It was early September 1913, in the early days of radio communication. Operators at telegraph stations along the east coast of the United States were astonished to hear music coming through their receivers, but no one could identify its source. Ships (paquebot, yacht…) at sea also reported picking up mysterious melodies over the airwaves.
The mystery was solved when the telegraph station at Sandy Hook, opposite New York, received a message asking operators to listen carefully to the music that was about to follow. Moments later, they heard La Marseillaise and America.
The First “Wireless Piano”
The broadcast originated from L’Hirondelle, the yacht of Prince Albert I of Monaco, which was preparing to enter New York on 9 September 1913 after crossing the Atlantic via the Azores and Nova Scotia while conducting scientific surveys. A passionate biologist and oceanographer, the Prince had equipped his yacht with laboratories, earning him the nickname “the Scientist Prince.”
The musical broadcast itself was a remarkable innovation, although the melodies were necessarily simple. They were performed live on an instrument resembling a small piano with about ten keys. Invented by the German Baron von Lepel, the device had been acquired by the Compagnie Générale de Radiotélégraphie. Known as the Piano Sans Fil (“Wireless Piano”), it was an ingenious experiment, although it would soon be overtaken by more advanced broadcasting technologies.
Albert I of Monaco : A Pioneer of Science and Technology
While the musical transmission from L’Hirondelle has secured its place in the history of telecommunications, it also reflects the remarkable personality of its owner.
Prince Albert I of Monaco (1848 1922) was no ordinary ruler. A scientist, explorer, and patron of research, he devoted much of his reign to promoting scientific discovery and technological innovation. Long before oceanography became an established discipline, he recognised its importance and helped shape its development.
Between 1885 and 1915, Albert led numerous scientific expeditions across the Mediterranean, the Atlantic, and even into polar waters. His successive research vessels, including Hirondelle, Princesse Alice, and Princesse Alice II, were floating laboratories equipped with some of the most advanced scientific instruments of their time.
This passion for science explains his presence aboard L’Hirondelle during the 1913 Atlantic crossing. The yacht was far more than a princely vessel; it was a platform for research and experimentation. By allowing equipment capable of transmitting music over radio waves to be installed on board, Albert I once again demonstrated his enthusiasm for technological progress.
The Prince also understood the transformative potential of wireless communication. The sinking of the Titanic just a year earlier had highlighted the vital role of wireless telegraphy in maritime safety. Against this backdrop, the experiment conducted from the princely yacht was more than a novelty or a form of entertainment it offered a glimpse of the new possibilities opened up by radio technology.
The story of the “wireless piano” was part of a much broader vision. Throughout his reign, Albert I championed scientific research and innovation, founding institutions in Monaco dedicated to the study of the oceans and the natural sciences. He firmly believed that scientific progress should benefit society and contribute to humanity’s understanding of the world.
