Marconi Filed the First Wireless Telegraphy Patent

On June 2, 1896, the young Italian inventor Guglielmo Marconi filed a provisional application at the British Patent Office for a system of signalling through space without wires. It became British Patent No. 12039, the world’s first patent for a practical wireless communication system based on radio waves.

Marconi was only 22 years old. His apparatus paired a Hertzian-wave transmitter with a sensitive receiver known as a coherer, both connected to an elevated aerial and an earth connection. This arrangement let faint electrical signals carry telegraph-style pulses across open distances, with no cable in between.

Within a few years those laboratory sparks would leap the Atlantic.

The provisional filing was followed by a full specification, and the patent was published on March 2, 1897. The breakthrough launched the era of radio, eventually earning Marconi a share of the 1909 Nobel Prize in Physics and reshaping news, shipping, and warfare for the century that followed.
