Guglielmo Marconi

Guglielmo Marconi was an Italian inventor and entrepreneur whose experiments helped establish practical long-distance radio communication. He developed wireless telegraph systems that transmitted signals across the English Channel and later the Atlantic.

Marconi shared the 1909 Nobel Prize in Physics and built a major communications company. Wireless equipment associated with his system became especially important for ships, news transmission and emergency signalling at sea.

Erik Larson’s Thunderstruck uses Guglielmo Marconi’s development of long-distance wireless communication as one half of a paired historical narrative. Marconi’s experiments, commercial battles and transatlantic stations eventually intersect with the Crippen murder case when wireless messages from the Montrose alert police that the fugitive doctor is aboard. The episode turns Marconi’s invention from an abstract technical achievement into a practical tool of modern policing and shows how rapidly wireless was changing the relationship between ships, shore and information.
