Guglielmo Giovanni Maria Marconi, 1st Marquis of Marconi FRSA: Inventor Of Long-Distance Radio
By | April 22, 2021
Guglielmo Giovanni Maria Marconi was born in Bologna, Italy on April 25, 1874 to Italian nobility. He was the great-grandson of Irish distiller John Jameson (yeah, like Jameson Whiskey), and his illustrious upbringing naturally afforded him the best of education, but Marconi was disinterested in school. Instead, he worked solely with private tutors who nurtured his natural curiosity in science. He was primarily fascinated with the nature of electricity and the possibilities it offered. Even with this lenient approach to education, however, he received poor grades and skipped out on college entirely.
When Marconi was in his early twenties, he read the works of Heinrich Hertz (the guy who proved the existence of electromagnetic waves, which is why we measure them in hertz) and became obsessed with the idea of using these waves to send messages across great distances. Sending voices through the air from miles away may have sounded like witchcraft back then, but now we just call it the radio.
Blinding Her With Science
In the beginning, however, sending any kind of message proved very difficult. He used his connections to work with a professor at the University of Bolonga, Augusto Righi, to develop a "wireless telegraphy" machine using an assortment of established apparatus like the coherer transmitter and antenna. He tinkered with the contraption for two years as he lived with his parents, and while his father expressed worry and doubt about his son's seemingly stunted and obsessive behavior, his mother was steadfast in her support, going so far as to bring his dinner to his room so he could eat on his own schedule. Her faith proved justified when, in the dead of night in December 1894, a young Marconi ushered her up to the attic laboratory, where he showed her a button that rang a bell all the way across the room when pressed. No wires, no magic. Just science.
By building taller antennae and grounding them, he quickly proved he could transmit signals from two miles using radio waves (electromagnetic waves between 30-300 gigahertz). In 1896, after getting a shrug from the Italian government that failed to see his work's usefulness, Marconi went to the British government to show proof of concept, successfully transmitting Morse code over a wireless telegraph from over six miles away. With a bit of showmanship, Marconi sent the first overseas telegraph through the Bristol Channel. The received message read, "Are you ready?"
