His achievements triggered the invention of the wireless telegraph and radio.
30 November 1858 : Birthday of Jagdish Chandra Bose, a pioneer of wireless broadcasting. Indian physicist, biologist, and early writer of science fiction, he pioneered the investigation of radio and microwave optics and laid the foundations of experimental science in the Indian subcontinent.

The Broadcasts targeted white settlers who monitored news from their home and other parts of the world.
