Who invented ATT?

Answer 1

The company that became AT&T began in 1875, in an arrangement among inventor Alexander Graham Bell and the two men, Gardiner Hubbard and Thomas Sanders, who agreed to finance his work. Bell was trying to invent a talking telegraph -- a telephone. He succeeded, earning patents in 1876 and 1877. In 1877, the three men formed the Bell Telephone Company to exploit the invention. The first telephone exchange, operating under license from Bell Telephone, opened in New Haven, CT in 1878. Within three years, telephone exchanges existed in most major cities and towns in the United States, operating under licenses from what was now the American Bell Telephone Company. In 1882, American Bell acquired a controlling interest in the Western Electric Company, which became its manufacturing unit. Gradually, American Bell came to own most of its licensees. Collectively the enterprise became known as the Bell System.

Answer 2

Technically it was Alexander Graham Bell because he invented the telephone and then a few short years later went into business with some sharholders on the American telephone and telegraph corp. which was later renamed AT&T.
