Biography | show moreshow less
Guglielmo Marconi, an eminent figure in the history of telecommunication, was born on April 25, 1874, in Bologna, Italy. Recognized as a pioneer in long-distance radio transmission, Marconi's groundbreaking work in wireless telegraphy laid the foundation for all radio-based technology that followed.

Marconi embarked on his scientific endeavors at a young age, developing an interest in electricity and physics. His fascination with the work of Heinrich Hertz and Sir Oliver Lodge on electromagnetic waves led him to conduct his own experiments. In 1895, he achieved a significant milestone when he managed to send wireless signals over a distance of one and a half miles. In 1896, Marconi took his work to England, patenting his invention and forming the Marconi Telegraph Company. He continued his pioneering work in long-distance radio transmission, culminating in the first transatlantic wireless signal from Cornwall, England, to Newfoundland, Canada, in 1901. This achievement shattered the belief that the curvature of the Earth would limit radio transmission to approximately 200 miles.

Marconi was awarded the Nobel Prize in Physics in 1909, shared with Karl Ferdinand Braun, in recognition of their contributions to the development of wireless telegraphy. Notably, he was also a pioneer in developing shortwave radio systems, which significantly improved long-distance communication. Marconi also was an Italian Senator and served as President of the Royal Italian Academy.
