JAGADISH CHANDRA BOSE

Jagadish Chandra Bose
Date of Birth:Nov 30, 1858
Date of Death:1937
Place of Birth:Bengal

Jagdish Chandra Bose was an Indian physicist who pioneered the investigation of radio and microwave optics. Bose was born in Mymensingh in Bengal (now in Bangladesh) on November 30, 1858. His father, Bhagawan Chandra Bose worked as a tax collector for the British East India Company. His family originally hailed from the village Rarikhal, Bikrampur, in the current day Dhaka District of Bangladesh. Having started his studies in a local school, Bose studied at the St. Xavier's School and College at Kolkata. He passed the Entrance examination (equivalent to school graduation) of Calcutta University in 1875. He received a B.A. in Science from Calcutta University in 1879. Next, Bose went to England to study at Christ's College, Cambridge. He received a B.A. from Cambridge University and a B.Sc. from the London University in 1884. After completing his studies in London, Bose return to Kolkatta and was appointed Professor at Presidency College in Kolkatta. Then he became the director of the institute he founded and remained in the post till his death on 23rd November 1937. Jagadish Chandra Bose was one of the pioneers of modern science in India. His research was on the properties of electro-magnetic waves.His major achievement was to demonstrate the similarity of responses to stimulation among the living and the nonliving as well as the fundamental similarity of responses in plant and animal tissues. The British Government knighted him in 1917. He founded the 'Bose Research Institute' in Kolkatta in 1917. Bose was not only a biologist, but also a physicist. Bose believed that by focusing on the boundaries between different physical and biological sciences, he would be able to demonstrate the underlying unity of all things. Bose's biological researches were founded initially by the discovery that an electric receiver seems to show science of fatigue after continued use. He can rightly be called the inventor of wireless telegraphy. Bose was the first in the world to fabricate and demonstrate in public (1985) the device that generated microwaves-radio waves of very short wave length. But his invention was not patented before Guglielmo Marconi (1896) who became internationally recognised as the inventor.
