WASHINGTON, Aug. 29, 2016 /PRNewswire-USNewswire/ --
Following is the daily "Profile America" feature from the U.S.
Census Bureau:
ON THE AIR
Profile America — Monday, August
29th. Two trailblazers in early electronics, whose
inventions changed pastimes the world over, were born in August.
One was television pioneer Philo
Farnsworth, born 110 years ago. He conceived the idea of
television broadcasting while still in high school and realized it
at the age of 21. The other was Lee de
Forest, born in late August, 1873. The Yale doctor of physics invented the three-element
vacuum tube, a step toward creating radio. Holding hundreds of
patents, he was an innovator in not only radio and television, but
also film, as he synchronized sound to motion pictures. Over
217,000 Americans work in the thousands of radio and TV
broadcasting establishments advanced by Farnsworth and de Forest.
You can find more facts about America from the U.S. Census Bureau
