Jagadish Chandra Bose
Bikrampur (Munshiganj), Bengal Presidency
Archival Overview
Indian polymath who pioneered millimeter-wave radio transmission, invented the semiconductor crystal radio detector, and invented the crescograph to prove that plants respond physiologically to electrical, chemical, and emotional stimuli.
Biographical Record
Sir Jagadish Chandra Bose (1858–1937) was educated at Christ's College, Cambridge, returning to Presidency College in Kolkata as professor of physics. In November 1895, Bose gave the world's first public demonstration of wireless millimeter microwave transmission (60 GHz), ringing a bell and igniting gunpowder through walls ahead of Marconi.
Bose refused to patent his semiconductor iron-mercury coherer, advocating open-source scientific knowledge for humanity. Turning to biophysics, he invented the crescograph (capable of magnifying plant movement 10,000 times), proving that plant tissues possess cellular electrical impulses and nervous systems analogous to animals.
