From Cornwall to Cape Cod: The First Transatlantic Radio Greeting

Updated: Jul 21, 2023

#23 Science in History

19 January 1903


On this day in 1903, history was made as King Edward VII of England and President Theodore Roosevelt of the United States exchanged greetings via a radio transmission.

Guglielmo Marconi

The event marked the first time that a reigning monarch and a head of state had communicated with each other through this new form of technology.


The exchange took place between Cape Cod, Massachusetts and Cornwall, England, and was made possible by the work of Guglielmo Marconi, an Italian inventor who had developed the first successful wireless telegraphy system. This system allowed for the transmission of messages through the air without the use of wires, making it a revolutionary form of communication.


The coded radio exchange between the King and the President was a symbol of the growing relationship between the two countries, and the role that technology was playing in bringing them closer together. This was a significant moment in history as it demonstrated that the world was becoming more connected, and that new forms of technology were making it possible for people to communicate and collaborate across great distances.
