the pistol was fired, and the bell rang. No one had ever made such a discovery before. The Governor honored Jagdish Chandra Bose for this important discovery and encouraged further research work.


The Western scholars also never imagined that an Indian would amaze the world with his talent in modern science. But Jagdish Chandra Bose proved that even the scientists here are capable of making achievements. By the end of 1895, Jagdish Chandra Bose came under the category of peak physics. His wish was to show him by sending a wireless message to his residence, located about 1 mile from the Presidency College, but his wish could not be fulfilled.
In 1896 he had to go to England. Impressed by the talent of Jagdish Chandra Bose, the Royal Society of Britain decided to financially support him in his research work and publish his author. But instead of cooperating with the college authorities and the education department, obstacles were created.

On 29 January 1897, Jagdish Chandra was invited to speak at the Royal Society of Britain. In this speech series, he gave his speech as well as demonstrated his instrument. In his speech, he mentioned microwave radiators, springy circular grows, and all other supporting experimental instruments needed to demonstrate how electrical radiation is reflected, permeated, and polarized with a view? Marconi invented wireless telegraphy based on Jagdish Chandra Bose’s discovery of electromagnetic waves. Jagdish Chandra Bose returned to India on 23 April 1897. About a month later, a representative of ‘The English Man’ magazine met Jagdish Chandra Bose and published a report. Jagdish Chandra Bose, with his intelligence, created many such papers that could record radiation much shorter than the long radio waves of Hertz.

Work of Jagdish Chandra Bose

Working as a receiver for electrical waves, he found that the sensitivity of the metallic detector was lost due to continuous microwave radiation. But after resting for a sufficient period, the detector regains its sensitivity again above normal. He realized that the metal detectors acted like detectors that detect muscle fatigue in animals. Just as the animal’s muscles return to action after sufficient rest, the non-living receiver should also be active again after rest. Jagdish Chandra Bose left the receiver aside for several days to set up his experience. Later, when he saw the receiver, he was very surprised. The receiver had completely stopped working.

Thus Jagdish Chandra Bose (biography) explained that the basic molecular change that occurs due to stimulation in a secretory cell is the same as the non-living substance, which is not used continuously. Jagdish Chandra Bose started researching plants from the year 1902. He determined that trees perform activities like Plants And Animals from his experiment, so it is not appropriate to believe that trees are non-living. In 1930, the Government of India honored Jagdish Chandra Bose (biography) with the title of CI. After that, he was again sent to England, America, and Japan. In 1915, he retired from the post of headmaster of the college, but the government continued to pay him full salary for the rest of his life. This great scientist of India left this world forever on 23 November 1947.
