When Was the Phone Invented?

Although there is a dispute over the exact date the telephone was invented, most believe that the first transmission of sound through an electrical device occurred on March 10, 1875, transmitted by Alexander Graham Bell. The first patent for the telephone was issued to Bell in 1876.

Alexander Graham Bell was born on March 3, 1847 in Edinburgh, Scotland. After obtaining a background in music, he was appointed as a professor of Vocal Physiology and Elocution at Boston University. Bell became interested in improving the telegraph as a means of communication and experimented with the ability to convert sound waves into electrical signals which could be sent across wires. He patented this process and later improved upon it, ultimately making the first transcontinental telephone call in January of 1915.
