One night,Philo read a magazine story about the idea of sending pictures and sound through the air.Anyone with a device that could receive this electronic information could watch the pictures and hear the sound.The magazine story said some of the world’s best scientists were using special machines to try to make a kind of device to send pictures.
14yearold Philo decided these famous scientists were wrong and that mechanical devices would never work.He decided that such a device would have to be electronic.Philo knew electrons(电子) could be made to move extremely fast.All he would have to do was find a way to make electrons do the work.
Very quickly Philo had an idea for such a receiver.It would trap light in a container and send the light on a line of electrons.Philo called it “light in a bottle”.
Several days later,Philo told his teacher about a device that could capture(捕捉) pictures.He drew a plan for it,which he gave his teacher.Philo’s drawing seemed very simple,but it clearly showed the information needed to build a television.In fact,all television equipment today still uses Philo’s early idea.
Philo Farnsworth was only 14 years old then.He knew no one would listen to a child.In fact,experts say that probably only ten scientists in the world at that time could have understood his idea.
On September 7th,1927,Philo turned on a device that was the first working television receiver.The image produced on the receiver was not very clear,but the device worked.In 1930,the United States government gave Philo patent documents.These would protect his invention from being copied by others.
