Bell was a poor student in school but had a remarkable talent for solving problems.

While he did not receive a university degree, his active mind allowed him to pursue his dream of inventing a machine that could mimic human speech.

At the age of twenty-five, Alexander Graham Bell founded a school in Boston, Massachusetts, and taught deaf children to speak.

He later became a professor at the Boston University School of Oratory.

He was a gifted inventor who built a machine to separate husks from grain.

Bell was fascinated by the idea of sound recording and playback and began experimenting with the technology.

Alexander Graham Bell's most famous invention is the telephone.

This invention has changed the way humans communicate with one another.

People can now send and receive phone calls from across the world.

The telephone also changed the way the deaf and mute can educate themselves.
