Who is known for the invention of the telephone?

Alexander Graham Bell is recognized for the invention of the telephone due to his successful patent application in 1876 and his pioneering experiments in the field of sound transmission. Bell's dedication to understanding and improving the transmission of speech led to the development of a device that could convert sound waves into electrical signals and back again, which was fundamental in creating the first practical telephone.

His innovative work in acoustics and speech technology set the groundwork for modern telecommunications. While other inventors, such as Elisha Gray, were also experimenting with similar technologies around the same time, Bell's success in obtaining the patent and effectively demonstrating his invention solidified his place in history as the inventor of the telephone.
