Who invented the telephone?

It is generally said that the inventor of the telephone was alexander bell, an English-American, who obtained a patent for the invention of the telephone in 1876. However, there are other claims that Bell was not the first person to invent the telephone. Some people think that, according to the experiment of British Standard Telephone and Telegraph Company in 1947, the device invented by German Philip Reiss as early as 1863 already has the function of telephone. In the United States, where Bell obtained the patent for invention, the House of Representatives decided to deprive Bell of the qualification of telephone inventor, but thought that the Italian Meiwuqicai was the inventor of telephone. meucci invented the telephone device in order to contact his sick wife, and it was publicly displayed in 186. Because he couldn't afford the permanent patent fee, Bell in the same laboratory applied for the patent first. No matter who the inventor of the telephone was, we can know that this small device fundamentally changed the way of human contact.
