Who was Guglielmo Marconi?

Guglielmo Marconi was an Italian inventor who is most well known for his pioneering work in wireless telegraphy and radio communication. He is credited with inventing the first practical system of long-distance radio communication. His most significant achievement came in 1901 when he successfully transmitted the first transatlantic radio signal from Cornwall, England to Newfoundland, Canada. This break through laid the foundation for modern radio, broadcasting and wireless communication technologies.

Marconi's was awarded The Nobel Prize in 1909 in recognition of his contributions to the development of wireless technologies.

In the late 1880s, radio waves were discovered. It was discovered that radio waves were similar in nature to light but they had a greater wavelength. Scientists explored whether or not it would be possible to use these waves to transmit signals. 

After a great deal of study and learning, Marconi managed to use radio waves to transmit signals over several kilometres. He continued to work hard and develop his discovery, eventually achieving transmission over greater ranges. This laid the foundation for wireless transmission of signal through telegraphy and radio.
