Answer 2

The invention of radio came in two parts. Wireless telegraphy is generally attributed to Guglielmo Marconi but Alexander Stepanovich Popov and Nikola Tesla also played roles in the development.

Reginald Fessenden, Lee De Forest, and Edwin H. Armstrong played important roles in the development of wireless telephony, but Armstrong was probably the greatest contributor to this technology.

Armstrong also played a part in the development of television, but he was one of a number of inventors, engineers and scientists who contributed to its development.
