The fourth telephone was invented by Elisha Gray, an American inventor, who filed a patent for his version of the telephone on February 14, 1876, just hours after Alexander Graham Bell filed his own patent application. While Bell is often credited with the invention of the telephone, Gray's design was also significant and contributed to the development of early telephone technology. Gray's device was capable of transmitting vocal sounds using electrical signals, similar to Bell's invention.
