Guglielmo Marconi’s first transatlantic radio signal

Originally shared by Ed Pearce

Guglielmo Marconi received the first transatlantic radio signal on December 12, 1901 in St John’s, Newfoundland.

At the turn of the 20th century, Marconi began investigating the means to signal completely across the Atlantic, in order to compete with the transatlantic telegraph cables and prove that wireless waves were not affected by the curvature of the Earth. He established a connection on December 12, 1901 between a 164 foot antenna in Poldhu, Cornwall and a receiver in St John’s, Newfoundland using the 3 morse dots of „s”.

Marconi shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun „in recognition of their contributions to the development of wireless telegraphy.”
