Which Scottish-born inventor patented the telephone in 1876?

The Scottish-born inventor who patented the telephone in 1876 was Alexander Graham Bell. The United States Patent Office issued Bell’s patent, number 174,465, on 7 March 1876, covering an apparatus and method for transmitting vocal sounds electrically.

Bell was born in Edinburgh in 1847 and later worked in Britain, Canada, and the United States. His interest in speech and hearing was influenced by his family: his father developed systems for teaching speech, and both his mother and his wife were deaf. Bell’s experiments with telegraphy and sound transmission eventually led to the telephone.

The patent milestone was part of a fiercely contested race. Elisha Gray filed a telephone-related caveat on the same day Bell’s application was submitted, and other inventors, including Antonio Meucci, had developed earlier voice-transmission experiments. Nevertheless, Bell is the standard answer because he secured the landmark patent credited with the first practical telephone. Bell and Thomas Watson demonstrated intelligible speech over the device in Boston on 10 March 1876.
