In 1906, Lee De Forest invented the first amplifier. Until amplifiers were discovered, performers relied on the acoustics of a given space to amplify their voices. Opera artists were expert proponents of this performance genre.
One of the more powerful uses of amplifiers was a political rally. Suddenly, a powerful speaker could command the attention of thousands of people, live. Every great technology has seen uses that are good and evil – the amplifier was no different.
On the one hand, amplifiers were a critical aide in Adolf Hitler’s rise to power.
And, on the other hand, they also helped Martin Luther King Jr. create change that enabled better lives for millions of African American in following generations.
Similarly, all the technology around us can be used to make things better… or worse.
As always, it is our choice.
