Jagadish Chandra Bose, Bangladeshi-Indian physicist, biologist, botanist, and archaeologist (b. 1858)

Sir Jagadish Chandra Bose

(;, IPA: [dʒɔɡodiʃ tʃɔndro boʃu]; 30 November 1858 – 23 November 1937) was a biologist, physicist, botanist and an early writer of science fiction. He pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and was a major force behind the expansion of experimental science on the Indian subcontinent. IEEE named him one of the fathers of radio science. Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. A crater on the moon has been named in his honour. He founded Bose Institute, a premier research institute of India and also one of its oldest. Established in 1917, the institute was the first interdisciplinary research centre in Asia. He served as the Director of Bose Institute from its inception until his death.

Born in Munshiganj, Bengal Presidency, during British governance of India (now in Bangladesh), Bose graduated from St. Xavier's College, Calcutta (now Kolkata, West Bengal, India). He went to the University of London, England to study medicine, but could not pursue studies in medicine because of health problems. Instead, he conducted his research with the Nobel Laureate Lord Rayleigh at Cambridge and returned to India. He joined the Presidency College of the University of Calcutta as a professor of physics. There, despite racial discrimination and a lack of funding and equipment, Bose carried on his scientific research. He made progress in his research into radio waves in the microwave spectrum and was the first to use semiconductor junctions to detect radio waves.

Bose subsequently made a number of pioneering discoveries in plant physiology. He used his own invention, the Crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for a patent for one of his inventions because of peer pressure, his objection to any form of patenting was well known. To facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as quivering of injured plants, which Bose interpreted as a power of feeling in plants. His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926). In a 2004 BBC poll, Bose was voted seventh Greatest Bengali of all time. He spent the last years of his life in Giridih. Here he lived in the house located near Jhanda Maidan. This building was named Jagdish Chandra Bose Smriti Vigyan Bhavan. It was inaugurated on 28 February 1997 by the then Governor of Bihar AR Kidwai.
