     Many people know the names Alexander Graham Bell and Thomas Edison. However, most people don't

know the name of the man who invented the television, Philo Farnsworth.

      Philo Farnsworth was born in 1906 and grew up on a potato farm. As a boy, he loved to learn about

science, and he read a lot of science books. When he was only thirteen years old, he drew a picture of a

machine that could send pictures as radio sends sounds. He got the idea from the way the potatoes were

planted in the field. The potatoes grew in long lines, side by side. This made a shape in Philo's mind. This

shape helped Philo think of a way to send the TV picture onto a piece of glass. But he was poor, so Philo

could not try to make his idea into a machine at that time.

      Later, Philo worked at many different jobs. He worked with trees. He worked on broken radios. He

worked on trains. He also worked as a street cleaner. At last, two rich men heard about his idea for television,

and they gave him the money to make it. On September 7th, 1927, they watched Philo test the machine he

built. When Philo turned on the machine, a small line could be seen on the glass. Philo said,"There you have it,

electric television."

     Later, a big company, RCA, said they had made the first television. Philo had to spend a lot of money on

lawyers to fight them. Finally, he won. Then, World War Two started in 1939. During the war, Philo spent a

lot of money helping the US army instead of building up his television company. After the war, other bigger,

richer companies started making televisions. In the end, Philo had to sell his company.
