Who invented the telephone?

The telephone was invented by Alexander Graham Bell, who was awarded the first US patent for the invention in 1876. Bell's work in the field of communication technology was pioneering, and he successfully demonstrated the ability to transmit vocal sounds electrically, which fundamentally changed how people communicated over long distances. His experiments with sound and his understanding of the human voice allowed him to create a device that could convert sound waves into electrical signals and then back into sound waves.

While other inventors contributed to the development of communication technology and other inventions in the field of electricity and signal transmission, it was Bell who specifically focused on the idea of transmitting voice over wires, making him the key figure in the invention of the telephone.
