Who invented the telephone?

Explanation:
The main concept here is identifying who first turned a spoken voice into an electrical signal that could be transmitted over a distance, creating the first practical telephone. Alexander Graham Bell achieved this with the first successful voice transmission over a wire in 1876 and secured the patent for the invention, which solidifies him as the inventor of the telephone. Other famous figures are known for different breakthroughs—Edison for the phonograph and electric light, Tesla for alternating current and wireless work, Marconi for wireless telegraphy—so they don’t fit as the inventor of the telephone. Bell’s demonstrated device and patent establish the historical claim.
