Who is the father of radio

“The world’s first wireless telephone conversation occurred in 1880, when Alexander Graham Bell and Charles Sumner Tainter invented and patented the photophone , a telephone that conducted audio conversations wirelessly over modulated light beams (which are narrow projections of electromagnetic waves).”

Bose was among the pioneers of research in radio technology and demonstrated, for the first time ever, wireless communication using radio waves, almost two years before Italian physicist Guglielmo Marconi , who is credited for developing the first proper system of radio communication in 1897.

Guglielmo Marconi , the father of wireless communication and recipient of the 1909 #NobelPrize in Physics passed away on 20 July 1937, 80 years ago today.
