Some observers begrudge Marconi his reputation as the 'father of wireless' arguing he deserves credit for wireless telegraphy alone. They argue that sending messages in Morse code hardly compare with the subsequent developments that enabled the broadcasting of speech and music.
This is a poor line of reasoning. Without the invention of wireless telegraphy, the transmission of sound might never have progressed beyond cable and telephone means to the airwaves. And without wireless telephony, which Marconi also helped develop, broadcasting as we know it would have been impossible.
Because the craze for 'listening in' (as radio listening was first called) first swept the US, where regulations were few or difficult to enforce, it has even been suggested that the credit for developing broadcast technology should belong to Americans alone, and three in particular: Dr. Lee de Forest, Edwin Armstrong and David Sarnoff.
In fact, to a greater or lesser degree, they all owed their achievements to Marconi or his colleagues. Dr. Lee De Forest claimed to be the 'father of radio', yet he built his career on adapting a prior invention, the thermionic valve, invented by Ambrose Fleming, Scientific Advisor to the Marconi Company. Armstrong's work on detecting signals of high frequency was in turn inspired by an employee of Marconi's, H.J. Round. Starting as Round's junior and Marconi's protégé in New York, Sarnoff was employed by Marconi's US subsidiary that by merger became the Radio Corporation of America (RCA), which became the largest broadcast manufacturing enterprise in the world.
The Marconi Company can lay claim to achievements equally important on a world scale. Not only did it transmit the world's first live professional music recital, but it also took the lead in founding the consortium of manufacturing interests that developed into the publicly-funded BBC, setting world standards in public service broadcasting to this day.
