Famous Inventions and Their Inventors

X-rays were discovered in 1895 by a German professor, Wilhelm Roentgen. People all over the world were amazed by his invention, the X-ray machine. This invention was so important that Roentgen won the first Nobel Prize for Physics in 1901.

The telephone was invented by Alexander Graham Bell, a doctor and speech teacher. The first phone call was made by Bell in 1876. He got acid(酸) on his pants by accident and wanted his partner, Thomas Watson, to help him. The first words spoken on the telephone were “Mr. Watson, come here! I need you!”

Television was invented in 1926 by John Logie Baird, a Scottish inventor. Baird’s television certainly didn't look like a television today! Electronic televisions like the ones we have today were invented by Vladimir Zworykin in the 1920s in the United States.

The first computer was built in 1946 by two American engineers, J. Presper Eckert and John W. Mauchly. It was developed for the army, and it was so large that it took up the whole room!

Today computers are involved in almost everything we do and are found almost everywhere we go.
