जगदीश चन्द्र बसु Jagadish Chandra Bose

Jagadish Chandra Bose was born in Mymensingh in 1858. He studied at Calcutta, London and Cambridge and taught physics at Presidency College from 1885. His work on millimetre waves in the 1890s is now an IEEE Milestone. He then spent three decades on the electrical responses of plants. He founded the Bose Institute in 1917 and directed it until his death in 1937.

Curated by Nikhil Sharma: a Calcutta professor who refused his salary for three years rather than accept less than a European. In 1895 he sent millimetre waves through walls to ring a bell. He took no profit from his detector. Then he turned his instruments on plants and built a research institute he called a temple.
