- [Narrator] Thomas Edison. It's difficult to imagine life
without his remarkable inventions.
That he developed them
while managing a significant disability
is even more extraordinary.
[upbeat music]
"History Honors 250."
Edison's determination didn't just revolutionize the world.
It also helped him seek out ways to adapt and thrive,
despite losing much of his hearing beginning at age 12.
To experience music,
he employed a technique called bone conduction,
which involved the biting down on a piano or phonograph
to experience the vibrations of sound.
But when it came to his own work,
Edison considered the silence an asset,
claiming that it allowed him
to concentrate on experimentation
and research without distraction.
That focus helped Thomas Edison
forge a legacy of innovation,
including the first city-wide electrical grid,
and even a motorized pen,
later adapted for tattooing,
that continues to impact our lives every day.
