money could not patent his invention. Meucci took his invention of the telephone to Western
Union but ignored him and kept the materials, not proven but it is said that these materials
were captured by Alexander Graham Bell, who use them to create your phone.

Congress of the United States. Pat Bell was controversial from the start because it was said
Bell had someone who helped him in the patent office and told him in advance that he was
going to compare the two patents that of Gray and Bell to discard the worst and the most
expensive. Bell could thank his friend comparing patents and patent added to hand him a
note in which he described an alternative design just like the Gray.
