Who invented the telephone and when?

The invention of the telephone is credited to Alexander Graham Bell, who was awarded the first US patent for the invention on March 7, 1876. Bell, a Scottish-born inventor and teacher, worked on improving communication devices for the hearing-impaired and developed a device capable of transmitting speech electrically. On March 10, 1876, Bell made his famous first telephone call to his assistant, saying, “Mr. Watson, come here, I want to see you.” Bell’s invention revolutionized global communication, paving the way for the development of telecommunication networks that became essential for modern society.
