That's true. Bose is also the source of Marconi's radio component and he developed junction based electronics way before it's time. Bose was quite fiercely anti-patent. Marconi patented the coherer in his name.

It is only recently that Bose's contributions in radio and electronics are being acknowledged (colonialism doing what it does) although these were quite well known in Bengal.
