Who invented radio: Bose or Marconi?

Should J.C. Bose, rather than Guglielmo Marconi, be credited with inventing radio?
Independent discoveriesTechnology & engineering
Indian claim
J.C. Bose demonstrated wireless transmission in Calcutta in 1895, before Marconi's first patent (1896), and chose not to patent most of his work.
Evidence for the Indian claim
- Bose's 1895 demonstration in Calcutta and his 1897 London lecture are well documented.
- Some engineers (e.g. P.K. Bondyopadhyay, Proceedings of the IEEE, 1998) argue that the detector Marconi used in 1901 was based on Bose's mercury coherer design.
Commonly credited to
Guglielmo Marconi built the first practical radio-telegraphy system, applied for a British patent in 1896, and sent a signal across the Atlantic in December 1901.
Evidence for the other claim
- Heinrich Hertz first proved radio waves in 1887–88; Oliver Lodge (1894) and Alexander Popov (1895) also demonstrated wireless detection.
- Marconi's system was the first to send signals over long distances and to be developed into a commercial service.
- Bose's own interest was in physics, not in long-distance telegraphy; he did not build a radio service.
What historians and scientists say
Radio has no single inventor. Hertz, Lodge, Bose, Popov and Marconi all made key early steps at about the same time. Bose's experiments were among the earliest and most original, while Marconi made radio practical over long distances.
