Jagadish Chandra Bose

        Jagadish Chandra Bose

Jagadish Chandra Bose was born on 30 November 1858 in Mymensingh (now in Bangladesh). His father Bhagaban Chandra Bose was a deputy magistrate. Bose received early education in a vernacular village school. He was sent to Kolkata at the age of 11 to learn English and was educated at St. Xavier's School and College. He was a brilliant student. He passed his Bachelors in physics in 1879.

 In 1880, Bose went to England. He studied medicine at London University for a year but gave it up because of his 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 BSc degree and Natural Science Tripos (a special course of study at Cambridge).

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 there. 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.

 Jagadish Chandra Bose later switched from physics to the study of metals and then plants. He was the first to prove that plants too have feelings. He invented an instrument to record the pulse of plants. 


Although Jagadish 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 out research in other fields too. Jagadish Chandra Bose died on 23 November 1937.
Location: Mymensingh, Bangladesh
