Who invented the wireless telegraph in 1896?
Marconi
On 27 July 1896, Marconi successfully demonstrated his wireless telegraphy system by sending a signal between two Post Office buildings.
Who made the first radio broadcast?
In the mid 1890s, building on techniques physicists were using to study electromagnetic waves, Guglielmo Marconi developed the first apparatus for long distance radio communication.
Where was the first wireless telegraph invented?
England
In England, Guglielmo Marconi began his wireless experiments in 1895, and on 2 June 1896 filed his provisional specification of a patent for wireless telegraphy. He demonstrated the system to the British Post Office in July. The British patent was accepted on 2 July 1897, and the US equivalent on 13 July 1897.

Who is known as the pioneer of wireless communication?
The following year, on June 2, 1896, Marconi took out a patent on his invention of the “wireless telegraph by means of electric impulses” in England; a year later he was able to establish a wireless telegraphic connection with a range of 15 kilometers across the Bristol Channel.
What did the wireless telegraph do?
Wireless telegraphy or radiotelegraphy is transmission of telegraph signals by radio waves. Radiotelegraphy was used for long-distance person-to-person commercial, diplomatic, and military text communication throughout the first half of the 20th century.
How did the first wireless telegraph work?
To send a message, an operator at one office would tap on a switch called a telegraph key, creating pulses of electric current which spelled out a message in Morse code. When the key was pressed, it would connect a battery to the telegraph line, sending current down the wire.
