Acharya Sir Jagadish Chandra Bose, CSI, CIE, FRS was a Bengali polymath, physicist, biologist, botanist, archaeologist, as well as an early writer of science fiction. He then went to the University of London to study medicine, but could not pursue studies in medicine due to health problems. He used his own invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues.
