American Inventors

By Nancy

An inventor is a person who creates something new. The following four American inventors changed the way people live many years ago. 

In 1838, Samuel Morse introduced an electric telegraph with a special code system to help people send messages. He invented morse code. Messages sent by morse code contain dots and dashes to show the alphabet letters, numbers, punctuation marks, and other special characters. 

Years later, in 1876, Alexander Graham Bell invented the first telephone. He discovered a way to transmit or send sound across electrical lines. People could use the telephone to talk to each other from long distances. 

Thomas Edison invented the lightbulb in 1879. Until then, people used fire as a main light source. Edison’s bulb used electricity to create light. It was more powerful and less expensive than candles. This is because one light bulb could illuminate or light up an entire room. Centuries later, the light bulb is still a common household item all over the world. 

Orville and Wilbur Wright invented the first successful airplane in 1903. Early inventions such as gliders and aerial steam engines failed. Thanks to the Wright brothers and their clever design, people can travel the world by air.
