Alexander Graham Bell

"Mr. Watson—Come here—I want to see you."

When Alexander Graham Bell spoke those words, he changed the world. It was 1875, and he had just sent the first message over the telephone. Thanks to his invention, you can dial up a pizza, surf the Internet, e-mail a friend or talk to someone on the other side of the world.

But did you know that the telephone was just one of Bell's many inventions and interests?

• He designed airplanes that set flight records.
• He created a probe to find where a bullet was lodged in a body so that it could be removed.
• He invented devices to locate icebergs and remove salt from sea water.
• He made friends with Helen Keller and helped her and other deaf people learn to communicate better.
